In the paper the performance of the composite steel frame-reinforced concrete infill wall in which the wall is cast-in-place is generalized, and the construction method for the composite steel frame-precast reinforced concrete infill wall is proffered, and elastic finite element analysis is performed. The deformation and distribution of stress under mono-loading are achieved. And the behavior of the system when the infill wall is precast is analyzed and compared to previous conclusion, the results and some conclusions are achieved.
