摘　　要：为研究硅酸钙复合墙板的低层装配式轻钢混凝土框架结构抗震性能,设计了2榀缩尺模型,包括1榀框架试件和1榀带有硅酸钙复合墙板的试件。通过低周往复荷载试验,得到了低层装配式轻钢混凝土框架的滞回曲线、骨架曲线、承载力和变形、强度退化、刚度退化和耗能能力。结果表明:硅酸钙复合墙板对低层装配式轻钢混凝土框架结构的性能有着显著影响,承载力提高了37%,初始刚度提高了31%,累计总耗能提高了32.27%;研究表明带有轻质硅酸钙板的复合墙板的轻钢框架具有较好的抗震性能。In order to study the seismic performance of a low-rise prefabricated light steel concrete frame structure with calcium silicate composite wallboard, two trusses of scale models were designed, including one truss specimen and one specimen with calcium silicate composite wallboard.The hysteretic curves, skeleton curves, bearing capacity and deformation, strength degradation, stiffness degradation and energy dissipation capacity of low-rise prefabricated light steel concrete frames were obtained by low cyclic load tests.The results show that the lightweight composite wall panel has a significant influence on the performance of fabricated lightweight steel concrete frame structure,the bearing capacity is increased by 37%, the initial stiffness by 31%,and the total energy consumption by 32. 27%. The light steel frame with composite wall panel with light calcium silicate plate has better seismic performance.
