Bogazici University (TR)

Established in 1868 as the Imperial Observatory, KOERI was annexed in 1982 to Boğaziçi University with an institutional academic status. Today KOERI is among the leading organizations in earthquake in Turkey, providing graduate education, conducting research and developing applications in Earthquake Engineering, Geophysics and Geodesy. It consists of a staff of 75 academic and technical personnel. It embraces Regional Earthquake and Tsunami Monitoring Centre which operates more than 200 sensors at the national level as well as sea-floor multi-instrument observation systems in the Sea of Marmara.

Its Earthquake Engineering Department conducts research and implementation with a focus on: Earthquake hazard and risk analysis for major infrastructures and urban areas; Earthquake insurance; Earthquake resistant design and retrofit of structures; Characterization of strong earthquake ground motion. Observational studies include generation of earthquake rapid response and early warning information permanent dense strong motion networks and temporary strong motion instrumentation. KOERI has taken active roles in the MARSITE and EU FP7 projects NERA, REAKT, SHARE, TRIDEC, SERIES and STREST (ongoing).

KOERI has also worked extensively on the seismic protection of Cultural Heritage at sites such as Fatih, Mihrimah Sultan and Suleymaniye Mosques, Haghia Sophia museum in Istanbul. More specifically, it conducted earthquake performance research including: ambient vibration tests; non-destructive and destructive in-situ shear testing for the determination of material properties; linear and non-linear 2- and 3-dimensional finite element analyses; sub-surface and structural member investigations by geophysical methods.

Role in the Project

The BU/KOERI team has extensive experience in the earthquake hazard and risk assessment and risk mitigation/management in building and non-building structures. As KOERI we are planning to focus on the seismic related issues.

KOERI will lead the T9.3 Early Assessment and Final validation and mainly contribute in WP1 Fundamentals, Methodologies, and Processes, WP2 Recommendations for Policies and Government processes, WP4 Environmental, Sensing and Monitoring Toolset and WP5 Risk Management and hazard mitigation tools.

These correspond: current practices and processes for conservation of cultural heritage, earthquake risk assessment and management methodology. quick earthquake damage assessment methods, identification and quantification of earthquake hazard (all sites), potential earthquake vulnerabilities and risks, earthquake mitigation strategies, suggestions for strengthening, implementation plan and innovative tools for multi-dimensional risk assessment and management and policies.

More specifically, KOERI will investigate the dynamic behaviour of selected structure(s) during an earthquake which may be caused by a nearby fault in the region. In order to accomplish this task, the team will perform field surveys as well as use a number of advanced modelling and analysis tools to identify possible weaknesses and damage initiation points of the structure. The output of this work will be used to develop proper strengthening techniques to have safer and resilient historical assets. All tools, methods or procedures developed within this work is expected to be applicable to other sites or hazard types by some minor adjustments.
