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、施工简便且耐腐蚀性好等优点。在已有的混凝土双向板外贴板加固试验研究成果[1] 的基础上 ,进一步应用塑性铰线理论对承受均布荷载的混凝土矩形双向板用外贴薄板加固后的最终塑性铰线模式及其承载力进行了分析计算 ,在此基础上提出了适用于该类加固板的实用设计计算方法及设计表格 ,并编制了相应的通用程序
Reinforced with externally bonded FRP or steel sheet reinforcements are used to reinforce reinforced concrete slabs with significant reinforcement, ease of construction and good corrosion resistance. On the basis of the existing experimental results of two-way concrete slab-board reinforcement [1], the plastic hinge line theory is further applied to determine the final plastic hinge line mode of the reinforced concrete two-way slab strengthened with the externally affixed thin plates and Its carrying capacity is analyzed and calculated. Based on this, a practical design calculation method and design form suitable for this kind of reinforcement board is put forward, and corresponding general procedures
