将一定几何尺寸的玻璃钢板粘贴在混凝土梁的受拉区，能有效地提高混凝土梁的抗弯承载能力和混凝土梁的横向刚度。通过解析的方法，分别考虑组合梁在3种不同受力状态下，对玻璃钢板中拉力进行解析，得到了组合梁在不同载荷作用下的挠度表达式。
The GFRP plate was epoxy-bonded to the tension flanges of RC beam, which can effectively improve the bending strength and the lateral stiffness of the RC beam. In this paper, the pulling force of GFRP plate and the deflection of the plated beam have been analyzed when the plated beam bears three different loads. The results can guide experiment and study in the future.
