Anchorage performance of steel plate in reinforced concrete is the key to ensure working reliability of structural steel member splice(SSMS) to precast splice girder.

In light of the property of the steel-aluminum structural transition joints,several problems in the welding of steel-aluminum structure transition joint in the high-speed ship are analyzed from the view of mechanical behaviour,welding parameters and anti-corrosion capacity.

Shaking table tests on subway station joint structure and 3D numerical simulation of seismic response;

The quality of corrosion protection will directly affect the completeness and the service life of the wharf steel structure.

The effects of material, geometric shape, loading, stress gradient, residual stress on fatigue strength for welded steel structures are considered respectively.
