外贴碳纤维(CFRP)布和钢板补强技术已广泛用于加固钢筋混凝土结构，迄今为止，对外贴碳纤维或钢板的加固梁的研究已做了许多，但对用该技术加固钢筋混凝土板的研究还很少。为此，本文着重对受集中荷载的外贴碳纤维或钢板条带的钢筋混凝土加固双向板的受力性能进行了试验研究。并采用塑性铰线理论对该类板的塑性铰线模式和加固板的承载力进行了分析和计算。 Carbon fiber reinforced plastics (CFRP) and steel reinforcement technology have been widely used to reinforce reinforced concrete structures. So far, there have been many studies on reinforcing beams externally bonded to carbon fiber or steel plates. However, studies on strengthening reinforced concrete slabs using this technique Very few. Therefore, this paper focuses on the experimental study on the behavior of two-way slab strengthened by reinforced concrete with externally loaded carbon fiber or steel strip. The plastic hinge line model and the bearing capacity of the plate are analyzed and calculated by the plastic hinge theory.
