错列钢桁架结构考虑填充墙影响的设计要点

对错列钢桁架结构在地震力组合荷载作用下进行了是否考虑填充墙刚度影响的有限元对比分析,得出由于错列钢桁架结构比较其他结构形式的杆件截面较小,填充墙刚度对结构及杆件受力性能的影响比较明显,并给出了考虑填充墙影响的周期调整系数及在错列钢桁架结构设计中考虑填充墙影响需要加强的有关杆件的建议,以指导实践。

Design points of staggered steel truss structure with the impact of filled-wall taken into consideration

This paper carries out finite element comparison analysis on the rigid impact of filled-wall for staggered steel truss structure under seismic composite load,and finds out that impact of filled-wall rigidity upon the structure and bar stress performance is comparatively obvious owning to the small bar section of staggered steel truss structure comparing to other structures,and then proposes some suggestions,such as taking the cycle adjustment coefficient of filled-wall impacting into consideration,strengthening relevant bars while taking the impacts of filled-wall into consideration,with a view to guide practice.
