Abstract:
To realize structure's reparability after being damaged by earthquakes,a reparable precast shear wall with horizontal steel connections(RPW-HSC)was proposed.The finite element model of RPW-HSC with the height-width ratio of 1.0 was established based on ABAQUS,the numerical simulation was in good agreement with the experimental results.The effects of the shear-plate thickness of steel connection,the height-width ratio of small steel column at the slit,the steel-plate strength and the axial compression ratio on the shear performance of specimen RPW-HSC were investigated by finite element parametric modeling,and the design method of shear-resistance bearing capacity of RPW-HSC was established.It's found that the stiffness and shear-resistance bearing capacity of specimen RPW-HSC increased with the increase of shearing plate thickness,steel strength and axial compression ratio.However,excessive parameters caused the failure of the specimen changing from steel shearing plate damage to upper precast concrete wall damage.When the height-width ratio of the small steel column at the slit was less than 3,the failure of the specimen changed from the bending failure of the small steel column at the slit to the shear failure of the upper precast concrete wall.Therefore,it was necessary to control the reasonable design parameters to realize the controllable structural damage and earthquake-damage reparability of the specimen RPW-HSC.The theoretically calculated values obtained from the shear-resistance bearing capacity design method of the specimen RPW-HSC were in good agreement with the test values and finite element results,which verified the accuracy of the shear load capacity design method.
