Experiment on Seismic Performance of Prefabricated Light Steel Composite Wall
Prefabricated light steel composite wall is a new type of wall integrating load-bearing,thermal insulation and enclosure.In order to study the seismic performance of prefabricated light steel composite wall,four full-scale specimens were designed for low cyclic reversed loading test with light steel keel form and infill material type as variable parameters.The horizontal bearing capacity,hysteretic characteristics and failure characteristics of all specimens were obtained,and the lateral stiffness,energy dissipation capacity and horizontal bearing capacity of the structure were analyzed.The results show that the light steel frame of the wall and the infill material work well together,and the final failure characteristic of the wall is the strength failure of the steel frame.Adjusting the horizontal keel from C-shaped steel to double-sided flat steel can improve its horizontal bearing capacity,but it will reduce the ductility and energy dissipation capacity of the wall.The horizontal bearing capacity,stiffness and energy dissipation capacity of the wall filled with polystyrene foam concrete are lower than those of the wall filled with foam concrete,but the ductility is improved.
