摘要
为研究消能减震技术对装配式钢-混组合主次结构抗震性能的影响,以深圳长圳公共住房及附属工程项目6号楼为依托,采用佳构STRAT有限元软件分析屈曲约束支撑(BRB)和防屈曲钢板剪力墙(BRW)布置在主结构不同高度楼层位置对整体结构的抗震性能影响。结果表明:消能减震构件可大幅提高结构耗能能力,降低结构构件损伤;BRB和BRW设置于结构的中高楼层部位的减震效果优于设置于结构低层位置,在中部楼层和高位楼层同时设置效果更优。
In order to study the influence of energy dissipation and shock technology on the seismic new energy of the prefabricated steel-concrete composite primary and secondary structures,based on the Shenzhen Changzhen project No. 6 building,this paper analyzed the buckling restrained braces( BRB)by using the STRAT finite element software,and researched the buckling restrained steel plate shear wall( BRW) which arranged at different heights of the main structure to affect the seismic performance of the overall structure. The results show that the energy dissipation and shock absorption components can greatly improve the energy dissipation capacity of the structure and reduce the damage of structural members. The damping effect of BRB and BRW on the middle and high floors of the structure is better than that in the lower layer of the structure. It is better to set on the middle floor and the high floor at the same time.
