Study On Energy Dissipation And Damping Control Of Multi-ribbed Low Yield Point Steel Shear Wall

In this paper,the seismic behavior of multi-ribbed low yield point steel shear wall have been studied through experimental study.The author used IDARC program for multi-ribbed slab structure with low yield point steel on the nonlinear seismic response analysis,analysed the effect of energy dissipation and damping control of low yield point steel,The main contents are as follows:1.By analyzing two multi-ribbed low yield point steel shear wall in one-second-scale model with quasi static test,the author explored the bearing capacity,stiffness,ductility and hysteretic energy dissipation capacity of them under low reversed cyclic loading,analysed the energy dissipation mechanisms and failure mode.The author analyzed the influence on hysteretic effect of multi-ribbed low yield point steel shear wall in different ways of connection.2.Established analysis models of multi-ribbed slab structure with low yield points steel,using finite element analysis program IDARC for nonlinear seismic response analysis of the structural model with low yield point steel ribbed composite wall and multi-ribbed low yield point steel shear wall.Investigated the effects of energy dissipation and damping control of each models in different energy dissipation devices.
