摘要
钢结构具有抗震性能好、施工进度快、易于产业化、绿色可回收等特点,在高层建筑与大跨度空间结构中获得广泛应用。基于此,本文分析了钢框架结构的结构扭转破坏机理,并通过多层钢框架结构进行PKPM建模,分析不同结构平面布置方案下相应结构扭转效应。研究发现,将抗侧力构件、抗侧刚度大的构件尽量布置在结构边缘的最优平面结构布置方案,有利于节约工程造价,降低扭转对结构的破坏作用。
Steel structures have the characteristics of good seismic performance,fast construction progress,easy industrialization,and green recyclability,and have been widely used in high-rise buildings and large-span spatial structures.Based on this,this article analyzes the structural torsional failure mechanism of steel frame structures and conducts PKPM modeling through multi-layer steel frame structures to analyze the corresponding structural torsional effects under different structural layout schemes.Research has found that arranging anti lateral force components and components with high anti lateral stiffness as much as possible at the edge of the structure in the optimal planar structure layout scheme is beneficial for saving engineering costs and reducing the destructive effect of torsion on the structure.
