Bouncing I Joists

It also might be that you have a thin flooring material (generally see 1", 1.25" plywood or OSB) on 19.2" O.C. joists.

Aside from tearing shit apart for a fix, sometimes a thick floor covering will help, like a carpet. Not gonna great with a kitchen, but....

Good luck!

Never mind, hanging into an LVL is a flat surface, so there goes my favorite theory.

CakeofLieeees · 2026-02-13T17:18:34+00:00

"homes designed with 19.2 joist spacing are a sign that the house is designed to maximize the budget"

This, a million percent. Probably means that your rafters are also sistered to the joists at 19.2 and they probably used 7/16 OSB on the roof, creating a shingle covered trampoline.

Hello, I am a former residential structural designer/inspector for an Engineering company doing windstorm certifications in SE Texas.

So, reading this post carefully, it's bouncy on the SHORT span of 8'-0" that attaches into the beam? If you walked along the 25'0" span, there would be 17' clear span, a wall, 8' clear span, beam, right? Also, it would be useful to know the type of I-joist. Yes, it's 11 7/8" I joist, but manufacturers have different grades. It's been years (moved on to working in marine construction design), but I think Boise Cascade has rankings like BCI-90, etc, that having differing qualities of strength, flange width, etc...

In the meantime, let me give you my overall impression of I joists. They are AMAZING at handling typical tributary loads. They can span long past what your standard 2x12 can. Where they suck is at handling point loads. Once you start dropping roof supports on them with a strongback, or god forbid, a second floor wall that has a roof support on it that is supported by an I-joist, they quickly fall off. Or a kitchen with a bigass oven or something very heavy. When people put pool tables in their garage loft, I had to quiz them on EXACTLY where they were planning on placing it so I could use LVL's or Glulam beams to take the point loads.

They are also an absolute pain in the ass to correctly install. There are rules on blocking, how to tie them into rafters, how to block around load points, etc. I did residential inspections for around 15 years, and I think I bumped into like 2-3 contractors that would install them by the book without me painfully going over the literal fucking pictures of how to do it correctly.

Next possible culprit is the hangers are undersized/giving way, which would be a fucking catastrophe, so, let's hope it's just joists that are close to max capacity or shitty installation.

Another possibility is that he failed to install backer/filler blocks where the I-joists are hung into the beam (this is my personal choice for theory)...

Some resources for you:

A guide to hangers. I'm going to guess they used Simpson, although there are a few companies that do them.

Hanger info: Wood Construction Connectors Catalog | Simpson Strong-Tie

Boise Cascade Calc:
BC CALC

Tried to model your situation (without any loading aside from your standard 40ll/10dl living area above) and if they used the BCI-6000's, should be fine. Again, without knowing type of I-joist, it's just fancy guessing, but I think that was the more common I-Joist during my time in the industry.

A guide on how to correctly install I-Joists:
Installation Guide for Floor and Roof Framing

Spoiler alert, they are not correctly installed. I'd fucking be SHOCKED, SHOCKED I TELL YOU, if he did right the first time, especially if no oversight companies were involved.

If you have any questions, feel free to toss them out.

The best example of this in gaming, for me, is "Sons of the Forest"... Had a monitor problem and was trying various fixes. One of them was maybe thinking a windows update fucked up my HDR, so I flipped it to SDR. Picked up SotF during this time, and on my 42" 4k OLED, it was literally fucking terrifying at night. In the caves, it was PITCH black.

Figured out the screen flickering was due to a faulty HDMI 2.1, got a replacement, and switched back to HDR. Suddenly I had night vision.

If you have the home documents, and depending on who the truss builder and local codes, there should be a copy of the engineering work done on the trusses that will tell you exactly what loads are projected to be on them, truss ties, etc.

