High-rise Lateral Resisting Systems

High-rise Lateral Resisting Systems

High-rise Lateral Resisting Systems

(OP)
Hi All

Can someone prescribe literature for high rise
lateral load resisting systems in terms of analysis
and design?

Kind regards

RE: High-rise Lateral Resisting Systems

I feel like your asking for some medicine.

First of all there are many different systems for hights. https://www.britannica.com/technology/structural-e...

Google maybe your best friend until your figure out the real question

"Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning."

RE: High-rise Lateral Resisting Systems

That's a pretty broad question. Steel, concrete? Generally speaking the concepts are the same as low rise but it gets harder and harder to control drift (height^2) so moment frames are usually out except maybe a dual system. As you get taller you'll want to engage more and more of your overall building - both to increase your 'd' and to counteract tension. This is typically done via outriggers, coupling beams, or both. If it's concrete you also need to pay more attention to cracking of the walls and outrigger elements. Above maybe 30 stories you'd want to start looking at building accelerations (and column shortening).

Stiffening the bottom of the building is your friend, minimizing that base rotation has an outsized affect because of the amplified affect way up a the top stories.

Apologies, let me be more specific.

We are currently busy with the design of a concrete apartment block
going 17 stories high +/- 50 meters. We have concrete shear walls and
and of course our lift shaft and stair core for lateral stability.

I have run a couple of models but I want to get some proper background especially
on the effects it will have on my slab and more importantly on my foundation inter-action.

I realise it is not that heigh and it is not in a seismic zone. Only lateral loads will be the wind.

Kind regards

Always find these kind of thread really scary !

It sounds to me as though you may be interested in the backstay effect. If so, check this stuff out:

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: High-rise Lateral Resisting Systems

That NEHRP reference is great, just unfortunate it doesn't subscribe to the metric system!

RE: High-rise Lateral Resisting Systems

Can you take the lateral loads out in stairwells? or elevator shaft? in direction at right angles to the shear walls? 17 stories is not overly tall. Do you have parking below?

Thanks Kookt.
This is exactly what I was looking for!
