【摘要】 借助有限元分析程序,对曲线和直线连续型钢桁架桥在设计荷载作用下的结构性能进行对比,并通过荷载试验对曲线型钢桁架桥受力性能进行研究.从分析结果来看,在承受相同荷载情况下,直线型钢桁架桥弯矩效应和挠曲变形皆小于曲线型,直线型桁架桥比曲线型钢桁架桥拥有更好的结构性能,安全储备比曲线型钢桁架桥要高,受力性能更突出.更多还原

【Abstract】 The structural performance of curve continuous steel truss bridge is compared with linear bridge under design load with finite element program.The behavior of curve continuous steel truss bridge is studied by the load test.From the analysis results,the bending effect and deflection of linear steel truss bridges are less than curve bridges,linear continuous steel truss bridges own better structural performance than the curve bridges,safety stock is more than the curve steel truss bridges and the mechanical performance is more outstanding.更多还原
