Wind stability of long-span suspension bridges using carbon fiber reinforced polymer cables;

Analysis of the nonlinear aerostatic stability of a long-span suspension bridge under yawed wind

To gain understanding of the applicability of carbon fiber reinforced polymer(CFRP) cable in long-span suspension bridges,a 1490 m suspension bridge using CFRP cables is established,in which the cable s section is determined by the equivalent axial stiffness,the dynamic behavior,the aerostatic and aerodynamic stability of the bridge are analyzed by 3D non-linear computation theory.

Research on Completion States and Dynamic Characteristics of Large-span Suspension Bridges;

This paper used finite analysis software to study the form-finding of large-span suspension bridge and stressed characteristics before,in and after construction,gained the displacement of the midspan nodes in every stage.

Runyang Suspension Bridge(RSB) with a main span of 1 490 m was taken as an example,and the multi-scale finite element(FE) modeling method on super-long-span suspension bridges oriented to structural health monitoring and safety assessment was proposed.

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.
