钢板组合梁桥国内外设计探讨

Discussion on Design of Steel Plate Composite Beam Bridge at Home and Abroad

为推广钢板组合梁桥在国内的广泛应用,对钢板组合梁桥国内外的设计情况及发展趋势进行分析,对国内典型钢板组合梁桥的结构特点、设计要点、构造尺寸及用钢量进行对比,对钢板组:合辦桥的经济跨径进行总结。分析表明:钢板组合梁在35~100 m跨径中应用广泛,并且钢板组合梁桥正逐步从多主梁向双主梁的趋势过渡,双主梁桥型被认为是一种极具经济性的桥梁形式。

In order to promote the wide application of the steel plate composite beam bridge in China,the design situation and development trend of steel plate composite girder bridge at home and abroad are analysed.The structural characteristics,design essentials,structural dimensions and steel consumption of the typical steel plate composite girder bridges in China are compared,and the economic spans of steel plate composite girder bridge are summarized.The analysis result shows that steel plate composite girder is widely used in 35?100 m spans,and steel plate composite girder bridge is gradually from multi-girder to double-girder trend transition.Double-girder bridge is considered to be a very economical bridge form.
