根据 1 6片粘贴复合材料玻璃钢板加固的混凝土梁的试验结果 ,提出了补强加固后混凝土梁截面变形协调的准平面假定 ,在此基础上 ,对补强梁开裂前的弹性内力、开裂内力及开裂后的截面内力进行非线性分析计算 ,为进一步对补强梁的刚度计算打下了基础 . Based on the experimental results of 16 reinforced concrete beams bonded with composite glass plates, a quasi-planar assumption for the coordination of the deformation of reinforced concrete beams was proposed. On this basis, the internal forces and internal forces of cracking of the reinforced beams before cracking were established. The analysis of the internal force of the cracked section is performed by nonlinear analysis, which lays a foundation for further calculation of the stiffness of the stiffened beam.
