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.


Steps to reproduce

A search on steel-to-concrete bond degradation after exposure to elevated temperatures was carried out via SCOPUS in January 2019. As a result 17 references were found, which have been studied in order to (1) identity the potential variables or parameters that affect bond strength at high temperature and (2) prepare a comprehensive database including the values of these variables and those that describe the evolution of the bond strength at high temperature.
