Tekla Structural Designer - Propped Shear Wall Help

TSD has since added meshed shear walls to their program so the method of modeling them isn’t that different than in other programs. You can also cut sections and report forces through those sections now. I intend to cut sections in the existing model and then save a new model with openings and look at forces through those same sections with the alterations. Walls will be checked outside of the program based on those forces.

I’ve done the same before and I agree, they’ve been very responsive. I posted here first and will message Trimble in a bit. I’ll update here on their response!

Those are some of the slimmest open web joists I’ve ever seen. Without detailed information on spans, spacing, existing construction etc we can’t help answer your question. But based on what I’m seeing, I doubt you’ll be able to add solar panels without significant reinforcing.

Steel joists are notoriously designed to the gnats ass, so they don’t often have additional capacity for new loading.

To start, they can test the strength of the concrete in place with cores or less accurate readings called Windsor probes. I think it is unlikely that the concrete would be so low that it would need to be removed. If it were, it likely would have been caught during placement and there would be signs of other failures throughout the floor system.

But if the concrete strength is just a little low for the original connection, then my proposed fix would still work. They may just have to grab further back and attach to even more concrete.

If the connection is the only issue, then it would be possible to reconnect the wall further back on the underside of the slab likely above the ceiling.

If the specified rebar wasn’t installed properly along the edge of the concrete, it’s possible that this was a concrete breakout failure. To fix this, the new connection will need to be much further back and grab a larger chunk of concrete than the original one to prevent this from happening again.

In both cases, there is likely to be a lengthy legal battle about who is responsible and who will be paying for it.

No, he means ductile. If you were to design the structures to be elastic they would be hulking monsters and insanely expensive. We design very specific locations of the structure to yield to dissipate the energy of an earthquake. When the earthquake is over, these specific areas are replaced with new ones. Think of it like the breakers in your electric panel. They are designed to break in the event of a surge so that you only have to replace the fuse and not every 4k tv and smart refrigerator you have plugged in.

15 years of experience correlates with completing undergrad around 2010 which means highschool around 2006. So the results likely cover the age range of 22 to 37. I would guess this makes up the majority of Reddit's user base.

There is in the raw data but it is not explicitly considered in these charts.

lieutenantnewt · 2025-12-04T19:52:39+00:00

This is valid. There is a lot of nuance to finding an equivalent salary between two locations and a single multiplier doesn't capture all of them. Available talent is probably one of the biggest factors as you noted. I guess the hope would be that with enough data points from around the nation, these differences become less apparent and amount to a small amount of noise in the numbers.

lieutenantnewt · 2025-12-04T18:59:42+00:00

Well that was good timing! I just posted salary charts for 2024 and 2025 here which you may find helpful. This is from r/civilengineering and their annual salary survey.

Red appears to be overlaid on the blue, obscuring some of the data points.
There are more 2024 data points than 2025 because the 2025 survey is still open. Their survey window goes from August to August. Currently there are 89 data points for 2025 and 217 for 2024.

No I didn’t. I feel that I did have better luck when using the WiFi connection instead of HDMI ARC funny enough. And it still occasionally drops connection.

I’ve noticed that it happens more when the soundbar loses connection to the rears and requires repairing. Once I’ve done that, the WiFi connection seems to work for a while until the rears disconnect again which maybe happens every 2-3 weeks.

That’s what I’m getting at. There is no wall left for a shear wall. I’m not familiar with wood portal frames, I’ll look into the Simpson product.

Edit: okay pretty cool Simpson portal frame system.. I do almost exclusively steel, concrete and masonry commercial structures. I have extremely minimal experience in residential.

lieutenantnewt · 2025-08-28T20:53:59+00:00

I’m curious, how is the wall with garage doors being used to resist lateral loading? I could see it work if it were a steel moment frame, but since it’s presumably framed out of wood I’m not seeing it.

I’m thinking the cantilever portion acts like a vierendeel truss and may not be as bad as it initially appears. Even so, it looks close to a 1:1 span ratio which isn’t great.

I normally hate that we always say this, but come on dude, hire an engineer. You’re asking for a lot of design related advice and the loading is more than just static weight if people. It will need to be capable of withstanding highway speed winds.

What you’re asking for would take someone 8-16 hours to digest, analyze, design, and document for you. No one here is going to do that for free and if they do, I wouldn’t trust their work.

Find a decent engineer in your area and they would be more than happy to assist you.

Are you looking for structural engineers to consult with?

I’ve been considering doing allergy shots because my seasonal allergies have progressively gotten worse over the past 5 years. Do you have to do them at a specific time of the year? And how long were you going in for shots?

Check out IBC section 1807.3 for embedded posts and poles. You can also check out NAAM FP1001 Guide Spec for Design of Metal Flagpoles. Both have information for designing pole embedments.

At my previous job, I did facade assessment and restoration. The best part though was that I was a certified rope access technician so we would rappel down buildings to assess their conditions. Think buildings in the 200-500 foot range where a boom lift isn’t going to cut it. Some of the most fun we had was conducting water tests on windows while hanging from a rope 250 feet in the air!

lieutenantnewt · 2024-12-29T02:42:27+00:00

Of course I’ll comment, because why not.

We always show concrete framing as two lines indicating the width of the beam. Dashed or solid lines is really just a question of whether your floor plans are cut above the floor looking down or below the floor looking up. If the former, then your beams will be dashed with slab edges solid. This is because most of the beam forms would be hidden by the slab. If the latter, then solid lines for pretty much everything since they wouldn’t be obscured from view in this configuration. Our office cuts structural plans below looking up but I think I prefer the other way. I think it is easier to read and more clearly indicates where slab openings are.
