摘　　要：本文首先介绍了腹板嵌入式组合梁的概念,分析了这种组合梁中连接件的性能。其次,通过8个抗冲切试件的试验研究,研究了腹板嵌入式组合梁中连接件的抗冲切性能,分析了冲切承载力的不同影响因素。最后,综合各影响因素推导出腹板嵌入式组合梁中连接件的抗冲切承载力计算公式。通过公式计算值与试验结果的对比,验证了公式的适用性。This paper introduced the conception of the embedded composite beam with notched web firstly, and analyzed the performance of the shear connector in this kind of composite beam. Then, through the experiment of the 8 punching specimens, the performance to resist punching of the shear connector in embedded composite beams was studied, and different influence factors to resist punching were analyzed. In the end, the formula to calculate the bearing capacity to resist punching of the shear connector in embedded composite beams is concluded concerning important influence factors. By comparing the experimental and the theoretic results, the formulas proposed in this paper are verified.
