FRP–Concrete Interface Bond Performance Dataset

This dataset contains experimental data collected from single-lap shear tests on FRP–concrete specimens subjected to varying numbers of freeze–thaw (FT) cycles. It includes geometric properties, material parameters, environmental conditions, and measured bond–slip responses. The dataset supports the development and validation of machine learning models for predicting key interfacial parameters such as peak shear stress, fracture energy, and slip capacities. It serves as a benchmark for durability evaluation and data-driven modeling of FRP–concrete bond performance in cold regions.
