%X Only the action of horizontal earthquake was considered generally when structure with MRD was analyzed. The correlation of movements in horizontal and vertical directions was not well studied. This paper considers the structure with MRD under bidirectional coupling earthquake. The dynamic analysis model is set up, kinetic differential equations are obtained, and dynamic time history analysis is made. Taking an 8-story structure with MRD for example, the results show that the seismic responses of the structure with MRD increase in some extent under the action of earthquake in vertical direction. Therefore, it is highly recommended that the influence of vertical earthquake action on such structures should be taken into account in high-intensity earthquake regions. The optimal model for structures with MRD is set up. The various earthquake responses of structures with MRD under various loading conditions can be better controlled after the optimization with IHGA.
