Combined with the structural design of elevated train station along Tianjin-Binhai mass transit project, the design problems about elevated train station are introduced, such as structure type, load value and load combination, structural analysis, member design and foundation design etc. The difference between the codes for the railway bridge design and for the ordinary building structural design in load combination, member design etc is compared. The effect of temperature change and foundation differential settlement on the structural internal force is analyzed. It gives some correlative design suggestions.
Keywords: station-bridge structure; loads; floor slab stiffness; temperature; differential settlement; pile foundation