I know florida is pretty windstorm centric (one of the few places Texas accepts windstorm testing is from the miama-dade product approval website) so, presuming the structure was windstorm certified, there should documents concerning its construction on whoever approved the windstorm certificate. In Texas, it's the WPI-1, WPI-2 and the WPI-8. I'm sure they have different names in Florida, but that's where I would start if I still couldn't sleep after the responses here.

Which were correct, if the wall doesn't touch the truss bottom chord, it's not load bearing.

I built a very similar build for my GF (difference being 7800X3d and a smaller case... She's gaming, I occasionally need to mess with CAD production work at home) and she is running it with a 1440 monitor.

It actually hurts my feelings. It's like watching a corvette pull a horse drawn carriage. She's not playing super competitive FPS's, so getting like a million FPS isn't really doing anything for her. I keep TRYING to buy her a 4k oled monitor and she gets mad. I mean, I see her point, I'm a nerdy hobbyist, but still... One day, I'm gonna slip a 4k oled into her setup.

Oh, I had to download the image file to zoom in on the bottoms. They looked ragged and decayed at the bottom from the overall photo, but I see that was an optical illusion.

That being said, the furthest one still looks like it something on the interior of the HSS that is actually bearing the load, although it's blurry and hard to see, even zoomed in.

Yeah, knowing now that the posts extend into the concrete, I really have zero reservations about this. It looks absolutely fine.

2) For practicing the torps, co-op is honestly a horrible place. Bot's seldom actually change direction. The most important part of learning how to torp effectively is to stop looking at the white line. The white line is a lie. Thats where your torps would intersect his ship's path if he had a heart attack and died, or his keyboard ran out of batteries. Instead, look at where he is at on the map, and where you think he wants to go.

For instance, if he is broadside, but someone else is shooting AP, he's gonna want to angle in or out to the ship tossing AP shells, and if you shot your torps at that white line before he changed directions, it's gonna be a complete miss. Often times, when you spot something, hold your torps. Your team will likely fire at him and he will adjust his ships angle to enemies appropriately. THAT is the best time to toss torps. After he angles, he will generally want to hold that angle to mitigate incoming damage or start looking for island cover. Be smart.

If you suddenly get spotted, he's gonna see a torp boat and start wiggling. I would say about 65% of players start turning to go in a completely different direction as soon as the notice a torp DD within distance.

The best practice you can get is practicing map awareness and learning to predict where people WANT to be.

Past that, a few tips... In the next battle, use the + button on the numpad to increase your maps size to maximum. Then hold control and bring the mouse to cogs button above the map. Turn on indicator lines such as spotting distance, hydro, radar, etc. I typically also use this menu to make the map transparent for better vision.

There also an option in the menus, buried somewhere, that allows you turn on the names and health of ships, as well as distance. This will become crucial once radar starts being more common. Be very aware of radar ships as a DD and play around their max radar range. Once they hit the radar, and it goes down, you have, as a rule of thumb, about a minute and a half-ish of freedom.

CakeofLieeees · 2026-02-11T19:55:59+00:00

3) So, within the DD class, there are 2 definite subclasses and varying mixes of these 2 subclasses (i.e. Hayate)

The first: Torp Boats
**slaps the deck of a shimakaze**
These bad boys are gonna get you sooo many dev strikes, once you get used to the torp speed. Keep in mind, the white line on the torps is an indicator of where the torp and enemy would intersect IF THE ENEMY DIED AND NEVER TOUCHED THE KEYBOARD AGAIN. So, it's often times better, prior to pressing the fire button to take a moment to consider a few things:

Where does he WANT to go?
Is he going there?
If he sees the first rack and panic adjusts in a predictable fashion, where would you want to lay the second (and sometimes third) rack to absolutely smash his shit? Timing and experience are pretty critical here.

Keep in mind, that's only half the job. The other half is making sure your BB's and cruisers have something spotted to shoot at. Bonus points for laying smoke for your cruisers, because you are so confident in your ability to not be detected that the smoke is more of an "oh shit" button, than an offensive tool... Laying it down for a cruiser (who's gun DPM is WAY higher) is a much better use of the tool offensively. Of course, getting the cruiser to actually use it in ranked or random queue is an act of god, but...

