Research on seismic performance of prefabricated shear wall with opening connected by semi-dry connection
A prefabricated shear wall with opening connected by semi-dry connection formed by the combination of bolted dry connection and post-pouring belt was proposed.By establishing the finite element model of cast-in-place and prefabricated composite shear wall with openings of the same size,and comparing and analyzing the simulation results of the two values,the feasibility and reliability of the semi-dry connection method were verified.Furthermore,the variable parameter simulation of the prefabricated shear wall with opening connected by semi-dry connection was carried out.By analyzing the simulation results;it is found that the increase of the opening rate of the hole will reduce the overall performance of the wall.The eccentricity rate of openings,the axial compression ratio and the aspect ratio have a significant effect on the bearing performance,lateral stiffness and ductility of the wall.The eccentricity rate of openings and the aspect ratio should not be too large,and the axial compression ratio should be controlled in an appropriate range.
