Statistical analysis of the response spectra due to both horizontal and vertical ground excitations is conducted. A method is presented for generating a uniform hazard response spectrum making use of the seismic hazard curve expressing annual probability of exceedance as a function of peak ground acceleration (PGA), a set of normalized mean response spectra, and a coefficient-of-variation function...
A response spectrum method is proposed for the seismic analysis of a multisupport structure subjected to spatially varying ground motion. Based on theoretical results by Der Kiureghian and Hofer, an approximate and efficient analysis of the frequency integral of the cross-correlation function of multisupport excitation is presented. A two-span beam-like structure is studied to demonstrate the application...
