| 摘 要： | 针对传统单管塔结构易发生底部截面破坏且不易修复的特点,借鉴自复位和易修复的概念,通过引入预应力技术和设定破坏装置,提出一种易修复输电单管塔结构。该单管塔结构在极端荷载作用下能够在保护主体结构不受损坏的前提下在设定部位发生破坏,设定损坏截面的设定破坏装置损坏后可以快速更换,从而实现整体结构的易修复性能,符合以可持续发展和循环经济为核心的绿色建造的理念。首先提出易修复单管塔结构的概念设计,对影响易修复单管塔结构力学性能的因素进行了理论分析,并通过单调推覆加载试验和有限元对理论分析进行验证。

| Abstract: | This paper develops an easy-maintenance transmission steel pole structure with a self-centering feature by introducing prestressing technology and a specified device. Under extreme loading conditions, the structure fails at a specified location so to protect other components. Additionally, the specified device is designed to be replaced conveniently after it is damaged, so it entitles the structure the feature of easy-to-repair. The new design contributes to green construction and sustainable development by reducing the entire structural damages of the power transmission lines. In this paper, a flow chart for this newly easy-maintenance transmission steel pole structure is proposed. Structural behaviors of this new design are studied through theoretical analyses and pushover testing. |
