沈阳北站无站台柱雨棚由17榀钢桁架组成，桁架间通过钢檩条连接，上铺彩钢板。由于雨棚功能不足，因此进行了屋面增设铺板改造。根据模拟计算，从增加覆盖面积、增加斜拉索、全覆盖等几个方面对方案进行了比选研究，确保改造工程的安全性、经济性、可实施性。改造方案最终确定为增加斜拉索方案。对沈阳北站需改造的无站台柱雨棚，通过调整结构内力重分布来满足改造后结构的受力要求，回避了对既有雨棚结构杆件加固补强问题，确保了雨棚改造的可实施性，为今后类似铁路无站台柱雨棚改造工程提供参考。

The canopy without station column in Shenyang North Railway Station consisted of 17 steel trusses which 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 out. According to the simulation calculation,the comparison study among the seismic assessment,strengthening and reinforcement of web patch were carried out to guarantee the secu-rity , economy and enablement of the engineering. Reconstruction program was finally confirmed to increase stayed-cable. The canopy without station column in Shenyang North Railway was adjusted to the structure of the in-ternal force distribution so as to satisfy the requirement stress of the reconstructed structure,avoiding the reinforce-ment of the existing canopy structure bar and guaranteeing the engineering enablement of the canopy. A reference of the similar reconstruction project of railway canopy without station column was provided in the future.
