BUILDING MONITORING FOR SEISMIC RISK ASSESSMENT (I):INSTRUMENTATION OF RC FRAME STRUCTURES AS A PART OF THE SERAMAR PROJECT
The main objective of the SERAMAR project (Seismic Risk Assessment and Mitigation in the Antakya-Marao Region) is to utilize current tools for earthquake risk assessment and to establish a unique partnership between universities, professional associations as well as local governments that might serve as a model for similar future activities in Turkey and adjacent areas. In order to reach this goal a thorough microzonation including vulnerability and social preparedness studies in forefront of a damaging seismic event have to be conducted.In the first phase of the project, the entire building stock was surveyed and classified on the basis of the European Macroseismic Scale EMS-98. Following the principles of this empirical approach, the most likely and probable ranges of vulnerability classes have to be identified. In addition, predominant building types and their structural layout are elaborated in advance of nonlinear time-history and pushover analyses.In this context, the instrumental investigation of buildings being representative for the study area becomes an essential part of the project to calibrate the models and to predict reliable capacity curves as well as scenario-dependent damage pattern or failure modes. The latter should be suited to derive mitigation strategies.Based on different decision criteria, three multistory RC frame structures have been chosen and equipped with modern Seismic Building Monitoring Systems (BMS) each of which consists of four triaxial strong-motion accelerometers of type MR2002+. After a 2 year test period, first results from the permanent instrumentation are available and provide a preliminary basis to reinterpret the structural response under seismic action.
