Abstract
In this paper,taking a large shopping mall as an example,ETABS finite element software was used to simulate and analyze the peri-od ratio,interlayer displacement Angle and shear weight ratio of different steel structures,and compare and analyze the steel consumption and engineering cost.The results show that with the increase of the strength of the material,the stiffness of the structure also decreases,the dis-placement Angle between the layers increases,and the shear weight ratio decreases.Among them,Q345 steel structure used the highest a-mount of steel,Q690 steel structure the lowest;Compared with the steel cost of the Q345 steel structure,the steel cost of the Q460 steel struc-ture is reduced by 7.1%,and the steel cost of the Q690 steel structure is increased by 5.4%.The above research provides support for deter-mining the steel structure with excellent performance and economic cost.关键词
