摘要
带裂纹的钢筋混凝土梁用钢板直接粘于混凝土梁表面进行加固,形成新的组合断面梁。这种梁的挠度及位移用理论计算不理想。本文采用物理模拟方法,用激光散斑干涉原理,测试了梁的挠度。
The R. C. beam with steel-bonded reinforcement is a complex member. It is difficult to de-termine the deflection of the beam with crack by theoretical calculation. In this paper, the deflections of the R. C. beam with steel-bonded reinforcement are obtained by using the in-terference principle of laser speckle.
