摘要
Abstract
In order to study the seismic behavior of lager special-shaped composite structure composed of different materials,analysis model is established by the finite element analysis and design software MIDAS/Gen.The bottom of the structure is regular concrete frame and the upper is closed cylindrical steer structure.In calculating the group damping ratio of the whole structure,influence of different material damping ratio is considered.Earthquake response spectrum analysis is carded out on the whole structure,and structural displacement and stress distribution is calculated under the action of horizontal seismic.The analysis result shows that different types of structures will make the composite structure producing large deformation,effective measures should be taken;effect of group damping should be considered in composite structures of different materials.关键词
