摘要

摘要: 为研究有木隔板的木-混凝土组合梁斜交螺钉连接件的抗剪承载力，分析了有木隔板的木-混凝土组合梁斜交螺钉连接件的受力机理，分别建立受压剪作用螺钉连接件单铰弯曲和双铰弯曲的受力模型，受拉剪作用螺钉木材受压破坏、单铰弯曲和双铰弯曲的受力模型，以及斜交螺钉连接件的受力模型，提出了有木隔板的木-混凝土组合梁斜交螺钉连接件抗剪承载力的计算方法，并与试验结果进行对比。结果表明，提出的算式能够较好地预测有木隔板的木-混凝土组合梁斜交螺钉连接件的抗剪承载力。

Abstract: In order to investigate the shear bearing capacity of inclined cross screws in timber-concrete composite beams with timber board interlayer, mechanical mechanism of inclined cross screws was studied. Mechanical models for single plastic hinge and two plastic hinges in the shear-compression loaded screw were established. Mechanical models of lateral crushing of timber, single plastic hinge and two plastic hinges in the shear-tension loaded screw were established. The analytical model for predicting shear bearing capacity of inclined cross screw in timber-concrete composite beams with interlayer was proposed, and the calculated results were compared with the experimental results. The results showed that the shear bearing capacity of inclined cross screws could be predicted well by using the calculation method.
