Dataset of bond strength between FRP bars and seawater sea sand concrete (SWSSC)

In order to investigate the bond strength between FRP bars and seawater sea sand concrete (SWSSC) effectively, 292 experimental data acquired from pullout tests were collected from relevant research papers. It should be mentioned that for the scope of dataset, the failure mode of pullout tests is pullout failure excluding concrete splitting failure. The 13 input parameters (Concrete compressive strength, Cement-to-binder ratio, Seawater-to-binder ratio, Sea-sand-to-binder ratio, Coarse-aggregate-to-binder ratio, Maximum particle size of CA, Bar diameter, Rib-spacing-to-diameter ratio, Rib-height-to-diameter ratio, Bar surface treatment, Bonded-length-to-diameter ratio, Bar fiber type, Bar tensile elastic modulus) were selected to study the effects of mechanical property and composition of SWSSC, along with the mechanical, geometric, and surface properties of FRP bar on bond strength. The developed dataset can serve as an effective resource for investigating the bond strength between FRP bars and SWSSC.

为有效探究纤维增强塑料（FRP）筋与海水海砂混凝土（SWSSC）之间的粘结强度，研究人员从相关学术文献中搜集了292组拉拔试验的实测数据。需说明的是，本数据集仅纳入拉拔试验的拔出破坏模式，排除混凝土劈裂破坏的试验样本。本次研究选取了13项输入参数，具体包括混凝土抗压强度、水泥与胶凝材料用量比、海水与胶凝材料用量比、海砂与胶凝材料用量比、粗骨料与胶凝材料用量比、粗骨料最大粒径、筋材直径、肋间距与直径之比、肋高与直径之比、筋材表面处理方式、粘结长度与直径之比、筋材纤维类型、筋材拉伸弹性模量，以分析海水海砂混凝土的力学性能与组成成分，以及纤维增强塑料筋的力学、几何与表面特性对粘结强度的影响。本数据集可为纤维增强塑料筋与海水海砂混凝土的粘结强度研究提供有效支撑资源。
