钢筋交叉搭接桥面板湿接缝轴拉试验研究

预制拼装桥梁主梁横向接缝常采用钢筋交叉搭接的桥面板湿接缝形式,但是此连接方式的计算方法有待完善,正常使用性能尚无试验数据基础。通过轴拉试验揭示不同缝宽、钢筋形式、接缝材料组合下桥面板湿接缝的性能,为理论计算方法提供试验数据,为设计提供参考。

Study on Axial Tension Test of Wet Joint of Rebar Cross Lapped Deck Slab

The transverse joint of precast bridge girder usually adopts the wet joint form of deck slab with steel bar overlapping, but the calculation method of this connection mode needs to be improved, and there is no test data basis for normal service performance. The performance of wet joint of bridge deck under different joint width, reinforcement form and joint material combination is revealed through axial tension test, which provides test data for theoretical calculation method and reference for design.
