Designing a high-rise building.
Designing a high-rise building.
(OP)
I’d like to hear especially from those who have experience in designing high-rise buildings. We are going to design a 26-story high building. It is our first of this size. What are the most significant considerations that we have to keep in mind? We have not decided yet the type of lateral resistant system that we will use. How difficult is such a project for the first time, if any?…etc.
Thanks






RE: Designing a high-rise building.
1. What is the occupancy? Condo? Office?
2. Is there a strong preference to concrete or steel?
3. Will the building be in an area with high spectral accelerations?
4. Will the building be in an area with high winds?
5. Are you in an area of poor or good soil/rock?

1) inter-story and total drift.
2) overturning uplift force on base connections.
3) base shear (due to wind / earthquake).
4) Small planes.

I definitely don't intend disrespect to the original poster (because I've been there...) but I can't help but wonder if surgical message boards contain analogous questions like: "I've performed minor surgery for 10 years and just landed a brain surgery that I have to perform soon. Any advice?"
Kinda puts the whole structural engineer vs surgeon payscales into perspective. I won't be complaining about that any more!
I like the idea of hiring a consultant to help you with this project. Somebody could get you going pretty quickly and check your work. I think you owe it to the public.

Well, Engineers and brain surgeons are incomparable. That is why a 10-year experienced engineer is paid only a fraction of what a new graduate brain surgeon is paid.
Four thousand years ago Man built pyramids, towers, bridges, and all kinds of structures relying on basic engineering concepts and principles. Those structures are sometimes of complexity more than a 26-story building.
In the thirties of the last century, engineers built skyscrapers without having computers, sophisticated software, absolutely no wind tunnels, and not even calculators. They basically relied on the principles and basic concepts of engineering.
As to our 26-brain surgery, I mean storey building , we are intending to hire a consultant to get help.

I didn't mean it to sting, really. I was trying to make a general comment about the way things are done, not slam you or your firm. I should've thought more about how it would affect you personally and not typed it.
Again. I am sorry that it came off in a hurtful way. I thought it would be interesting but it wasn't worth it.

...I think a pile of rocks (i.e. the pyramid) is a lot safer and in addition, pharoah could simply kill any lawyer that got in his way.

26 storeys probably is, but we looked at a 15 storey building and the specialists we consulted did not class that as high rise.

Ciao.

In FrustEng's defense, there's a big difference between "I've been designing sheds for 10 years and just landed this 26-story high-rise" and "I've been designing 10-story buildings for 10 years and just landed this 26-story high-rise".

RE: Designing a high-rise building.
For the sake of argument - I'm not sure I agree. Throw a lot of stone/steel/concrete at it may not be the best approach but I still see this kind of designing on a regular basis. I may even admit to following that ethos myself on occasion...
Sometimes clients wnat so much flexibility that the more typical rational analysis process breaks down.
I don't see it very often of the larger projects and would agree that it would be an especially inappropriate technique for this high rise.