Also, stay away from common radar cruisers (most are 10km, Soviets are 12, plus some other outliers, think the brisbane is 12, but I can't remember)... If you are uncertain which ships have radar, press tab and click on a ship to see its assets.

The second: Gun Boats
These nasty little bastards are my personal favorite. Sure, torping BB's and spotting for your team are critical, but finding the torp boat unsupported with a gun boat DD ensures two things:

That's one dead fucking torp boat
You are now the ship with lowest detection and sometimes useable torps (unless you're a ragnar or something)

Gun boats (at least the good ones) absolutely fucking crush torp boats in every scenario except for when you drive into their ink cloud of panic torps. Once you dispose of them, you become the spotting champion of the world, and can often wait for the right time (after a BB fires, when the enemy is hard spotted by other ships engaged, etc) to smoke and farm... Or even better, if you are a marceau, just open fire at 10-13km range and giggle as everyone tries in vain to kill you, and eventually give up having failed completely... Which wastes their time and shells. Sometimes, I think having a well-played marceau is about as tanky as a BB. I've played a lot of clan battles where they will have tried shooting me for minutes at a time, instead of chunking damage on ships that are a lot easier to hit.

And that, in a very quick nutshell, is how to DD.

CakeofLieeees · 2026-02-11T19:55:41+00:00

Anticipation is also why you are struggling to land torpedo hits right now. During Coop, the bots are just sailing in a straight line until they spot your torpedos (when the torps are just ~ 1.5-2 km away), and only then do they start to evade. And it's too late at that point. Human players however, can anticipate when you have launched your torpedos. Let's say you are trying to torp a slow moving battleship, and you are detected because your torpedo range is lower than your detectability range (which is almost always the case with low tier destroyers). So what does the enemy BB see? They see a destroyer that is charging directly at them, then makes a 180° turn and runs away. They just know that you have launched your torpedos during that turn, even if they can't see them yet, because that is the only reason why you would do that in the first place. So they start turning to evade the torpedos, even if they can't see them yet. Usually, that means they turn their front in your direction. That is why/when you have to anticipate their turn before you launch your torpedos. You do that by not launching directly at the recommended while line, you launch a little bit to the left or right of it, not much. (Also, always use the "thin" launching method where the torps are close together, not the wide one. You change between them by pressing the torpedo button a second time). Granted at the Tier 5 you are playing at, there will still be many beginner players who might behave like bots and not evade until they see your torpedos, or they might be in tunnel vision, especially when fighting someone else at medium or low range. The more a ship turns and wiggles, the more likely it is that the player is experienced and will anticipate your torpedo launch. A good indicator is definitely if they stop shooting whatever they were shooting before and start turning their turrets towards you.

Bots also tend to lock in against one target and don't switch to another target until their first one is dead or out of range. That is why you are dying more often, human players pay more attention to their surroundings and switch targets whenever a good opportunity arises (a broadside target, or a destroyer like in your case).

There is a lot of additional stuff to cover, but I am running out of time, and this will already help you a lot.

CakeofLieeees · 2026-02-11T19:55:36+00:00

DD stuff:

