摘要
采用Super91程序对双材料粘结试件和整体试件的劈拉受力进行数值模拟.从应力分析角度研究在劈拉荷载作用下,新老混凝土粘结的应力分布规律。研究结果表明新老混凝土粘结劈拉强度计算公式可近似采用整体混凝土劈拉强度计算公式。
The numerical simulation is implemented by means of Super91 program dealing with bi-material adhesive specimen and whole specimen. The stress distribution law of adherence of young on old concrete under splitting-tension load is studied as viewed from stress analysis. The results turn out that the splitting-tension strength formulation of whole specimen is a good approximation to the adhesive specimen.
