In this article, a Personal Computer (PC) based Finite Element (FE) model for identification of static behaviour of a built highway bridge is presented and its predictions are compared with in situ test results. The motivation behind this work is to improve the structural maintainability of existing bridges and to assess the consequences of a particular change proposal. It is demonstrated that a high speed FE-PC analysis can be accomplished for an urgent structural integrity assessment of the existing bridges, as well as for creating a database to monitor their structural propriety. Despite some anticipated inaccuracies within the modelling and analysing processes of an existing reinforced concrete bridge structure, it has been found that the present FE model, aboard a 486 DX2-66 MHz PC, is able to predict the maximum measured results of the field tests within an average error of 5.7 percent.
