摘要:
为研究半刚性框架与钢板剪力墙结构内嵌墙板间的相互作用性能,完成了一榀1∶3比例单跨3层半刚性框架钢板剪力墙结构低周反复荷载试验研究。获得了结构的抗震性能和破坏模式,探究了框架梁、柱、墙板及梁柱节点的局部力学性能,分析了结构的破坏顺序和构件间的传力机理。研究结果表明:该结构具有良好的塑性变形能力和抗震性能,半刚性框架和墙板协同工作良好,结构安全储备较高。内嵌墙板的设置缓解了节点区自身的延性要求,框架承担95%以上的倾覆弯矩,水平荷载由双重抗侧力体系承担,内嵌墙板作为主要抗侧力构件承担约75%剪力。试件整体面内呈弯曲破坏,但是后期钢框架柱面外弯扭较大。通过有限元分析,研究了柱柔度系数、钢板高厚比和梁柱连接特性对钢板剪力墙结构性能的影响。框架梁柱连接刚度对结构体系承载能力的影响与柱的刚度和内嵌墙板的厚度有关。这种影响随着柱刚度增加和内嵌墙板厚度减小而增大。柱的柔度系数为2.5时,柱整体无明显的内凹变形,此时梁柱节点铰接连接更改为刚性连接时,试件承载能力增加小于10%。
Abstract:
In order to study the interactive effects between the semi-rigid frame and the infill plates, three-story single bay specimens of semi-rigid composite steel frame with steel plate shear wall were tested under low cyclic loading. Structure seismic performance and failure mode are obtained. The paper explored the framework of beams, columns, semi-rigid nodes in the local mechanical properties, analyzed the load transfer mechanism and the components failure sequence. The results showed that the specimen have great plastic deformation capacity and good energy dissipation capacity. The frame and the steel plate shear wall work well, the specimen have high safety margin. The requirement of ductility was lowered by arranging infill plates. More than 95% of the overturning moment were undertake by frame. Infill plates as the main component to resist lateral force can bear about 75% of the shear. The whole specimen of the test in-plane bending, but the out-plane bending deformation of the steel columns are large. Through finite element analysis, the influence of connection stiffness on load carrying capacity is related to the stiffness of column and thickness of the infill plate. This influence is enlarged when increasing the stiffness of the column and reducing the thickness of the infill plate.For the specimens with a flexibility coefficient of column of 2.5, the load carrying capacity was enhanced by about 10% when changing pinned connections to rigid connections.
