The method and computing program of the elastoplastic time history analysis for the frame structure with braces are developed by means of the basic principle of the structural elastoplastic time history analysis, referring to the characteristic of the reinforced concrete frame structure with braces. The program is used to calculate the response of three types of frame structures with braces used in the construction engineering under the action of the seismic wave, and the response property of this kind of structure is analyzed. The calculating results illustrate that the shape of braces has a remarkable effect on the dynamic property of this kind of structure. The response properties of the frame structures with different shapes of braces under the action of the seismic wave differ remarkably.
