Abstract
In this paper,the failure mode,stiffness curve,ductility coefficient and energy dissipation performance of new prefabricated masonry structure are analyzed by static loading test.The results show that the structural strength of T-shaped section prefabricated masonry is better than that of unfilled prefabricated masonry of a straight section,and the mechanical properties of prefabricated masonry can be effectively im-proved by applying prestress to the rebar.The application of prestress can effectively improve its ductility and bearing capacity,and the T-shaped section has good bearing capacity and ductility.The energy dissipation coefficient of the unfilled prefabricated masonry structure with T-shaped section is 0.62,which decreases by 5.3%after the prestress is applied.The energy dissipation coefficient of the unfilled prefabrica-ted masonry structure with T-shaped section is 0.82,which decreases by 11.5%after applying prestress.The application of prestress can slightly strengthen the energy dissipation performance of the prefabricated masonry structure with a straight section,but weaken the energy dis-sipationperformance of the prefabricated masonry structure with a T section.关键词
