The Eight article in the series on design and construction of concrete bridges, explores the subject of prestressing as it concerns concrete bridges.
Tag: Concrete Bridges
This fifth installment on the series on concrete bridges provides insights on the maintenance and management of concrete bridges.
Precast bridges are highly favoured, where the speed of construction is very crucial or generally where the cost of procuring precast is justified by a shorter construction programme. This article discusses the different forms of precast bridges, typically encountered in practice.
Whilst construction methodology tends not to be an issue in many buildings, the same cannot be said for bridges. Nearly all bridges cannot and should not be designed without good knowledge of its temporary stages and construction methodology4. In most cases it is the construction method that determines the design. In selecting the best scheme, a bridge designer would aim to select a construction method and a bridge layout as they are basically entwined.
Deciding the final choice of a bridge requires serious considerations, and depends important parameters, many of which correlates between construction program, cost and risk.
This is the first post in a series on concrete bridges, the series will discuss in detail the various aspects of concrete bridge design and construction. This post introduces the concept and the key benefits of using concrete for bridges
