Abstract

The development of appropriate tools to assess the actual structural performances taking into account also seismic actions and to design and execute interventions capable to improve such performances, is a key issue in the field of conservation and valorisation of architectural heritage. In the paper are presented the results of five full scale destructive tests that have been performed on an historical building in Verona, the St. Peter’s Castle, located on the top of the hill over the city. Several constructions were erected in that place during centuries and the current building dates back to the 19th century under the Habsburg Empire. The first aim of this research is to evaluate the behaviour in the original construction of those barrel vaults 5.6m span, 1.1m rise and 27 cm thick. Despite the common tests available in literature this experimentation is not performed on reconstructed vaults,which uses different materials and technologies compared to the historical ones but which can show the actual behaviour. Moreover the analysis of details underlines their key roles in the structural behaviour even affecting the final failure mechanism. A brief presentation about the design of the dedicated testing set-up it is reported. In addition, the second goal of the work concerns the evaluation of four strengthening solutions varying among nets, organic and inorganic fibres applied with both type of matrix as well. A better understanding of these interventions, taking into account as well the main issues of the refurbishment is shown in this work.
