The results show that main cable stiffness not only has greater effect on the structure shape of long-span suspension bridge, it also has obvious impact on structure free vibration frequency, in addition, the torsion displacement of stiffening girder can be reduced effectively by adding central buckle, it improves structure bending and torsion stiffness significantly, central buckle also can improve free vibration frequency of structure and enhance structure dynamic stability, It shows that the influencing factors of structure static characteristics are restricted by rigidity of main cable, free vibration characteristics are affected by main cable and central buckle, they are not very sensitive to the variations of the parameters of suspender cable, stiffening girder and main tower.
In recent decades, with the development of economic, the standards of mechanical safety of bridge structure are raised.
Generally suspension bridge is flexible structure, it is composed of main cable, sling, stiffening girder, cable tower and anchorage, only the former four terms are taken into consideration while building the structure finite element (FE) model, the structure parameters, which corresponding to the four terms, will affect the structure mechanical characteristics.

The surface roughness is one of the most important factor affecting coating performance of the WPCs.
The final properties of WPC depend on the properties of the original (raw – untreated) components: character of reinforcement, i.e. wood flour (or fibres) and matrix.
They are affected to a large extent also by the used additives.
The products made of WPC are most often used in outdoor applications as in comparison with the natural wood they require almost no care, so they surpass the wood from the viewpoint of all physical and mechanical properties.
Therefore, the surface properties of the WPC samples were determined by employing a fine stylus profilometer Mitutoyo SJ-401 surface roughness tester.
