Multi Criteria Decision Making Tool for the Selection of Seismic Retrofitting Techniques
نویسندگان
چکیده
Upgrading existing buildings to meet current seismic design codes is important in high seismic hazard regions. Decision makers must choose from many possible retrofitting options, each with inherent advantages and disadvantages. The two main decision drivers that are commonly used are: increasing engineering performance (ductility, strength, etc.) and reducing cost. There is currently little information that incorporates socio-economic factors (e.g., aesthetics, sustainability) into the decision making process. The aim of this paper is to develop a multi criteria decision making tool that takes both the engineering and socio-economic factors into consideration for retrofit selection. Since the importance of each factor varies based on building type, location, and attitude of the decision makers, OWA operators will be utilized. As well, for multiple decision makers, credibility factors will be introduced. This model can be expanded in the future to incorporate new retrofitting techniques and selection criteria.
