【摘要】：对一榀单跨两层半刚性框架-密肋网格复合钢板剪力墙结构进行了低周反复荷载作用下的试验研究。系统分析了结构的受力机制、破坏模式和耗能机理,得到了承载力、刚度、延性及耗能能力等指标,评价了该种结构体系的抗震性能。结果表明:结构在弹性工作阶段主要依靠墙板的剪切机制承担水平荷载,非弹性阶段区格中钢板的对角拉力带为结构提供侧向承载能力;密肋网格的设置有效限制了内嵌钢板的面外变形值,提高了结构的弹性刚度,克服了滞回曲线的"捏缩"效应,减小了钢板的噪音及震颤,显著增强了结构的耗能能力;框架与钢板墙协同工作良好,结构塑性变形能力强,安全储备高,是一种优良的抗侧力体系;破坏模式为各区格中的钢板撕裂,拉力带效应明显,边框架柱脚及边框架梁端形成塑性铰。
[Abstract]:An experimental study of a single-span two-story semi-rigid frame-multi-ribbed composite steel plate shear wall structure under low cyclic cyclic loading is carried out. The mechanism of stress, failure mode and energy dissipation of the structure are systematically analyzed. The bearing capacity, stiffness, ductility and energy dissipation capacity are obtained, and the seismic performance of the structure is evaluated. The results show that the horizontal load of the structure mainly depends on the shear mechanism of the wall plate in the elastic working stage. The diagonal tensile belt of steel plate in inelastic zone provides lateral bearing capacity for the structure. The setting of multi-ribbed mesh can effectively limit the out-of-plane deformation value of embedded steel plate, improve the elastic stiffness of the structure, overcome the "pinch" effect of hysteretic curve, and reduce the noise and tremor of the plate. The energy dissipation capacity of the structure is greatly enhanced. The frame and the steel plate wall work well together, the structure plastic deformation ability is strong, the safety reserve is high, is one kind of fine side force resistance system; The failure mode is the tearing of steel plate in each grid, the effect of tensile band is obvious, and the plastic hinge is formed at the foot of the edge frame column and the end of the edge frame beam.

【正文快照】： 0引言钢板剪力墙结构逐渐成为现代结构的主要抗侧力体系[1-2]。国内外大量低周反复荷载试验和振动台试验研究表明,钢板剪力墙结构具有较高的初始刚度,延性好,耗能能力强,是抗震性能非常优良的抗侧力体系[3-6]。直到上世纪80年代,钢板剪力墙结构仍以内嵌钢板的面外屈曲作为极限
