| 摘 要： | 目前钢管混凝土拱桥虽然建设了不少,但在钢管混凝土的剪切滑移的研究和认识方面还存在一定的不足,该文对短期静力荷载作用下的钢管与混凝土界面接触进行了研究,建立了节段模型,对剪切滑移的ANSYS实体模型进行了介绍,并分析了两相邻吊杆间的单肢拱肋的时间历程响应曲线,得出了荷载从初始加载至达到极限承载力时拱肋位移的变化规律及各主要阶段的接触状态。 |
| 关 键 词： | 钢管混凝土拱桥 剪切滑移 接触状态 变化规律 |

| Abstract: | Though concrete-filled steel tube arch bridges have been built many at present,there are still deficiency in the study of steel tube and concrete.This paper analysed interfacial contact between steel tube and confined concrete under short-term static load,built section modal.ANSYS solid model was introduced and used to analyze single limb arch rib between two adjacent suspenders,sliding distance and time history response curve was got by applying monotonic increasing load.The changing laws of arch rib and t... |
| Keywords: | steel tube confined concrete arch bridge shearing and slippage contact state changing law |
