Influence of some factors on the aerostatic and aerodynamic analysis of long-span suspension bridges;

Self-vibration characters of long-span suspension bridge and analysis of parameters;

Influence of some factors on the aerodynamic stability of long-span suspension bridges;

A Large number of technological challenges are presented in the design and construction of crossing sea and linking islands bridges,in which the aerodynamic stability of extra long span suspension bridges is a dominant concern.

Flutter stability is one of major factors governing the design of long span suspension bridges.

in long span suspension bridge are researched and discussed emphatically.

Research on increasing the air-operated steps of large span suspension bridge flutter critical wind velocity;

An introduction is given to major issues in design of anchor foundation for large span suspension bridge, and a analysis is given of several commonly-adopted foundation programs.

Spatial seismic response analysis of long-span suspension bridge across Sidu River;

Based on the FE model,model analysis is carried out and the effects of soil-pile-structure interaction on dynamic behavior of the long-span suspension bridge are specially studied.

In this paper,by taking the Sidu River Bridge as the example,a spatial dynamic model of long-span suspension bridges with steel truss stiffening girder is established,and the nonlinear motion equations in the multi-support excitation condition are deduced based on Leger s large-mass method(LMM) and the pseudo static displacement conception.
