模块化装配式结构是目前高层建筑新兴的高效施工方法,而风荷载是影响高层建筑安全的主要因素.文中针对模块化装配式建筑结构在风荷载作用下的响应进行分析,结合装配式建筑结构模型,明确了高层建筑关键节点位移响应振型和位移进行特征.结果表明,风荷载作用下装配式结构振动周期最大值为1.67 s,变形方向主要在风荷载施加方向,且位移变化范围为-24.82～29.48 mm.
Structural Response Analysis of Modular Prefabricated Building Under Wind Load
Modular prefabricated structure is a new efficient construction scheme for high-rise buildings,and wind load is the main factor af-fecting the safety of high-rise buildings.This paper analyzes the response of modular prefabricated building structures under wind loads.Based on the prefabricated building structure model,the displacement response modes and displacement characteristics of key nodes of high-rise buildings are defined.The results show that the maximum vibration period of the prefabricated structure under wind load is 1.67 s,the deform-ation direction is mainly in the direction of wind load application,and the displacement varies from-24.82 to 29.48 mm.
