| 摘 要： | 结合波形钢腹板PC组合箱梁桥抗弯特性，对该类桥的抗弯承载能力计算方法进行了探讨。分析了波形钢腹板组合箱梁有效分布宽度、偏载效应的已有研究成果，参考国外对该类桥中体外预应力筋的有效高度和极限应力取值，根据弯曲理论推导出波形钢腹板PC组合箱梁桥抗弯承载能力计算公式。模型梁算例表明，该计算方法简单可行。

| Abstract: | Combined with the flexural behavior of the prestressed concrete box-girder bridge with corrugated steel webs, the computation method of ultimate moment capacity was studied, some design properties were analyzed, such as the effective width of box-girder with corrugated steel webs, eccentric load effect and the ultimate stress increment and effective depth of externally prestressing tendon. The formula of ultimate moment capacity of the prestressed concrete box-girder bridge with corrugated steel webs was deduced with elementary beam flexure theory. An example shows that this method is simple and feasible. |
