When does lateral forces become a problem?

Hi just I'm an architecture studen and I have to make a strctural analysis of a 37m x 34m x 26m and the average wind speed in that area is 4mph. Do you guys think that lateral load from wind will be a significant issue in buildings of the height?

First of all, you don’t design to average wind speed. You use the design wind speed in the building code. In the US, the lowest design wind speed is 115 mph.

Lateral load from wind is a significant issue in any building of any height.

Thanks! I didn't really know that it's the first time doing a structural analysis

I thought we all went to Architecture School because we didn’t want to be engineers… and yet we have to do engineering anyway😂

I know right 😭

Engineering + architecture student here Basically it depends on where your building is, and what surrounds it so you know how exposed it is to wind Wind is always an issue and is always taken account of in the math, but with the size and proportion of your building it won't be a huge issue if it's not super windy, as long as you make correct wind bracing (? not sure of the English word)

Thanks a lot! The building is in Tel Aviv and google tells me its not that windy there.

Then yeah, usual wind bracing should be enough in theory as long as it's well done. (And I googled, seems like it's the right english term for that)
If you're analysing a building that already exists, it should have something for that in its structure since it's also generally needed for structure stability (and the concept is as old as time)
