Connection stiffness effects in a mechanically joined timber–timber composite bridge: Data and supporting files

This dataset supports the article “Connection stiffness effects on the global response and structural design of a mechanically joined timber–timber composite bridge.” It contains the data, numerical models, processing scripts, and design calculations associated with a full-size timber–timber composite (TTC) bridge composed of CLT panels connected to glulam beams through mechanical fasteners. The dataset includes geometric and loading information for the tested bridge; raw and processed quasistatic and dynamic experimental measurements; MATLAB scripts for dynamic signal processing and figure generation; SAP2000 finite element models representing different deck-to-beam connection stiffness assumptions; and spreadsheets used for experimental–numerical comparison and structural verification. The experimental and numerical results enable assessment of how deck-to-beam connection stiffness influences the global response of the bridge and the resulting structural design checks. The repository is intended to support transparency, reproducibility, and reuse of the results reported in the associated publication.本数据集支撑研究论文《机械连接式木-木复合桥梁的连接刚度对整体响应与结构设计的影响》。 本数据集包含全尺寸木-木复合（TTC）桥梁相关的数据、数值模型、处理脚本与设计计算，该桥梁由通过机械紧固件连接至胶合层积梁（glulam）的正交胶合木（Cross-Laminated Timber，CLT）面板组成。 本数据集涵盖受试桥梁的几何与荷载信息、原始及经处理的准静态与动态实验测量数据、用于动态信号处理与图表生成的MATLAB脚本、代表不同桥面-梁连接刚度假设的SAP2000有限元模型，以及用于实验-数值对比与结构验证的电子表格。 实验与数值结果可用于评估桥面-梁连接刚度如何影响桥梁整体响应，以及由此产生的结构设计校核流程。 本数据集仓库旨在提升相关论文所报道结果的透明度、可复现性与复用性。
