Abstract：
In-depth design of steel structure is significant to steel structure construction. This paper described material replacement, welding form of combined member, installation of column base and design of splice point. Relevant parameters were calculated, such as welding bearing capacity and wind load, etc. It was proved that all values satisfied the requirements after in-depth design.
