Reinforcement of brick historic buildings threatened by structural damages or by failure

Abstract

The paper presents selected aspects of reinforcing the brick cultural heritage buildings, particularly load-carrying elements of those structures. In some cases the operational phase of many load-bearing elements of the historical buildings is shrinking or has used up. The crucial task while carrying out construction works related to reinforcing or repair of the load-bearing structure is to ensure safety. This safety should be assured regarding both the structure itself and its users. The design concept also needs to include recommendations and instructions of the conservatorinspector. The proposed scope of technical assessment and analysis of the load-bearing structures of buildings is presented on selected examples. The performed diagnostics process allowed to properly determine the occurred hazards and on this basis to properly design and carry out repair of damaged elements of structure [1]. The first of the analysed cases concerns the barracks facility near the Makowiecka Street in Przasnysz. Another example described in this paper is the brick dome of the church building of St. Anne in Wilanów district in Warsaw. The damages and failure identification process, as well as taken measures and proposed methods of reinforcement of the structure are presented with reference to the both above mentioned examples.
