The Seismic And Damping Performance Research Of Steel Frame Ribbed Low Yield Point Steel Shear Wall Structure

Ribbed type of low yield point steel plate shear wall is a new type of shear wall,this paper use the finite’ element software of ribbed type low yield point steel shear wall and frame ribbed type of low yield point steel plate shear wall under cyclic load of hysteretic performance are analysis.And the steel frame,ribbed type of low yield point steel plate shear wall structure seismic response analysis of seismic wave input different angles.(1)Using ABAQUS finite element software based on the mixed hardening constitutive model for ribbed low yield point steel plate shear wall has carried on the numerical analysis,and compared with the test results analysis,the analysis results show that the finite element analysis of the calculated results was coincident with the experimental results,the finite element model is effective and can be used in the analysis and research of the steel plate shear wall structure.(2)Set up the steel frame-ribbed steel plate shear wall structure finite element model,the ribbed steel plate shear wall outside th framework of hysteretic performance,failure pattern and the characteristics of energy consumption was analyzed,and the study shows that the ribbed steel plate shear wall not only can greatly improve the structure of the lateral force resistance,is also a kind of damping performance superior wall-beam.(3)Established by using SAP2000 steel frame-ribbed type low yield point steel plate shear wall structure seismic response analysis model,the input of different Angle of seismic wave,seismic response analysis,explore the ribbed type damping performance of low yield point steel plate shear wall,studies the ribbed steel plate shear wall in the structure of the necessity of two-way layout.
