| 中文摘要: |
| 从桥梁结构多尺度损伤有限元模拟的研究需要出发,结合桥梁工程项目背景,利用相似模型实验的理论、方法,对桥梁结构中包含焊连接细节的钢桁架结构相似模型试样的设计、制作安装和实验方案等方面进行了研究;并在对拟实验的钢桁架模型试样进行初步有限元分析的基础上,确定了实验研究的载荷工况和测试方案. |
| 英文摘要: |
| This paper aimed to determine the method and approach of experimental study of steel truss sample for the purpose of multi-scale modeling of bridge damage. With Tsing ma bridge as the background, the design and experiment approach of steel truss including welded details in bridge structure were made by means of truss modeling with similarity theory. Based on the present research and finite element analysis, the load mode and testing scheme were confirmed. |
