Abstract:The roof  of Jinan East Railway Station  is a fully covered complex hyperboloid linked-to-ground arch structural system, with a roof span of 122～156m and a length of 406-6m. In order to satisfy the architectural conception, parabola was determined as hyperbolic line type by line type comparison and selection, and hyperbolic parabola arch was defined by mathematical analytic equation. Considering the technical index and economy, four kinds of roof supporting systems were compared, and the scheme of adding columns at the elevation of 10-2m was finally determined. The analysis shows that the stability of the roof structure meets the requirements of the code, the structural rigidity is large, and the steel consumption index is economic. In this scheme, the maximum span of the roof is  156m, which refreshes the structural span of domestic high-speed railway passenger station, and provides a reference for the design of similar high-speed railway passenger station roof structure in the future.

Keywords:Jinan East Railway Station; complex hyperboloid; structural span; mathematical analysis; scheme comparison and selection
