The composite shear wall system with permanent thermal-insulation wall form of glazed hollow bead is a new kind of energy-saving building. the experimental study on the seismic performance of composite shear wall structure was proposed. Through the tests of the walls with different shear-span ratio and axial compression ratio under vertical force and low cyclic horizontal load, the seismic behaviors of slitted shear walls under low cyclic load tests were studied. Through the expemental study, the calculation methods for load-bearing capacity of walls with different shear-span ratio were obtained. And then the laws for the energy dissipation and ductility feature were revealed. Besides, the comparison analysis were made on the seismic behaviors between composite shear walls and common shear walls.The study could provide a foundation for the designing evaluating on the performance for the new structure.
