challenges of designing tall structures
guys, inspired by my last thread about designing a tall steel stairway tower, i thought of starting a new thread.
as wind loads on tall structures become very critical, what aspects do engineers look into when they design tall skyscrapers/towers etc. (the commercial ones that we see around) i have the following observations:
---- i am sure they rest the column bottoms on a mat foundation.
---- are there any special aspects of designing the bolts and base plates, if any.
---- how do they manage to keep the drifts at upper stories under allowable limits.
chandan - a book recommendation: "engineering architecture: the vision of fazlur r. khan" a biography of the original tall building engineer. enough engineering nerd-it-dum to keep me intrigued.
wow, that seems to be an exciting book. does it have engineering calculations for design of such structures.
no, its a biography not a how too book but it talks about many of the challenges in design and construction of the hancock building, sears tower, shell building (houston) and a few others. i thought it an interesting read.
many foundations go to bedrock.
i sure wouldn't try one without the help of an old seasoned engineer known for doing this type of work.
