SHEAR BEHAVIOR OF RECYCLED CONCRETE BEAMS WITH BASALT FIBER REINFORCEMENT WITHOUT WEB REINFORCEMENT

  • 摘要: 通过对再生粗骨料取代率、剪跨比、配筋率为参考因素的玄武岩复材(BFRP)筋再生混凝土梁抗剪性能试验研究,分析梁的裂缝扩展和破坏模式以及再生粗骨料取代率、剪跨比和配筋率对试验梁抗剪承载力的影响,并将试验结果与中、美、日、加四个国家的技术标准推荐算式的计算结果进行比较。结果表明:BFRP筋混凝土梁主要发生两种剪切破坏,其中9根试验梁发生剪压破坏,2根试验梁发生斜拉破坏;BFRP筋混凝土梁挠度随BFRP配筋率和剪跨比的增大均减小,当再生粗骨料取代率为30%、60%时,BFRP筋再生混凝土梁挠度与BFRP筋普通混凝土梁差别不大;BFRP筋再生混凝土梁抗剪承载力低于BFRP筋普通混凝土梁;美国标准ACI 440.1R-15的计算值最保守,中国标准GB 50608—2010、日本标准JSCE 1997次之,而加拿大标准CSA.S 806-12在计算BFRP筋再生混凝土梁抗剪承载力时吻合度更好并具有安全度。
