101-0194-00L Seismic Evaluation and Retrofitting of Existing Buildings
|Periodizität||jährlich wiederkehrende Veranstaltung|
|Kurzbeschreibung||The aim of this course is to present the state of the art of the current procedures for seismic evaluation and retrofitting of existing buildings in Switzerland (Norm SIA 269/8) and worldwide. Emphasis will be given on the practical application of these procedures in real buildings located in Switzerland, through case studies presented by experts in the field.|
|Lernziel||A large percentage of the existing building inventory worldwide has been constructed before the introduction of the current seismic code provisions. The seismic deficiencies observed in many of these structures are a direct outcome of their non-compliance with these provisions and the established engineering practices in seismic design. Moreover, the unavoidable material deterioration in these structures could further inhibit their seismic performance. Therefore, the knowledge of the current procedures and common practices for the seismic evaluation and retrofitting of buildings is of paramount importance. This course presents an overview of these procedures through a wide spectrum of applied case studies in Switzerland and worldwide. The students will work on a project related to the presented case studies, thus obtaining deep understanding on the application of these procedures and a feeling on how to engineer practical retrofitting strategies towards the seismic upgrading of existing buildings.|
