| 摘 要： | B型梁是目前应用较广的小跨度多用途拆装式钢梁,文中利用Midas/Civil建立24mB型梁有限元模型,分别计算了自重和中-活载作用及荷载组合下的位移和应力、梁体的自振特性。通过比较分析表明:B型梁位移、应力均达到设计要求,符合规范规定。 |
| 关 键 词： | B型梁 有限元 空间模型 静力分析 自振特性 |

| Abstract: | For present time, B type girder is a widely applied removable small span steel girder. Via Midas/Civil, a 24m B type girder finite-element model is introduced in this thesis. Based on this model, self weight calculation, middle-live load function, further displacement & stress under load combination, girder body's natural vibration characteristic are described respectively. Through these comparison and analysis, a conclusion can be obtained that the displacement and stress of B type bridge girder meets the ... |
