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.

本研究《三重管钢筋连接器的拉伸试验与有限元优化》所采用的数据集，涵盖了该连接器力学性能的全套可视化图表表征。其中包含由物理拉伸试验（tensile test）测得的**连接器荷载-应变曲线（Connector Load-Strain Curves）**，该曲线详细刻画了该连接器组件的弹性、屈服及应变硬化力学行为。有限元分析（Finite Element Analysis，FEA）提供了两组核心结果：其一为**连接器钢材荷载-应变曲线（Load-Strain Curves of Connector Steel）**，用于展示连接器本体的模拟材料响应；其二为**钢筋荷载-应变曲线对比图（Comparison of Rebar Load-Strain Curves）**，该对比图通过叠加钢筋的预测性能与实测性能，直接将FEA模型与试验数据进行验证比对。此外，该数据集还通过**连接器荷载-位移曲线（Connector Load-Displacement Curves）**进一步表征了结构响应，提供了直至失效前的刚度与变形特性相关的关键信息。
