【摘要】 波形钢腹板PC组合箱梁是一种新型的钢-砼组合结构,由于其良好的受力性能在日本和欧美得到了广泛应用,其优势在于它充分利用了钢和砼的材料特点.而抗剪连接键是能否为结构提供足够完整的组合作用的一个决定因素,本文介绍了波形钢腹板PC组合箱梁抗剪连接键的受力性能分析与设计计算方法,并介绍了国内首座波纹钢腹板公路桥———大堰河中桥的抗剪连接键的计算实例.更多还原

【Abstract】 The prestressed concrete composite box girder with corrugated steel webs is a new type of steel-concrete composite structure,which is have been extensive used in Japan and European countries lies in its super-performance on mechanics,because the superiority is making fully utilize of material characteristic of the steel and concrete.Shear connector is a decisive factor whether it can provide a sufficient integrated action to the composite structure or not.The paper introduces the analysis of mechanics capability and design methods of shear connector of the box girder with corrugated steel webs. Furthermore,example of shear connector design in first similar internal bridges——DA YAN HE bridge is offer.更多还原
