Study on the Deformation Behavior in-Plane of a New Energy-Saving Wall

Abstract:

This paper selects a new building material—foam concrete which can be used by the outer wall system as a self-insulation material, and designs two sets of specimens which are carried out the experimental study under low-cycle reversed loading. The paper analyzes the failure mode of the walls, hysteretic curves, skeleton curves, ductility and energy-dissipation capacity. Experimental phenomena and results show: by reasonable construction measures, the new latticed energy-saving wall compared with the normal filling wall possesses better seismic capacity and shear capacity, meanwhile the ductility and energy dissipation capacity of the wall is good to meet the engineering requirements. On this basis, the force mechanism of the specimen is discussed, calculation formula of shearing capacity is put forward, and the calculation results meet well with the experimental results.
