Reinforcement of Stone Masonry Walls with Carbon Fiber Tissue and Tapes, a Case Study

Abstract:

The reconstruction project of an existing masonry building will be presented in this paper. The building was erected in 1911. The building has a ground floor and three floors. Its façade is protected as cultural heritage. Due to the conversion of the building into a hotel, a lot of interventions have to be done on the existing structure, which significantly changes the properties of the structure and increases the weight of the building, and thus seismic forces. Due to structural assessment, the project was preceded by different on site structural tests. A very detailed 3D FEM model with solid elements was created on which the analysis of the structure was carried out. The results of nonlinear analysis for vertical loads, modal (eigenvalue) analysis, response spectrum analysis and push-over analysis (nonlinear construction stage analysis “sequence analysis”) will be shown. Only when carbon fibers reinforcement was included in the FEM model, the vertical loads were applied. It can be activated for earthquake forces. The comparison between the results for unreinforced and reinforced structure proves increasing carrying capacity of the stone masonry walls after reinforcement with carbon fibers was combined with the masonry walls grouting.
