There is a relative lack of research on the seismic performance of lightweight steel and lightweight concrete composite wall panels.Therefore,in order to investigate the influence of different fillers on the seismic performance of lightweight steel skeleton cement fly ash foamed wall panels,three wall panels with different fillers were designed to carry out a low circumferential reciprocating horizontal loading test,to analyze and study the influence of different fillers on the seismic performance of the wall panels.The results showed that the damage modes of the wall panels with different filler ratios were more or less the same,and the wall panels have better integrity and seismic performance;the incorporation of polypropylene fibers and the increase of cement dosage in light steel skeleton cement fly ash foamed wall panels can effectively improve the seismic performance and lateral stiffness of the walls,enhance the bearing capacity and ductility of the walls,and also significantly increase the deformation capacity as well as the energy-consuming capacity of the walls.Compared with the control group,the wall paneled with 0.4%polypropylene fibers or increased cement dosage up to 50.0%both increased the shear bearing capacity by about 54.0%,the lateral stiffness by 26.0%and 15.0%,and the cumulative energy consumption by 172.0%and 86.0%,respectively.
