Abstract:

In this paper, according to the principle of linear auto-regressive model (AR Model). a time-history simulation program of wind velocity is proposed for large-span spatial structures. and the feasibility of the ProIposed program is verified by a practical example. The simulated wind vibmtion loads are then applied to the time-history analysis of wind vibration response of single-layer spherical latticed shells by the finite-element program ANSYS.Through comparing the results obtained by the time-history analysis with the computational ones obtained by the fre-quency-domain method. it is found that the results of the time-history analysis are agreement with ones of the fre-quency-domain analysis on the whole. But the peak values of the time-history response are far exceed those of the static-wind response , and the wind-vibration coefficient of the frequency-domain method is bigger slightly that of the time-domain method.

Key words: spherical latticed shell, wind vibration response, time-history analysis, frequency-domain method