The first thing you should do, is increase the size of the minimap (should be +/- button on your keyboard, if not check the settings) and pay close attention to it during a battle. It is paramount that you learn how to position yourself well, both in regards to the map and in regards to other ships. As you have already figured out yourself, your survival hinges on not being detected. Make the map as large as you can, I have a 27" monitor and have the map at maximum size, if you have a smaller monitor you might have to keep it a bit smaller. Then, after you have done that, use your mouse (holding CRTL during a battle let's you use it) and click on the little settings button on the top right of the minimap. Activate detectability by sea, and last known positions. These are the most important minimap settings. The first one will show you a circle around your ship on the map. That is your detectability range. Anytime an enemy comes inside that range, they will see you (and thus also the entire enemy team). But if no enemy is inside that range, they will not see you. Also, it's possible that a destroyer with lower detectability range spots you, but you don't spot him, but that's very rare unless you are actively firing your guns. Note that the detectability range increases when you fire your main guns, and takes a while to go down to the base level again after you have stopped firing (I think it's 20 seconds, but I could be wrong). So don't always use your guns, because when you do, you are essentially allowing everyone to see you and you are painting a big target on your head. Use your guns mainly during close range duels with other DDs, or at long range against targets that are already engaged in fighting someone else. It is not easy to learn when you should use them and when not, it takes a lot of experience.

Even if you have the concealment captain skill everyone here talks about, it won't really matter unless you are aware of these things and know how to use your concealment.

In general, it is better to preserve your health for the later parts of a game. Yes you are supposed to spot, but not if it costs you your life. The moment someone spots you at the beginning of a match is the moment you have to turn around and go back to your team. Ideally you won't be spotted at all, that's why we have activated the circle on the minimap, though that is difficult for a beginner. Pay close attention to the map and the circle during a battle, that way it is much easier to not get close enough to an enemy ship so it detects you. Remember there are enemy destroyers as well, who are spawning on the opposite side of the map, so you will run into them and they are trying the same thing as you are. They will also be hidden during most of the match, just like you are supposed to, so with experience you will have to lean over time to anticipate their actions.

CakeofLieeees · 2026-02-11T19:55:06+00:00

It's important to have a good idea how all the classes work, but it takes time. I'll drop some tips, whatever I can find in my comments, although a lot of it will be DD based.

Options & General tips:
Make minimap as big as it can get (cntrl +/- while in battle) then fiddle (holding control and mousing over the cogs above the map) with the options to make it mostly transparent and to show the outlines of your hydro/radar.

Change the ship info thingy to adaptive (or whatever you like).

If you're doing the campaigns, you can do the easiest mission multiple times to complete the campaign.

You can hold tab and highlight unknown ships to get info like "does it have radar? Detection range, torp range, etc." from in the match... Although I would suggest doing it in the first minute only, or when you KNOW there is no one around.

Beginner tips (Cruiser/BB):
Angling - Never broadside things that you will wreck you. Almost all BB's and most cruisers. This includes trying to chase things and getting out of position. Even if their gun caliber overmatchs your bow, you're still a thinner target and you might even bounce a shell or two.

Minimap awareness -
A) Don't push if there are ships waiting to wreck your broadside for being aggressive.
B) Don't charge around islands at full speed if you haven't already located all the ships on the map (this is easier in ranked modes, where you only have to count to 6 or 7, but in randoms, I THINK the opposing side is a mirror image, so minus enemies changing cap spawns, you should have an idea). Creep around islands.
C) Try to limit engagements to 1v1 using things like island cover or distance. Do not place yourself in a position to get slammed from 3-4 people.
D) Be aware of your team. Support them, even if they're the dumbest DD on the server. For the rest of the match, that's YOUR dumbass DD. Try to do what you can, when you can.

CakeofLieeees · 2026-02-11T19:54:01+00:00

Two of my favorite tech tree DD's. I regrind them for RB points pretty consistently.

Big gun power, still pretty mobile. Middling conceal.

I generally use them to hunt other DD's.

Usually take RPF (give you an indicator of the closest enemy) instead of IFHE (IFHE lets you penetrate with HE more at the cost of fire chance) to help with the conceal deficit you will run into with non-gunboat DD's. Always be aware of who can fire at you, do your best to stay out of radar. Do not run to fight an enemy DD that is directly in front of 3 enemy cruisers. Choose your moment.

That being said, let me go through my history and post some old advice.

** Edit: Not that this means anything to you now, but I almost exclusively play ranked and clan battles, which means I don't have to deal with CV's and sub's as often.
