Abstract:  
Steel bridges which are designed adequately by the stength and deflection criteria are to be further checked for the length of the service life of various components (also known as details). These components such as cleats, gussets, bolts, rivets, welds, and stiffeners are to be individually assessed for their service life under fluctuating stresses caused by moving vehicles with varying axle weights. The details are classified in accordance with their importance. This paper describes the identification of the details to be assessed (hot spots) in steel bridges so that these can be strengthened to achieve full service life.
