| 摘 要： | 通过对6根RC足尺梁受弯试验，研究不同强度等级RC足尺梁采用高性能复合砂浆钢筋网加固后的受弯性能。主要分析原构件混凝土强度和加固砂浆强度匹配对加固梁受弯承载力、刚度及抗裂性能影响。依据平截面假定和试验结果，提出梁的受弯承载力、刚度计算公式。依据建立的公式计算受弯极限承载力和挠度值与试验值吻合较好，可为实际加固工程设计提供理论参考。

| Abstract: | Experimental research on flexural behavior of the different grade RC beams strengthened with ferrocement mortar through six RC beams is carried out. The matching of original component concrete to the composite mortar strength rank is studied and its influence on bending strength, the crack-resisting capacity and the bending stiffness of RC beams is analyzed. Based on plane cross-section assumption and the experimental results, the formulas of the theoretical ultimate strength capacity and stiffness are brought forward. The calculated results fit well with the experimental results, to provide a theoretical reference for actual engineering designs. |
