内嵌VV-SPSW平面钢框架结构抗震性能研究
|
摘要
对3个内嵌竖向连接竖向加劲钢板墙(VV-SPSW)平面钢框架结构进行了缩尺拟静力试验和有限元分析,通过对多项力学性能指标的数据比较,系统研究了这种平面结构的抗震性能和破坏规律。研究表明:该结构体系在水平荷载作用下具备良好的耗能能力、变形能力以及必要的抗震承载力,抗震性能优良;内嵌的VV-SPSW可作为该结构体系的第1道抗震防线,经合理设计的该平面钢框架体系的破坏规律符合多道抗震防线的设计思想以及"强框架,弱墙板"、"强柱弱梁"的抗震概念设计要求,是一种适合于高烈度地震区的新型抗侧力系统。
A scaled quasi-static test and finite element analysis were conducted for three embedded vertically stiffened and vertically connected steel plate shear wall structures(VV-SPSW) with a planar steel frame structure.The seismic performance and damage accumulation of the planar structure were systematically investigated through the comparison of several mechanical performance indicators. The study shows that the structural system has the necessary lateral strength, good energy-dissipating capacity and deformation capacity under horizontal loads. It has good seismic performance. In reasonably designed planar steel frame structures with embedded VV-SPSW, the latter can be the first seismic fortification line. The damage accumulation of the integrated structure fully complies with the design ideology of multiple seismic fortification lines and the seismic design requirements of "strong frame-weak wall" and "strong column-weak beam" concepts. It is a new type of lateral force-resisting system suitable for high seismicity areas.
