Abstrait: | Describes the construction of a 480-ft long precast, post-tensioned concrete, inverted suspension bridge which was recently constructed near San Jose, Costa Rica. This functional and economically built bridge shows how, with some ingenuity, the principles of suspension, arch, and cantilever theory can be applied with relatively simple construction techniques to span a deeply inclined canyon in remote and very rugged terrain. Initially, the piers of the bridge were built vertically. They were then rotated 30 deg so that they could provide beneficial arch and cantilever action and also to insure a safe foundation. Precast concrete segments form the soffit along the suspended cables. In turn, the soffit was used as a working platform on which precast bents and roadway beams were erected. This article describes the construction sequence of the bridge erection with the aid of diagrams and photographs. |
