An AHP model for multiple-criteria prioritization of seismic retrofit solutions in gravity-designed industrial buildings

This paper deals with the development of an Analytic Hierarchy Process (AHP) model aimed at driving decision-making processes when dealing with seismic retrofitting of industrial buildings. Particularly, the model considers not only the output of seismic analysis and engineering evaluations, but also socio-economic aspects, such as production downtime, through proper weighting operations. To validate the model, a case-study is used, which consists in the analysis of three alternative retrofitting solutions for one-story building, with a simple and geometrically regular structural scheme and realized with reinforced concrete precast elements. The results obtained here demonstrate the ability of the model to capture both technical and economic aspects, and its adaptability to reach different objectives too, such as energy retrofit
