Study On Seismic Behavior And Energy Dissipation Of Multi-ribbed Low Yield Point Steel Plate Shear Wall

Multi-ribbed low yield point steel plate shear wall is a new type of anti lateral force structure.The three specimens of multi-ribbed low yield point steel plate shear wall were experimental and theoretical study,the main research contents:(1)Based on the pseudo-static testing on three specimens of 1:2 scale model of multi-ribbed low yield point steel plate shear wall to study the bearing capacity,stiffness,ductility,energy dissipation capacity of multi-ribbed low yield point steel plate shear wall,discusses the failure mode,hysteretic behavior and energy dissipation mechanism of this new type of wall The test results show that the multi-ribbed low yield point steel plate shear wall is a kind of lateral force structure with excellent seismic performance.(2)The nonlinear seismic response analysis of steel frame-multi-ribbed low yield point steel plate shear wall structures are carried out by SAP2000,and study response of the maximum top displacement,maximal interlaminar displacement angle,maximum story shear,maximum acceleration and maximum inter layer velocity of the structure of steel frame-multi-ribbed low yield point steel plate shear wall under three kinds of earthquake waves,discusses energy dissipation effect of different kinds of multi-ribbed low yield point steel plate shear wall.The calculation results show that the three kinds of the multi-ribbed low yield plate shear wall have obvious damping effect,and structure of multi-ribbed low yield point steel plate shear wall is a kind of vibration reduction structure with excellent energy dissipation effect.
