【Abstract】 In this paper, according to the seismic action as a random process and variation in space, the stability and unstability of trip understructure was researched using the theory of beam on elastic foundation. Furthermore, after analyzing a simple example, it obtained that dynamic calculation was simplified to quasi static in the seismic design.更多还原
