Database of experimental results for steel-to-concrete bond at high temperature

This database contains experimental results that have been collected on steel-to-concrete bond strength after high temperature exposure. The results are sourced from a state of the art based on the available scientific literature in January 2019. The total number of references is 17, making a total of 466 experiments. The variables that have been identified are the following: • Type of fibre addition. • Fibre content expressed as percentage of volume fraction. • Concrete compressive strength at ambient temperature. • Bond length to rebar diameter ratio. • Clear concrete cover to rebar diameter ratio. • Age at testing. • Ratio between the duration of the thermal saturation at maximum temperature and the minimum specimen size squared. • Maximum exposure temperature. • Normalised bond strength, ratio between the bond strength after high temperature exposure and the original bond strength at ambient temperature. • The compressive strength after high temperature exposure, whenever the experiments covered this type of test. • The original peak bond strength value at ambient temperature. Also included, there is a tabulated representation of the main features of each experimental research.本数据库收录了高温暴露后钢-混凝土粘结强度（steel-to-concrete bond strength）的相关试验结果。本数据集的试验数据源自2019年1月梳理的全部公开科学文献，代表该领域当前的前沿研究水平。共纳入17篇参考文献，涵盖466组完整试验。 已明确的试验变量如下： • 纤维添加类型 • 以体积分数百分比表征的纤维掺量 • 常温混凝土抗压强度 • 锚固长度与钢筋（rebar）直径之比 • 混凝土净保护层厚度与钢筋直径之比 • 试验龄期 • 最高温度下热饱和时长与试样最小尺寸平方的比值 • 最高暴露温度 • 归一化粘结强度（normalised bond strength）：即高温暴露后粘结强度与常温原始粘结强度的比值 • 高温暴露后的混凝土抗压强度（仅当试验包含该测试项时提供） • 常温下的原始峰值粘结强度值 此外，本数据集还以表格形式呈现了每项试验研究的核心特征。
