Improved Model

Through analysis and comparison of some nonlinear seismic response analysis models for structures of bridges with pile foundation, considering the effect of deformation performance of pile foundation whose nonlinear properties of foundation and the component are taken into account, this paper presents an improved model relatively. In order to verify the rationality of the improved model proposed in this paper, the calculation and analyses of the test model of a single pier with pile foundation through pushover are done, and the results are compared with the experiment results.The pile foundation does not damaged under seismic load; The improved model can reflect material nonlinearity of the actual soil contact between soil and pile, and the dispersed spring model can be better to simulate the postural nonlinear of pile-soil contact and separation; at the same time, we need to consider vertical friction spring in the pile side.

Calculation Results

As an effective way of passive damping, isolation technology has been widely used in all types of building structures. Currently, for its theoretical analysis, it usually follows the rigid foundation assumption and ignores soil-structure interaction, which results in calculation results distortion in conducting seismic response analysis. In this paper, three-dimensional finite element method is used to establish finite element analysis model of large chassis single-tower base isolation structure which considers and do not consider soil-structure interaction. The calculation results show that: after considering soil-structure interaction, the dynamic characteristics of the isolation structure, and seismic response are subject to varying degrees of impact.
