半刚接框架-非加劲钢板墙体系抗震试验研究
|
摘要
半刚接钢框架-内填非加劲薄钢板剪力墙结构是一种新型结构形式,它弥补了传统抗弯钢框架侧向刚度不足的缺点,为采用更加经济的半刚性节点提供了可能,目前国内外对该新型结构体系性能研究属刚起步阶段,因此对该结构体系的研究具有重要的理论和实际意义。文中对一榀两层单跨梁柱平齐端板连接半刚性框架-内填非加劲薄钢板剪力墙结构进行了低周往复循环加载拟静力试验,在试验中,试件破坏过程缓慢,钢板墙拉力带充分发育,试验得出的滞回环饱满,表明该新型结构体系具有优异的抗震性能,从而为今后对该新型结构体系做更深入的分析研究打下了良好基础。
A semi-rigid steel framenon-stiffened thin steel plate shear wall is a new type of structural system which increases the lateral stiffness of traditional moment resistant steel frame,so that this new type of structure provides the opportunity to use semi rigid connection which is more economical.Currently,international and domestic research of the new type of structural system is still in the primary stage,and the study on the structural system is of great theoretical and realistic significant.The experimental research on a two-story single bay specimen of the semi-rigid steel framenon-stiffened thin steel plate shear wall under low frequency cyclic reversed lateral loads has been completed.During the test,the destruction of the specimen is slow,the tension field of the steel plate is fully developed,the hysteretic loop of the specimen becomes full and stable.The tested tesult shows that the new type of structural system has excellent seismic performance,so that the test has laid a good foundation for doing more in-depth analysis and study on the new type of structural system in the future.
