Data underlying the research on Tensile Test and Finite Element Optimization of the Triple-pipe Rebar Connector

The dataset from the study "Tensile Test and Finite Element Optimization of the Triple-pipe Rebar Connector" includes comprehensive graphical representations of its mechanical performance. This encompasses the **Connector Load-Strain Curves** obtained from the physical tensile tests, which detail the elastic, yielding, and strain-hardening behavior of the assembly. The finite element analysis contributed two key sets of results: the **Load-Strain Curves of Connector Steel**, illustrating the simulated material response of the connector itself, and a **Comparison of Rebar Load-Strain Curves**, which directly validates the FEA model against experimental data by overlaying the predicted and measured performance of the rebar. Additionally, the structural response is further characterized by the **Connector Load-Displacement Curves**, providing essential information on stiffness and deformation characteristics until failure.
