Abstract: Shuttle-shape steel latticed column is widely applied in large-span steel structure due to its light self-weight and beautiful appearance. The design procedure of the shuttle-shape steel column which is used in the project of Jinan Western Bus Terminal was introduced. The buckling load of the shuttle-shape steel column considering the initial imperfection was obtained by the analysis of SAP2000. The ultimate stability bearing capacity of the column was calculated with the simplified formula. The cast steel joint was used as the connection of beams due to its convenience in production and installation.The fixed hinged support was used to satisfy the rotation requirements of the column.The practice result demonstrates that the shuttle-shape steel latticed column is safe and reliable, and the measures adopted can be used in other similar projects.

Keywords: shuttle-shape steel latticed column; buckling load; ultimate stability bearing capacity
