摘要
在频域内,对马鞍型体育馆结构考虑了多阶振型的影响,由结构风振动力的振型分解法,进行了该体育馆前20阶振型和振型耦合后风振动位移响应的分析和研究,得到了结构的模态特性及风振动响应,并根据本文定义的位移风振系数,对此结构提出了工程设计需求的风振系数。
In frequency domain, contribution of the higher mode shapes to wind-induced vibration response must be included in the dynamic analysis of the saddle-shaped gymnasium structure. Using the SRSS method the dynamic response considering the effect of the first twenty modes was analyzed, and mode shapes and dynamic response of the structure were obtained. In addition, the wind-induced vibration coefficient was provided for project design according to the definition of displacement wind-induced vibration coefficient in the paper.
