Abstract: Wall-beam-column combined structure is a new structure system with excellences of light weight,environment protection,energy saving and good construction performance.It can be widely applied to low-middle story buildings.Its structural behavior is a key to decide whether it can satisfy building safety and working function.For examining it,a two-story structure with full size was loaded horizontally under constant vertical load.The corresponding failure mode,weak positions and stiffness degrading property are discussed.From these test results,some important conclusions will be provided to further optimize and rationally design this structure.
