Re: Vertical component of EQ in UBC97 and IBC2000

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There was some research on in-structure vertical response for non-structural components on some failed components. The demand greatly exceeded the capacity.

On one such structure, I noted an acceleration due to the response of the structure was an increase by a factor of 4 over the free field vertical ground motions.
One other thing. Has anyone looked at the structure frequencies and compared them with response spectra of the vertical motion?
