摘要
钢筋和GFRP筋合理混杂布置,可较大程度地提高混凝土结构的耐久性。通过对8根梁的抗弯试验研究,证实GFRP筋、钢筋和混凝土可以很好地共同工作。依据实验结果和理论分析,提出了混杂配筋混凝土梁抗弯承载力计算方法。
Proper hybrid distribution of steel bars and GFRP bars can improve the durability life of concrete structures in significantly, and thus it is a good structure system. Flexural capacity of eight concrete beams were tested , and the experimental results showed that GFRP bars could work well with steel bars and concrete. The property of ductile fracture of the beam cross section is recommended. And the conversion ratio reinforcement of the allowable maximum elastic module and the conversion ratio reinforcement of the allowable minimum strength are also putted forward. Based on the＇test results and theoretical analysis, the calculation method of flexural capacity of the hybrid reinforced concrete beams is presented.
