Abstract

Shenyang North Ｒailway Station canopy without station column was consisted of 17 steel trusses ， connected by steel purlines and the upside was paved with color plate． Due to insufficient function，the study of roof additional ceiling reconstruction project was carried． According to the simulation calculation，it was compared the schemes from increase in area，adding more cables and all coverage etc，which could guarantee the security，the economy and the operability of the project． The scheme of increasing stayed cables was confirmed，with which the redistribution of structural inner forces was adjusted to satisfy the force requirement of the reconstructed structure，and avoid the reinforcement of the existing canopy structure members and guarantee the project operability of the canopy．
- canopy without station column,
- prestress,
- cable-stayed truss,
- wind tunnel test
