Through low reversed cyclic horizontal loading tests of three composite walls, the influence of one sided cladding of strawboard, one sided cladding of strawboard with steel X strip bracing and steel plate strawboard double boards on the anti seismic behavior of composite walls were investigated. The results indicate that the steel X strip and one sided cladding of steel plate are used to increase the interaction between straw board and the steel frame, and the anti seismic behavior is better. The shear bearing capacity of the one sided cladding of strawboard composite wall with steel X strip bracing is similar to that of the steel plate strawboard double boards composite wall, which is about 2 times as much as the shear bearing capacity of the one sided cladding of strawboard composite wall. And the ductility coefficient and lateral stiffness of composite walls are significantly improved, but the energy dissipation performance of the composite wall with steel X strip bracing decreases slightly. The stiffness degradation rate of 3 composite walls is uniform, stable and streamlined. The one sided cladding of strawboard composite wall with steel X strip bracing is compared with the steel plate strawboard double boards composite wall, the fluctuation range of shear bearing capacity degradation coefficient is small, and the shear bearing capacity is more stable. In practical engineering, steel consumption of the steel X strip is less, and it will have practical value.
