Experimental study on lateral force resistance of buckling restrained steel plate shear wall with two-side connected wood cover plate
From the angle of environmental protection,a kind of steel and wood combined form was put forward,which connects the two sides of anti-buckling steel plate shear wall.Based on the existing research results,two specimens were designed,one was a sheet-plate shear wall without the restriction of wood cover plate,the other was a sheet-plate shear wall covered with wood as the restriction of external buckling of steel plate.The hysteretic curves of the specimens of specimens were obtained through the pseudo-static test with displacement controlled loading method.Based on the test results,the skeleton curve,stiffness degradation and energy dissipation capacity were analyzed.The test results show that the wood cover plate has a better effect on suppressing the buckling of the steel plate,and can effectively reduce the sound of buckling.Compared with the specimens without wood cover plate,the specimens with wood cover plate has higher bearing capacity and stronger energy dissipation capacity.After the specimen was destroyed,the specimen was disassembled,and it was found that the area covered by the wood cover plate in the belly of the steel plate could keep flat,and the removed wood cover plate could also keep intact after loading.The finite element analysis was carried out by software ABAQUS,and the simulation results are consistent with the experimental results,which verify the feasibility of the model.
