This article discusses the great advantages of using steel sheet piled abutments and jointless integral designs in road bridges. Reinforced concrete bridges are too vulnerable to deterioration, which usually results from corrosion of the reinforcement due to penetration of deicing salts. Often, chlorides enter poor or failed expansion joints. Thus many bridge engineers propose to design bridges to function without the need for movement joints or bearings. In such designs, load-bearing abutments, in concrete or sheet steel piling, are joined directly to the composite or reinforced concrete deck structure. Steel substructures have several significant advantages, including freedom from cracking and potential for more compliant bending. Such designs offer lower maintenance costs and greater long-term reliability. Aiming to reduce operating costs, the Department of Transport (DoT) recently published Advice Note BA42/95, which advocates the consideration of integral designs for most bridges up to 60m total length. The Steel Construction Institute will soon publish its "Design Guide for Composite Integral Bridges", with detailed advice on using steel sheet piled abutments. Such bridges have been widely used for many years in several countries, especially in the USA and Australia, but are only beginning to be built in the UK.
