Tensile experimental data from monotonic loading on connections to concrete filled steel tubes using Extended Hollo-bolt blind bolts

This dataset is related to the research paper entitled “Fusion of Experimental and Numerical Data for Development of Extended Hollo-bolt Component Based Model” published in the Engineering Structures journal (Cabrera et al., 2024). It provides the necessary information for the collection of tensile load-displacement data from Concrete-filled Steel Tubes (CFST) connected to a rigid T-Stub using Extended Hollo bolts (EHB). The dataset encompasses (i) the load-displacement response of 28 EHB connections subjected to monotonic tensile tests, which include displacement data at the bolt head, bolt end, and column face; (ii) 40 pictures per sample taken at fixed intervals during the tensile testing, along with 2 pictures after failure, one before and one after careful removal of the top plate of the steel tube which facilitate the understanding of concrete damage and failure mode. This information is intended to provide insights into the failure mechanism of the EHB connections when components can interact and contribute to deformability of the connection as well as provide full data for development and validation of predictive models such as numerical, analytical, and data driven models.
