Determination of Road Bridge Load -Carrying Capacity

In frame of global European standardization and as consequence of new knowledge concerning the existing bridge reliability, the need for revision of the Technological Standard No. 104 “Load-carrying capacity of road bridges and footbridges” [1] (hereinafter referred to as TS 104) had started up. In the first stage of the revision, the preparation and analysis in the form of Analysis Task (hereinafter referred to as AT) has been worked up by the collective of the Department of Structures and Bridges from the University of Zilina in cooperation with Slovak Road Administration (SRA), National Motorway Company (NMC) and other co-operators among academicians and designers. In the presented paper, the attention is paid to the general concept and basic assumptions of the AT and revised TS 104 for determining the road bridge load-carrying capacity.
