Abstract

Suspended footbridges are lightweight structures that are frequently constructed to create permanent connections in rural parts of the world. Their low weight (compared to that of other structural types such as trusses and beams) also makes them appealing for temporary projects requiring rapid deployment using minimal labor. The objective of this paper is to present a method for rapid deployment of suspended footbridges. The method incorporates prefabricated bridge components and manual drone deployment. Bridge deployment can be conducted when only one side of a crossing is initially accessible. First, a series of bridge pre-deployment, deployment, and disassembly steps are described. Then, the details of two full-scale polyester-rope suspended footbridge prototypes constructed with the method are presented. The prototypes demonstrate that the construction method can be executed by two people and is feasible for spans up to at least 13.1 m. The presented method is versatile enough that it can be adapted for the deployment of other rope structures.

摘要

悬挂式人行天桥是轻型结构，通常被构造为在世界农村地区建立永久连接。它们的重量轻（与桁架和横梁等其他结构类型的重量相比）也使其吸引了临时项目，这些项目需要使用最少的劳动力即可快速部署。本文的目的是提出一种快速部署悬空人行天桥的方法。该方法结合了预制桥组件和手动无人机部署。当最初只有交叉口的一侧可以到达时，才可以进行桥梁部署。首先，描述了一系列桥接预部署，部署和拆卸步骤。然后，详细介绍了用该方法构造的两个全尺寸聚酯绳悬式人行天桥原型。原型表明，该施工方法可以由两个人执行，并且对于跨度至少为13.1 m的情况是可行的。所提出的方法足够通用，可以适用于其他绳索结构的展开。
