摘要
目前超高层建筑结构风振分析常采用的是规范的简化理论方法和基于风洞试验方法频域方法,随着结构体型的复杂化或周边建筑对风场有明显干扰时,进行结构风振时程分析是更为简单直接有效的方法。本文通过编程实现生成风洞试验中风荷载时程数据并导入有限元分析软件进行结构的时程分析,获得整体结构位移、内力以及加速度时程等重要数据,为规范方法不适用的超高层建筑结构风振响应分析及舒适度评估提供了可行的方法。
Nowadays,simplified theory method from design codes and frequency domain method based on wind tunnel experiment method are widely used. As to the complication of the structures or obvious disturbance of the surrounding buildings to the wind field, time-history analysis of wind-induced vibration is suggested as a more simple, direct and effective method. In this paper, wind-induced vibration response analysis is carried out to the ultrahigh-rise structure of Synonym Haifeng. The important data of the displacement of the integral structure,the internal force, the acceleration time-history and so on are obtained by time-history analysis,which is realized by introducing the wind load time-history data into the finite element analysis software through programming. A feasible method for the wind-induced vibration response analysis and the evaluation of comfort is put forward in this paper for the ultrahigh-rise building structures beyond codes.
