摘要: 提出了一种新颖的平-波钢板剪力墙,研究了其弹性屈曲性能与稳定承载力设计计算方法。平-波钢板剪力墙由平钢板和波形钢板标准单元连接而成,后者在工厂通过自动化生产线加工而成,因而生产效率高。通过大量算例的有限元数值计算,分别研究了焊接连接型与螺栓连接型平-波钢板剪力墙的受剪弹性屈曲模态、弹性屈曲荷载、破坏模式、失稳机理及弹塑性稳定承载力,其中包含不同参数对屈曲与承载力性能的影响,并提出了受剪稳定承载力设计方法。Abstract: This paper proposes a novel flat-corrugated steel plate shear wall (FCSPSW) and explores its elastic buckling performance along with the design and calculation methods for its stability bearing capacity. The FCSPSW is constructed by connecting flat and corrugated steel plate standard units. The latter are fabricated in a factory using a fully available and automatic production line, which ensures high production efficiency. Through the finite element numerical analysis of a large number of examples, the shear elastic buckling modes, elastic buckling loads, failure modes, instability mechanisms, and stability bearing capacity prediction for both welded and bolted connection types of FCSPSWs were studied respectively. This numerical investigation revealed the influence of different design parameters on the buckling and bearing capacity. Finally, design methods for predicting the shear stability bearing capacity of two types of FCSPSWs were proposed.
