Seismic Assessment and Strengthening of an Existing Industrial Building

Nowadays, the development of rapid and low-impact structural rehabilitation strategies and techniques is very topical. These prerogatives are essential for the seismic retrofit of industrial buildings, for which the seismic retrofit solution should be selected also accounting for the impact of the interventions on the productive activities. Therefore, a retrofit solution that allows to increase the structural capacity without interfering with the industries production could be preferred with respect to canonical retrofit solutions. In this framework, the aim of the present work is to investigate the efficiency of orthogonal steel exoskeletons for the retrofitting of a steel single-storey industrial building. The investigated case study has poor lateral stiffness and strength. Following a specific design methodology, the various elements of the system were designed, and their efficiency was assessed by means of a non-linear static procedure. Moreover, a local retrofit of the truss to column connections of the MFRs was performed and investigated by means of FEM analysis.
