Abstract

This work is concerned with a rehabilitation project of an old nailed-laminated timber arch roof of 17,80 m span . The arch is tied by four steel rods . Two of these rods are horizontal , one of which is placed between the supports and the second one is at the mid- height of the arch. The other two rods are diagonals and run from the supports up to the arch sections placed at 0,8 of arch height. During remodeling of the structure , acoustic insulation layers were placed on the arch, starting from one of the supports to the crown. Due to the imposed overload, an excessive deflection in asymmetric shape happened. As result, one of the diagonal steel bars suddenly failed. Having in mind the light state of deterioration of wood, the project of recuperation of the timber arch was carried out. A structural model was developed to evaluate the effects of the asymmetric overload imposed on the structure . The processes employed in situ to recuperate the original geometry of the arch, as well as the details of the strengthening project are also shown. Concluding remarks are given at the end of the work.
