Research On Low-yield Steel Plate Shear Wall Structure Major:Structural Engineering

In this paper,multi-ribbed low-yield steel shear wall(MLSSW)was studied in following aspects by experiment and simulation,based on that structures with steel frame was simulated.There are some research content as follows:(1)Double frames of specimens by MLSSW under pseudo static tests and there specimens’failure mode,force performance,hysteresis energy,stiffness degradation and energy dissipation capacities were analysed as well as do some research on seismic behavior.(2)ABAQUS finite element analysis software used to establish the calculation models of MLSSW,and hysteresis curve,skeleton curve,stress cloud diagram,strain cloud map and PEEQ map were simulated.By comparing with experimental results,it is shows that finite element model of steel frame-MLSSW has well applicability,which lays a foundation for the further studies.(3)In the light of finite element software of ABAQUS,steel frame-MLSSW,structures’model were established and hysteretic behavior,energy dissipation capacity,energy dissipation mechanism and failure modes were researched.This investigation notes that MLSSW not only has a great increment of structure’s side resistance and bearing capacities but also plays a major role in lateral force and energy dissipation performance.
