摘要
采用Davenport风速谱,编制了MATLAB计算程序模拟脉动风速时程,并根据规范转换为脉动风荷载,据此建立了时程分析流程,通过分块Lanczos方法进行了模态分析,同时计算了玻璃幕墙的瞬态响应,计算结果可为实际工程设计提供参考。
The simulation program with MATLAB is used to simulate the fluctuating wind based on the Davenport wind velocity spectrum. The fluctuating wind load can be gotten according to the standard. The time history analysis process is established. And then the modal analysis and the time history analysis are done. The results can provide design reference for practical engineering.
