Seismic Analysis of Elevated Steel-concrete Composite Single Pillar Station Based on Models with Different Foundation Simulation
摘要
Abstract
The elevated station is a combination structure of station and bridge, and it is a building and also a part of the rail transit structure. For elevated single pillar station with long cantilever, its seismic resistance redundancy is low and it is important to make seismic analysis. Steel-concrete composite single pillar station is a new kind of structure system, which has the advantages of small dimension of the members, light weight of the structure and strong deformation resistance. It is worth researching the performance of the steel-concrete composite single pillar station under earthquake. There are different requirements for foundation simulation according to code for structure design of building and code for design of urban rail transit structure. Therefore, it is necessary to discuss the seismic analysis results based on different foundation simulation methods. Different analysis models are built based on engineering projects. The differences of calculation results are compared and analyzed, and some suggestions for design are proposed. Firstly, due to the torsion effect of the single pillar structure under earthquake action, special attention should be paid to the design of side components. Secondly, based on the particularities of the single pillar structure, the design should consider the interaction of pile and soil, and envelope design should be carried out to obtain different stiffness values of soil spring. Thirdly, the main components of the single pillar structure should be designed for seismic performance, and the objective performance of the single pillar pier is suggested to be elasticity of the seismic oblique section and non-yield of the normal section.关键词
