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.
