Dataset for Temperature Development in Ultra-High-Performance Concrete-Filled Double-Skin Tubes Exposed to Fire

This dataset presents extensive experimental data available in the literature for concrete-filled tubes (CFT) and ductile concrete-filled double-skin tubes (CFDST) exposed to fire. Different concrete grades, including normal strength (NS), high strength (HS), and ultra-high-strength (UHS) concrete, were tested, and the temperature developments within various cross-sections are provided in the supplementary data. The density, specific heat, and conductivity that are temperature-dependent, are documented by different researchers and current specifications. The preferred models are provided for carbon-steel, stainless-steel, and different grades of concrete. Numerical studies such as those conducted by the authors in a companion paper would find value in this data for validation and verification purposes本数据集收录了公开文献中针对受火作用下钢管混凝土（Concrete-Filled Tubes, CFT）及延性双层钢管混凝土（Ductile Concrete-Filled Double-Skin Tubes, CFDST）的大量试验数据。试验涵盖普通强度（Normal Strength, NS）、高强度（High Strength, HS）与超高强度（Ultra-High-Strength, UHS）等不同强度等级的混凝土；补充数据中提供了各类截面内部的温度变化历程。不同研究者及现行规范均记录了随温度变化的密度、比热容与导热系数。本数据集针对碳钢、不锈钢及不同强度等级的混凝土给出了推荐模型。诸如配套论文中作者开展的数值研究，均可依托本数据集完成验证与校核工作。
