摘要
选取某单线铁路2×64 m连续钢桁梁桥为研究对象,应用Beam188单元建立有限元模型,分析了静风荷载作用下桥梁结构的受力性能,指出静风荷载对连续钢桁梁桥的两端桥门架有较大的影响。
Taken 2 × 64 m continuous steel-truss-bridge in one single track railway as research subject, utilizing Beam188 unit finite element model is built. The mechanical behaviors of this bridge under dead-wind load are analyzed. Author ponits out dead-wind load have greater influences on portal frames of continuous steel-truss-bridge.
