摘要
为研究原梁纵向配筋率和混凝土强度等原梁参数对其高性能复合砂浆钢筋网(HPF)加固梁受弯受弯承载力和变形能力影响,设计了7根HPF加固梁足尺受弯试验.试验结果表明高性能复合砂浆钢筋网加固RC足尺梁是一种有效的加固方法,能够显著地提高RC足尺梁的抗弯承载力、截面刚度以及抗裂性能;原梁参数对其加固梁的受弯性能改善效应影响显著.
Experimental study was conducted on the flexural bearing capacity and deformability of high-performance ferrocement strengthened beams, which were subjected to tension reinforcement ratio and concrete strength of original RC beams. The experimental results indicate that the reinforcement with high-performance ferrocement is an efficient method to reinforce RC beams, which can obviously increase their load-bearing capacity, rigidity of section and crack resistance behavior. Parameters of original beams affect the flexural behavior of the strengthened beams remarkably.
