Study on the seismic performance of five self-insulating inner-framed bearing walls (SIBWs) by low cycle cyclic loading test. The results show that the opening has a significant influence on the hysteretic curve, skeleton curve, stiffness and energy-dissipation capacity of the SIBWs. The failure process of the test wall is characterized by the interaction, transition and weak framework stages, all of which show ductile failure. In theory, based on the equivalent elastic plate model, the calculation method of the wall cracking load is established. Based on the idea of the shear resistance mechanism, the diagonal compression bar model of the rigid frame is proposed, the method of determining the width of the diagonal compression bar is clarified by using the equivalent stiffness method, and the calculation method of the ultimate load of the wall is established. A comparison with the measured values shows that the calculation method is accurate.
