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.

A seismic response analysis of a reinforced concrete (RC) pier has been undertaken using seismic waves recorded at the Takatori station during the southern Hyogo perfecture earthquake in 1995 in Japan. Distinguishing characteristics of this analysis are as follows. First, the RC pier has been modeled using the finite element method with a solid mesh. The analysis model has been generated using tetrahedral elements with node connectivity, not only in the concrete but also in the reinforcement steel. Also, an analysis has been undertaken on fracture treatments in the concrete. Using PDS-FEM, a system of suitable fractures in the concrete resulting from the seismic event can be simulated. Ultimately, a finite element model is established with a fine tetrahedron mesh with about 20 million elements. We calculate a seismic response analysis using the K computer at the RIKEN Advanced Institute for Computational Science, and compare that result with a seismic experiment in E-Defense to confirm the computational approach.

The Finite Element Analysis

Abstract To study the influence of soil-well bore-shaft tower interaction on the seismic response of the shaft tower. A numerical analysis model of rigid foundation (without considering the interaction of soil-well bore-shaft tower ) and II site considering soil-well bore-shaft tower interaction is established by the finite element analysis method. The mode period, tower layer displacement and inter-story displacement of shaft tower are analyzed. The results show that, compared with rigid foundation, considering the interaction of soil-well bore-shaft tower, the mode period of the system is prolonged, the tower layer displacement and inter-story displacement of the shaft tower is enlarged. In the engineering design of shaft tower, the influence of the soil-well bore-shaft tower interaction on the seismic response of the shaft tower cannot be ignored.
