Abstract: To study the calculation method of lateral stiffness and horizontal bearing capacity of prefabricated coupled shearwall with precast concrete (PC) infill wall, the low-cyclic loads tests of one specimen without infill wall and two specimenswith PC infill wall were completed, and the effects of PC infill wall on lateral stiffness and horizontal bearing capacity ofprefabricated coupled shear wall were investigated. Based on the tests, a simplified structural analysis model wasinvestigated. The calculation method of lateral stiffness and horizontal bearing capacity of coupled shear wall was proposed.The results show that the integrity of the prefabricated coupled shear wall with PC infill wall is good, the existence of PCinfill wall can improve the lateral stiffness and horizontal bearing capacity of the specimen. The connection form of PC infillwall and coupled shear wall has a great influence on the lateral stiffness and horizontal bearing capacity of the specimen;Based on the continuous calculation method, the anti-side stiffness and horizontal bearing capacity of the prefabricatedcoupled shear wall with PC infill wall is proposed by the continuous calculation method, and the calculation results are goodwith the experimental value.

Keywords:prefabricated coupled shear wall; precast concrete infill wall; flexible connection; rigid connection; lateralstiffness; horizontal bearing capacity
