The Study Of The Equivalent Input Seismic Waves On The Box Foundation

A concept of "equivalent input" of considering SSI was put forward. The so-calledequivalent input method is the use of reasonable access to the top of the basic groundmotion. Considering the ground motion have been fully taken into account SSI. Thismethod can put the dynamic question of open system switch to closed system, so that bothcan make use of the traditional assumption that the rigidity of the foundation, but also takesinto account soil-structure interaction. In this paper, the calculation accuracy of theequivalent input was verified by frame with box foundation.specific work are as follows:1 First, consider the soil-structure interaction and analysis of the concept of thecurrent situation and development of a more comprehensive summary and to identify thefocus of this article research for the equivalent of ground motion input method.2 Use of post-secondary development of ANSYS finite element program for examplefor the earthquake response analysis, explore seismic equivalent of the input source oftheoretical thinking, And one instance of analysis to verify the feasibility of importequivalent.3 The equivalent for the importation of the relevant factors for its simulation analysis,are taken into account soil-structure interaction of these factors under the law and furtherexploring the feasibility of equivalent input.At last, the paper summarized the whole contents, and put forward the further contentsthat would to be researched.
