Title: DESIGN AND PERFORMANCE OF INTEGRAL ABUTMENT BRIDGE IN ONTARIO
Abstract: Integral abutment bridges are single span or multiple span continuous deck type bridges with a movement system composed primarily of abutments on flexible integral foundations and approach slabs, in lieu of movable deck expansion joints and bearings at abutments. This paper outlines Ontario's use of this bridge type. Guidelines regarding planning, design, detailing and construction are provided. Advantages and disadvantages of the bridge type are discussed. A review of the actual performance of a number of existing bridges is provided. Recommendations for improvements with respect to provision for thermal movement and reduced maintenance are given.
