The Design of Prestressed Concrete Bridges: Concepts and Principles

This book is intended to help designers of concrete bridges to develop anunderstanding of their structural action. The principles of prestressed concrete are explained by following step-by-step the preliminary design of a simple beam and a continuous beam. The logic underpinning the shape of concrete bridge decks is described and direct guidance on the choice and sizing of different types of deck is given. The construction methods appropriate to each form of deck are detailed. The topics covered in the chaptersare: the nature of design; basic concepts; reinforced concrete; prestressed concrete; prestressing for statically determinate beams; prestressing for continuous beams; articulation of bridges and the design of substructure; the general principles of concrete deck design; the design of bridge deck components; precast beams; solid slabs, voided slabs and multi-cell boxgirders; ribbed slabs; box girders; counter-cast technology for box section decks; the construction of girder bridges; the effect of scale on the method of construction; the design and construction of arches; and cable-supported decks.
