强风作用下沿海框剪结构的风致响应有限元分析

Finite Element Analysis for Wind-induced Response of Coastal Frame-shear Structures under Strong Wind

福建地区处于我国东南沿海季风气候区域,由于直接临海环境和台湾海峡的狭管效应,使得该地区成为强风压带,影响地区建筑结构的风致安全。目前,风致作用已经成为该地区高层柔性结构的控制作用,为了分析强风对建筑结构的影响,本文针对一栋典型的框剪结构进行强风作用响应模拟和分析,得到一些有益的结论为该地区的建筑结构抗风设计提供参考。

Being located at the southeast coastal monsoon climate area in China, Fujian Province is directly facing with seaside environment and narrow tube effect of the Taiwan Strait, which makes it as strong wind pressure zone and affects the wind safety of building structures in this area. Currently, wind- induced effect has played a control part to high- level flexible structures in Fujian Province. Therefore, in this research, to analyze the influence of strong wind on building structures, the simulation and analysis of strong wind - induced response of one classical shear frame building are conducted, and conclusions are obtained to provide references for wind resist design of buildings in this area.
