Abstract

Mega-sub structure is a new type of structure system of shock absorption. In order to give full play to its shock isolation performance, in this paper we utilize the finite element method software ANSYS to establish isolation bearing units evenly arranged in the bottom of the substructure column, which forms a new Mega-sub shock isolation structure system. Meanwhile, for the sake of analyzing the isolation effect of the Mega-sub structure, a three-dimensional finite element simplification model of Mega-sub structure is established as well; and then Mega-sub structure is compared with the general mega-frame structure. First, the self-vibration period and frequency of the two structures are discussed by the modal analysis. Second, with the time-history analysis of the same seismic wave carried out, we analyze the corresponding values including displacement and acceleration of the two structures. It turns out that Mega-sub structure with isolation bearing possesses a good vibration isolation effect.
