Bridge strengthening is frequently associated with a long-term expensive bridge reconstruction. Although maximal bridge capacity is sufficient for standard traffic, it can be easily exceeded in the case of extremely heavy vehicles. Such vehicles typically weigh over 200 tons. Well-known bridge strengthening technologies are inefficient and ineconomical for this special load case. This paper presents a short-term bridge strengthening method using a temporary support structure for the assistance of the bridge carrying structure. Although this strengthening method is rather old, it is rarely known. The old theory from 1980, which is still often used, describes these temporary strengthening methods. The basic ideas come from very simplified principles and approximation models. This approximation causes restricted efficiency of the strengthening system and creates a mathematical model which does not have to be safe. The presented new short-term bridge strengthening theory is based on monitoring of real bridge structures and temporary support structures during the crossing of extremely heavy vehicles. A mathematical model, which represents behaviour of real structures aptly, is introduced. The major effects, which have the greatest influence on this strengthening method, and a safety hydraulic element invented at Brno University of Technology, which can be put into the strengthening system, ensure the required conditions and a guarantee of the strengthening system. © 2019 by the fib.
