EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR OF RC BEAM STRENGTHENED WITH SELF-REPAIRING SMA/ECC COMPOSITES MATERIALS

  • 摘要: 为了提高既有RC构件的承载能力、损伤自修复能力,提升其安全与使用性能,该文提出采用超弹性形状记忆合金(Shape memory alloy, 简称SMA)和工程水泥基复合材料(Engineered cementitious composites, 简称ECC)复合加固钢筋混凝土梁的方法。设计并制作了4种试验梁以对比不同增强材料加固效果,通过低周单向循环加载试验,分析了不同材料加固试验梁的破坏形态、承载力、耗能性能和自修复能力等性能的影响。研究结果表明:SMA/ECC复合加固梁不仅提高了承载能力,且具有较好的延性和变形能力,同时具有优越的自修复性能。考虑ECC拉伸应变硬化特性,建立了ECC加固梁的受弯承载力计算方法,且计算值与试验值吻合较好。
