Dataset of bond strength and failure mode between FRP bars and UHPC or UHPSSC

In order to investigate the bond strength and failure mode between fibre-reinforced polymer (FRP) bars and ultra-high-performance concrete (UHPC) & ultra-high-performance seawater sea sand concrete (UHPSSC) effectively, 542 experimental data acquired from pullout tests were collected from relevant research papers. The failure modes consist of pullout failure and concrete splitting failure. 14 input parameters (Vf of steel fibre, Vf of PP/PE fibre, Concrete type, Concrete compressive strength, Water-to-binder ratio, Sand-to-binder ratio, Bar diameter, Cover-to-diameter ratio, Bonded-length-to-diameter ratio, Rib-spacing-to-diameter ratio, Rib-height-to-diameter ratio, Bar surface treatment, Bar fibre type, Bar tensile elastic modulus) were selected to study the effects of mechanical property and composition of UHPC/UHPSSC, along with the mechanical, geometric, and surface properties of FRP bar on bond strength and failure mode. The developed dataset can serve as an effective resource for investigating the bond strength and failure mode between FRP bars and UHPC/UHPSSC.

为有效探究纤维增强聚合物（FRP）棒与超高性能混凝土（UHPC）及超高性能海砂混凝土（UHPSSC）之间的粘结强度及其破坏模式，从相关研究论文中收集了542组通过拔出试验获得的实验数据。破坏模式主要包括拔出破坏和混凝土开裂破坏。选取了14个输入参数（钢纤维体积率Vf、PP/PE纤维体积率Vf、混凝土类型、混凝土抗压强度、水胶比、砂胶比、棒直径、保护层厚度与直径比、粘结长度与直径比、肋间距与直径比、肋高与直径比、棒表面处理、棒纤维类型、棒拉伸弹性模量），以研究UHPC/UHPSSC的力学性能和组成，以及FRP棒的力学、几何和表面特性对粘结强度和破坏模式的影响。该数据集可作为研究FRP棒与UHPC/UHPSSC之间粘结强度及破坏模式的有效资源。
