考虑球冠形脱空影响的圆钢管混凝土柱抗侧向冲击性能分析

Jianzhu Gangjiegou Jinzhan
近年来钢管混凝土作为城市高架、跨河桥梁的墩柱常受到车辆、船舶等机械冲击灾害，是引发其结构损伤、破坏甚至严重倒塌的最主要因素之一。而实际钢管混凝土结构由于材料、施工、环境等因素普遍存在脱空缺陷问题，但目前尚缺乏关于带脱空缺陷钢管混凝土抗侧向冲击性能的相关研究报道。为此，建立了考虑球冠形脱空特征的圆钢管混凝土柱抗侧向冲击有限元分析模型，系统分析了脱空率、脱空方位、冲击速度、冲击质量、边界条件、轴压比、径厚比等参数对冲击力（包括峰值Fm和等效值Feq）、挠度变形（包括最大值δm和残余值δr）与能量吸收（Ea ...
