Abstract

An efficient method for evaluating the safety of existing girder bridges as a function of the load and resistance parameters is presented. The bridge capacity is determined using a nonlinear finite element program in terms of the truck load which is increased until structure collapse occurs. It is determined that the reliability of fully prestressed bridges is higher than that of partially prestressed bridges, with the bridge system reliability is one-and-half to two times the girder reliability index. It is also found that the system reliability is more sensitive to accidental or local damage of the exterior girders than the interior ones.
