【摘要】 外贴高性能碳纤维 (CFRP)布和薄钢板条的补强技术可有效地加固钢筋混凝土结构。基于对受集中荷载的外贴碳纤维布或钢条带的钢筋混凝土双向板的试验研究 ,并在Hillerborg高级条带法的基础上提出了计算外贴条带加固双向板承载力的塑性条带法 ,该法比Hillerborg高级条带法具有更高的计算精度 ,且仍偏于安全。更多还原

【Abstract】 The RC structures can be strengthened effectively using external high performance CFRP sheet or thin steel plate.The behavior of the strengthened two-way slabs bonded with strips made of CFRP or steel and subjected to a central patch load was investigated in this paper.A plastic strip method employed to predict the load bearing capacity of the two-way RC slabs strengthened with CFRP strips was first proposed in this paper on the basis of the Hillerborg′s advanced strip method.Comparison of the ultimate loads of the experimental plated slabs using these two methods reveals that the plastic strip method is of more precise and still on the safe side.更多还原
