| 摘 要： | 在型钢混凝土粘结滑移的实验研究基础上,对均布荷载形式下型钢混凝土粘结滑移的分布规律进行了分析.由弹性力学理论,推导了型钢混凝土简支梁在均布荷载作用下滑移位移的函数关系式,并进行了数值计算与分析.计算表明,构件中型钢与混凝土界面的相对滑移的基本特征,与相关试验结论相一致.研究结果可以用来描述型钢混凝土界面的相对滑移规律,同时为研究型钢混凝土构件粘结滑移本构关系奠定理论基础.

| Abstract: | Based on the experimental researches of bond-slip behaviors of steel reinforced concrete,the distribution law of interface slip in SRC simple beams are investigated in the paper.By elastic methods the functional formulae of bond stress and location in SRC beams under the action of uniformly distributed loads are derived,and the corresponding data is calculated and analyzed.The result shows that the characteristics of bond-slip on steel and concrete interface are coincided with the test results.The law of in... |
