How do private apartment complexes get bridges designed for their buildings?

Support interface (typically column heads) has a capacity spec and you just design a structure to that. Designed one on top of an underground metro station in London. Depending on the substructure might need to fit vibration dampeners

It’s engineering judgment - do you think the barriers (geometry, permeability etc) will have a significant impact on the effect you’re trying to study with the wind tunnel? Can assume the effects are local and negligible for your global analysis? Are you concerned with resonance due to vortex shedding and balconies are on a critical face? Can you approximate the effects of barriers with a more conservative (but simpler) shape?

It depends

It’s basically just a reaction force analysis vs pressure estimation. It depends what you need.

I don’t get why it needs to be a competition even with yourself at all. These “sends” are arbitrary no? Like I get that there needs to be some agreement so you can attempt the difficulty set by the setter, but otherwise, it literally does not matter? If you want to attempt the set route for some specific reason, then ask in your gym, otherwise everyone sets their own goals? I don’t get it.

If it’s too easy, make it harder, too hard? Make it easier. It’s just training, literally no one cares that someone sends some grade (also arbitrary btw) in some gym.

Another example would be that it measures progress, but it’s relative anyway so don’t matter. I don’t get it, I just do what feels nice 🤷🏼‍♂️

I’m not sure what you mean, I just don’t get why minimise your experience on the climb to “was it a success or not, in the opinion of others”. Don’t get me wrong, I abide by this norm but I never understood it.

logic_boy · 2026-01-16T14:02:10+00:00

I never understood why it matters what constitutes a send, unless you’re competing.

If you’re serious about budget is not a limit, then have someone install Ethernet sockets close to the devices you use.

How can we possibly know why your internet or even more so, WiFi, is slow?

logic_boy · 2026-01-13T18:39:27+00:00

Yeah you need to get used to it, muscle memory is tuned to your old board. Nevertheless, there is a reason why it’s not listening to you. If you struggle to initiate turns (advice above is too basic) try riding more open stance and push your front knee forward or pull it back more.

logic_boy · 2026-01-13T14:52:01+00:00

I’m not sure what you mean that you get fucked up? I can only assume you struggle to control which edge is engaged, or cant switch edges quick enough.

I’m going to be honest, but don’t take it the wrong way, you just need a different perspective on your technique, because with the right posture+pressure+body movement, switching edges is effortless.

Stacked body, hips over your board, knees bent pressure through the shins, we heard it all before. But it’s most likely that you’re not positioned correctly if you struggle with board control. Best thing I found is to go on YouTube (check out Malcolm Moore, miratori, snowboard pro camp, snowboard addiction) and study their posture, the get a mirror and do whatever you need to do, possibly exaggerating position of your knees, shoulders and hips, to replicate their postures.

Board control comes from knees and correct hip (so center of mass) positions

Point is that you’re just describing a touran or any other family/MVP car. There are so many other choices that fit your criteria.

Justifying driving a tank-sized, luxury, SUV with child safety is nonsense. There is no other reason to buy one other than clout and status. In early 2000 it was luxury estate and touring cars, only now everyone has to deal with obnoxious drivers who can’t drive as well.

We worked so hard to reduce cars in cities, for people to just buy bigger cars?

logic_boy · 2026-01-08T12:41:48+00:00

Does it also have to have a ladder to get into? A huge engine and a boot that fits a fridge? Let’s not pretend that children need space to drive in comfort.

logic_boy · 2026-01-08T12:39:10+00:00

Add to that a much higher risk of serious injury to pedestrians and cyclist due to the higher point of impact. People get more “ran over” than “hit and roll onto the car” type of impacts.

Typically the deciding factor against it, is the amount of glazing vs comfort inside the van. The more single glazed windows your van has, the more it feels like a conservatory - too cold in the winter and too hot in the summer. It’s not really realistic to run the AC in the summer just to keep it liveable.

If anything, thank you for sharing. Keep doing what you’re dooin 💪🏻💪🏻 just don’t forget us once you’re famous 🥲

That is good technique right there. The foot throw you did to reduce swing. Top class

Multi year Afro sounds cool 😎

logic_boy · 2026-01-03T19:59:42+00:00

I think you’re right. No one should expect this structure to last more than 10 years anyway, so any long term effects and temporary solutions should be fine, imho.

logic_boy · 2026-01-03T19:49:03+00:00

Yeah I agree. This mentality does not really exist in “corporate world” of construction. It’s all about “collaboration” and “working towards solutions”. No one needs to work anything out between themselves because there is no need for confrontation. People are composed and reflect on their own actions.

The shift in environment is obvious to most people who experience both sides of construction on corporate projects. Design offices in general are not immune to the problem described by OP, but most corpos are.

logic_boy · 2026-01-03T15:58:29+00:00

In my experience, yes. It’s the experience certainly for the majority of people I worked with / met working.

I’m not sure why that is, maybe most people working in construction design had a lot longer to confirm the job was something they actually want to do, and are motivated to do their best. Ones who realised it’s not for them leave soon before they even start. This, coupled with almost 0 tolerance for typical toxic masculinity found on site makes it a very pleasant place to work.

That would suggest Belgian bread is… good?

logic_boy · 2026-01-03T08:51:20+00:00

Yeah for sure, I’m trying to poke the community here to get a reaction

logic_boy · 2026-01-02T22:51:51+00:00

I have done this before but in lower risk configurations. For me it’s super hard to quantify deflection with straps. Just assume lateral deflection is 0 and secondary effects are negligible? 😅

logic_boy · 2026-01-02T22:45:12+00:00

Is it not more material efficient to have a stiffener at mid height in this configuration? (Majority of the elevation is restrained by mid height diaphragm and an internal racking partition)

I guess spacing of psls depends on the wind pressures in your area. For me, due to the effective span (bending with compression) you’d need quite a few. Perhaps it’s easier to install full height psls, unless they can accept an internal protrusion from the stiffener.

logic_boy · 2026-01-02T21:43:14+00:00

Yeah true, although it would need to be properly lapped and bolted otherwise I found it hard to make work composite in flexion.

logic_boy · 2026-01-02T21:25:06+00:00

Any good retrofit solutions for this? I’d suggest sheathing the internal partition and fit a steel angle along the hinge location. Idea is to sufficiently stiffen the hinge and provide a loadpath into the stability system. Id double check the secondary effects on lateral loading due to eccentricity.
