中文摘要：

江苏泰州市火车站大跨拱形钢雨棚为无站台柱雨棚,大跨度雨棚主体结构采用钢管混凝土柱与空间倒三角钢管桁架,为风敏感体系。通过风洞试验和风振分析确定工程设计参数,采用三维有限元模型进行内力分析,包括温度作用和水平推力对超长大跨拱形结构的影响,并对结构的整体稳定性进行分析,同时采用合理的支撑体系保证结构的整体刚度。

英文摘要：

For a long-span and arched steel canopy without column on platform in Taizhou railway station , the steel pipe column filled with concrete and steel pipe truss with inverse triangle section were used for its main structural system.As a sensitive system to wind load , engineering design parameters were determined through wind tunnel test and vibration analysis; the internal forces were analyzed by three-dimensional finite element model , including temperature action and the influence of horizontal propulsive force on the long-span arched steel canopy; and the entire stability was studied;through rational support system , the structural stiffness was ensured also .
