摘要:
为探究工程设计最优键齿深度h与键齿根部高度H比和键齿倾斜角度θ,研究超高性能混凝土(UHPC)大键齿胶接缝的直剪性能和破坏机制,本文进行了UHPC大键齿胶接缝直剪性能试验。基于试验验证的ABAQUS有限元模型(FEM),采用控制变量法和正交试验设计分析了侧向预应力σ、θ和h等参数对键齿试件破坏模式、破坏机制和抗剪承载力的影响,提出了UHPC大键齿胶接缝抗剪承载力计算公式。结果表明,大键齿胶接缝试件破坏模式主要可分为键齿根部的直剪破坏、沿胶接缝界面的滑移破坏和剪压破坏。工程设计应用中,UHPC大键齿胶接缝的h/H和θ建议取值分别为0.19≤h/H≤0.30,15°≤θ≤27°。不同侧向预应力水平、键齿倾斜角度、键齿深度下的抗剪承载力计算值与有限元值比值介于0.88~1.14,平均值为0.94。
