In view of the characteristics of the integration of rail transit elevated structure and seamless route, this paper analyses the Metro Design Technical Standards (2003 edition) and proposes the principles of value selection for elevated structure in the new edition of code for metro design.

Fragility curves of viaduct structure were developed by capacity spectrum method and nonlinear dynamic analysis method respectively.

In this thesis, the sub-structure technique is adopted to perform nonlinear planar seismic response analysis considering soil-structure interaction for high-rise frame structures with box foundation or raft foundation resting on natural foundation soils.

As shows by example of calculation, it is a handy method with small error of calculation, It can be met with the demand of accuracy in calculation of engineering design, It is suitable for use in high-rise frame structure of reinforced concrete and also steel frame.
