Based on the analysis of the geometrical models in a simple flexible suspension bridge,the skyline tension and it s errors in calculation were analyzed.

Simple flexible suspension bridges are widely applied to the bridge engineering of cities and countries in Fujian Province.

Flexible suspension bridges fully exert the characteristic that the high-strength steelwires can bear greatly high tension, so we can build larger bridge without higher tower.

It is important to analyze the dynamic characteristic of flexible suspension bridges because of its lower rigidity.

It also analyses deformation control ways for flexible suspension bridges,and finally proposes two methods to control deformation based on the thinking of increasing "the structure gravity rigidity".

Finite element analysis on structure of suspension bridge with APDL;

Scheme optimization for a flexible suspension bridge s maintenance;

The effect of vector-span ratio of main cable on economic and technical index of long span suspension bridges;

Stability parameter pnalysis of wind resistance and wind tunnel test for long-span self-anchored suspension bridges;

Flutter stability analysis of suspension bridges by precise time-integration method;

Analytical solution of installing curve of suspended bridge s main cable;

In combination with the fuzzy theory with the neural network,a fuzzy-neural network for safety assessment of the long-span suspended bridges is set up.

According to the actuality of fast development of road cosntruction industry,it discusses the developing trends of road bridge from board bridge,pile bridge,steel reinforcing concrete arch bridge,slanting bridge and suspended bridge,so as to promote the development of road bridge in China,and can be reference for bridge designers in China.

Research of detection and maintenance on cable suspension bridge;

Among them, cable suspension bridge is widely used for its widest spanning structure.
