Title: Computer Program for Wind Time-History Load Simulation of Tall Building Structure Under Wind-induced Vibration
Abstract: Wind-induced comfort problems of tall building have raised more and more attention,empirical formulas from design codes and wind tunnel experiment method are widely used nowadays.However,as the complicate structure systems and especial structures with viscous dampers are widely applied,wind load time-history analysis method is more precise.In this paper,auto-regressive method is used to simulate the random wind dynamic loads which consider 3D spatial correlation.The computer program is developed to produce wind load time-history and export to FEM program to carry out the time-history analysis under wind-induced vibration.The program provides feasible method for analysis of wind-induced vibration of tall building structure.The proposed method was applied in numerical simulation of several typical examples.The results verify the effectiveness of this simulation method in practical structural analysis.
