摘要：

本文以一64m跨度的三心圆柱面网壳干煤棚工程为例，利用SAP2000建模分析，通过综合考虑结构动静力特点与防屈曲支撑（BRB）特点选择了六种BRB布置方案。对比分析地震作用下几种方案的结构内力及节点位移，得出将防屈曲支撑布置在内力较大的上弦杆处能够有效减小地震作用下结构的杆件最大轴力，将防屈曲支撑布置在受力较大的腹杆处时能够有效减小地震作用下结构的各向节点最大位移。为三心圆柱面网壳的减震控制研究提供参考。

Abstract:

This paper mainly takes a 64m span of three centre cylindrical latticed shell project for example, by using and analyzing SAP2000 to consider the structural characteristics of dynamic and static forces and BRB features choosing from six BRB layout scheme. After comparing and analyzing the structure of internal forces and displacements of several options node, we draw a conclusion that when BRB are arranged at the top chord of the rod, it can effectively reduce the maximum axial force structures under earthquake, while when BRB are arranged in a large abdominal force, it can effectively reduce the nodal displacements under seismic structure.It provides reference for controlling vibration damping of the three centre cylindrical latticed shell .
