粘钢加固对钢筋混凝土梁内应力的影响

Influence of Steel-bonded Reinforcement on the Internal Stress of a Reinforced Concrete Beam

本文采用光弹性试验方法对钢筋混凝土简支梁粘钢加固前、后的受力性能进行了试验研究,从而获得了简支梁在出现裂缝前、后的应力分布状况,可供钢筋混凝土简支梁粘钢加固设计参考。

The stress behavior before and after steel-bonded reinforcement for the reinforced concrete simply supported beam is studied by adopting the photoelastic experiment method. The cir-cumstances of stress distribution before and after the cracks occurred on a simply supported beam are made out and can be aveilable for reference in steel-bonded reinforcement for the reinforced concrete simply supported beam.
