PC、PPC梁分段施工接缝混凝土抗拉强度降低系数的试验研究

Experimental Investigation of Tensile Strength Reduction Factors of Concrete at Cast-in-Place Joints on PC,PPC Segmental Girders

根据 17片具有分段灌注施工接缝的 PPC模型梁的试验结果 ,提出了分段施工湿接缝混凝土抗拉强度降低系数的建议值 ,可供 PC。

Based on the results of 17 tested PPC model beams with cast\|in\|place joints,the tensile strength reduction factors of concrete at the joints are proposed,which may be used in the design of PC,PPC segmental girders.
