Lateral Behavior And Design Method Of Vertically-corrugated Steel Plate Shear Walls Connected To Beams Only

In order to meet the needs of doors and windows opening in practical engineering scenarios,this paper researches the vertical corrugated steel plate shear walls connected to beams only.Numerical analysis based on the finite element software ABAQUS is carried out to investigate the lateral resistance and hysteresis performance of this corrugated steel plate wall,and to study the interaction and influence of the infill panels with the frame,and then to propose the calculation method and design process of the twosided connected vertical corrugated steel plate shear wall(hereinafter referred to as "corrugated steel plate wall").,in order to provide theoretical support for the design and application of this structural system.First,a single-layer single-span hinged frame model is used to study the lateral resistance of corrugated steel plate shear wall panels.Based on the results of a large number of variable parameter numerical analyses,the vertical corrugated wall panels are classified to reveal their lateral resistance mechanisms,and the wall panels are optimally selected based on their load-bearing capacity and ductility properties.The stiffening members are set on the free edges of the two-side-connected vertical corrugated steel plate shear wall,and the form of the stiffening members is selected and analyzed to obtain the stiffness ratio of the bounding ribs to achieve sufficient stiffening effect.The differences in the performance of wall panels under unidirectional push-over and reciprocating loading is discussed;the optimum selection of the corrugated wall panels considering the ultimate and residual load factors is proposed for direct adoption by designers,using reciprocating loading as a benchmark.Next,the plate-frame interaction problem in the corrugated steel plate shear wall is discussed.First,the distribution and magnitude of the additional forces generated by the embedded wall plate on the frame beam are theoretically derived and analyzed,and the internal force calculation equations and threshold stiffness requirements for the frame beams are proposed and verified by a finite element calculation example.The influence of the connection method between the wall panel stiffening members and the frame beam on the lateral resistance of the wall panel and the internal force of the frame beam is considered.The effect of vertical loads on the structural system is considered and the formulae for calculating the internal forces of the frame column is given.The synergistic lateral resisting effects of the embedded wall panels and the edge frame,the horizontal load-bearing proportion to be borne by the embedded wall panels,and the plastic development sequence of the structure are studied and compared with the flat steel plate shear wall.Finally,the design method and procedure of the two-side-connected vertical corrugated steel plate shear wall structure are proposed based on the above study.By designing an office building with a steel plate shear wall as the structural form,the mechanical properties of the two-side-connected vertical corrugated steel plate shear structure and two-side-connected flat steel plate structure are analyzed using static elastoplastic analysis.
