Abstract

The building of Diocese is located in the very center of Pančevo, at the very corner of the City Park. The object is of a great historic and cultural importance and it has been already in use for two centuries. The object was built in the masonry system, using stones and bricks for the walls, and timber for the floor and roof structure. This paper gives the description of repair and reconstruction of timber floors of 6,5m, by coupling timber and concrete technique. The detailed design concept is shown, based on the theory of coupling elasticity and the concepts of ultimate and serviceability limit state of timber structures (Eurocode 5). For the accepted design model, its numerical verification was carried out by the proper simulation in software ABAQUS 6.11. For timber, concrete and adopted fasteners for their coupling, certain laws of material behaving were adopted, as well as their evaluated and proved mechanical characteristics. All this was done to carry out design procedure. The obtained comparative results were presented, from the aspect of nonlinear stress strain analysis in characteristic sections and zones of applied design model. Finally, a short review of reconstruction based on the previous theoretical-analytical observations was given.
