钢桥裂纹扩展规律及数值模型数据集

本数据集由钢桥面板典型构造裂纹扩展试验数据、基于热点应力的钢桥典型焊缝的疲劳强度数据集和基于Paris公式修正的裂纹扩展试验数据组成，包含了用于裂纹扩展规律研究的15个局部试件的试验数据、用于热点应力研究的60个局部试件的试验数据和用于裂纹扩展模型研究的10个局部试件的试验数据，以及用于横隔板-U肋细节热点应力研究的ABAQUS有限元模型。

This dataset consists of three categories of experimental data and one ABAQUS finite element model. The first category is crack propagation test data for typical details of steel bridge decks, which includes experimental data from 15 local specimens used to study crack propagation laws. The second category is fatigue strength datasets of typical welds in steel bridges based on hot spot stress, containing experimental data from 60 local specimens for hot spot stress research. The third category is crack propagation test data modified based on the Paris formula, covering experimental data from 10 local specimens for crack propagation model development. Additionally, it encompasses the ABAQUS finite element model for studying the hot spot stress of diaphragm-to-U-rib details.
