Estimation of spatial correlation for seismic design of buildings

摘要

The paper discusses a solution for the probabilistic problem of high-rise buildings oscillation exposed to seismic loads in form of a six-component random vector.Two groups of matrices for the dynamic response factors to help estimate the effects of spatial correlation between generalized coordinates and correlation in the various seismic vector components on design stresses in load-bearing building structures have been obtained.The spatial model of a building configured as a thin-wall compound bar provides a solution for the probabilistic problem in analytical form.
