| Abstract |
The purpose of this study is to propose the optimal distance of input load for efficient time history analysis on tall buildings. For the purpose of this study, fluctuating wind force for time history analysis are simulated by the one-dimensional multi-variate spectral representation method using Karman spectrum about along-wind direction and Liang spectrum about across-wind direction. Through comparison between the simulated and target spectrum of the wind field, this technique has been proved to be efficient and reliable. Optimal applied load distance is verified by comparing top acceleration standard deviation values obtained from time history analysis with those of wind tunnel test for the selected buildings models. |
