高层框剪结构抗风设计研究

Study on Wind Resistance Design of High-Rise Frame-Shear Structure

从结构性能和结构位移两方面对高层建筑结构抗风设计进行研究,并对抗风设计中不确定性参数和参数灵敏度进行了分析。以某高层建筑为例,通过有限元软件建模分析,确定了案例项目顶点位移的主要灵敏度变量,构建了高层结构在风荷载作用下的位移响应极限方程,并通过计算确定抗风设计满足结构使用要求。

The wind resistance design of high-rise buildings was studied from two aspects of structural performance and structural displacement,and the uncertainty parameters and parameter sensitivity in wind resistance design were analyzed.Taking a high-rise building as an example,through the finite element software modeling analysis,the main sensitivity variables of the case project vertex displacement are determined,the displacement response limit equation of high-rise structure under wind load is constructed,and the wind resistance design is determined to meet the requirements of the structure.
