外贴纤维增强复合材料 (FRP)或钢薄板的补强技术用于加固钢筋混凝土板 ,具有加固效果显著、施工简便且耐腐蚀等。应用塑性铰线理论对承受集中荷载的钢筋混凝土外贴薄板加固双向板的承载力进行计算 ,在此基础上提出了适用于该类加固板的实用设计表格。
The reinforcement technology of FRP or steel sheet is used to reinforce the reinforced concrete slab. The reinforcement effect is remarkable, the construction is simple and corrosion-resistant. The plastic hinge line theory is used to calculate the bearing capacity of reinforced two-way slabs reinforced by externally loaded concrete slabs subjected to concentrated loads. On this basis, a practical design form suitable for such reinforcing slabs is proposed.
