And SPA-H steel is a perfect shipboard container's material for its excellent anti-atmospheric and anti-seawater corrosion attribute.

The Single Input and Single Output(SISO)modal experiment and numerical simulation was used to study the dynamic behavior of a CFST column-H steel beam frame structure model.

The method and the operation of the fully and automatically improved fusion electrode welders were presented, the method could ensure the welding quality of H steel, and increase the welding velocity.
