    Bridge Concept Applied To Rehabilitate An

    NTEGRAL BRIDGE CONCEPT APPLIED TO REHABILITATE AN
    EXISTING BRIDGE AND CONSTRUCT A DUAL-USE BRIDGE
    R. Jayaraman, PB Merz and McLellan Pte Ltd, Singapore



    Abstract

    In this article two case studies are presented where the integral bridge concept
    has been advantageously adapted: strengthening of an existing bridge & construction
    of a new dual-use bridge. During the investigations, assessment & upgrading of an
    existing prestressed concrete bridge over a tidal river, a number of proposals for
    strengthening the bridge to carry heavier vehicular loads were studied. Conversion of
    the existing simply supported deck to be integral with abutments was found to suit the
    site conditions. Effectiveness of strengthening were confirmed by monitoring system
    using strain gages & accelerometers. In the second case integral bridge concept was
    successfully implemented in a D & B contract. This dual use bridge across a canal
    carries six circuits of 400kV lines at soffit level and would be carrying road traffic in
    the transverse direction in the future. The integral bridge using two precast posttensioned
    girders connected by cast in-situ diaphragms and deck slab presented
    many interesting features.
