Abstract:The  Linyi North Station  Building of Lunan High-speed Railway is a “bridge-build” building with unique architectural form and novel structural form. The frame structure of box-shaped steel tube laminated column-concrete beam was adopted below the rail bearing layer, the frame structure of box-shaped steel tube laminated column-steel concrete beam was adopted in the waiting layer, and the frame structure of box-shaped steel tube concrete column-steel beam was adopted in the commercial interlayer. The roof was a spatial steel truss structure. The force analysis of the overall structure of the space was carried out, the continuous collapse resistance of the large cantilever truss of the main entrance was analyzed, and the finite element analysis was carried out on the cast steel support of the large-span arch truss of the belly and the large cantilever truss of the main entrance. And the full scale test of the large-diameter welding ball used in the large cantilever truss of the main entrance was carried out. Through the design and analysis, all the indexes meet the requirements of relevant specifications.

Keywords:Linyi North Station;arch truss;cast steel joint;large cantilever truss; welding ball
