摘要
钢筋和GFRP筋合理混杂配置,可较大程度地提高混凝土结构的耐久寿命,是一种优良的配筋形式。通过8根混杂配筋混凝土梁的抗弯试验,分析了混杂配筋混凝土梁裂缝和荷载-挠度的特点,并根据试验结果和理论分析,推荐了混杂配筋混凝土梁裂缝宽度和挠度的计算方法。
Proper hybrid distribution of steel bars and GFRP bars can improve the durability of concrete structures in significantly, thus it is an excellent reinforcement format. Flexural capacities of eight hybrid reinforced concrete beams axe tested. Based on the test results, the characteristics of crack and load-deflection relation of hybrid reinforced concrete beam axe studied and a method is suggested for calculating the crack width and deflection of the hybrid reinforced concrete beam.
