摘要
本文结合国家某重点建设项目工程对钢一混凝土组合梁混凝土翼缘板的纵向抗剪进行了试验研究。根据8根两点对称集中加载试验架在静载作用下的试验结果，分析了组合梁纵向开裂的原因及主要影响因素，建立了组合梁纵向抗剪计算模型和计算公式，对于组合梁纵向抗剪计算和横向钢筋设计具有实用参考价值。
Based on the background of a state key construction proect, experiments have been conducted on the longitudinal splitting strength of concrete flanges in composite steel-concrete beams. Interms of the test results of eight beam specimens under two symmetrical concentrated loads, thecause of splitting and the factors affecting the splitting strength are discussed and analyzed in detail. Models have been established with formulae derived for predicting the splitting strength of.concrete flanges in composite beams. They can be used for the design of transverse reinforcementin such composite steel-concrete beams.
