Leader of Working Group 4 – Capacity Building of the WFEO-CDRM\, United Kingdom\n\n\nIn the first pres entation of this session\, Maria will introduce the fundamental aspects of a novel analytical framework for assessing the performance of reinforced concrete (RC) structures subjected to dry granular flows. The soil pressur es acting on rigid structures are initially identified through a 3D Materi al Point Method (MPM) model of a flume experiment. The model is adapted to simulate a building by replacing the retaining wall with a reduced-width obstacle\, allowing for the investigation of the impact of blockage ratio on force distribution. The recorded soil forces are then applied to a 3D R C frame building in OpenSees\, facilitating both static and dynamic analys es. The results demonstrate the adequacy of adopting a practice-oriented s tatic approach for evaluating landslide induced structural damage. Maria w ill conclude her presentation by highlighting the significant differences in structural behavior under landslide and seismic loads.\n\nSahin will fo llow this presentation by addressing the findings of an extensive research project on the seismic vulnerability of high-rise tunnel-form buildings\, a prevalent building typology used in mass housing projects in seismicall y active regions\, such as Türkiye. His ongoing research project synthesi zes a sophisticated numerical model\, multi-staged verification protocols\ , and post-earthquake field observations to examine the seismic performanc e of tunnel-form buildings. The salient structural features of the typolog y\, nuances in numerical modelling\, observed damage mechanisms following the 2023 Türkiye earthquakes and an overview of the fragility framework a dopted in this research project will be discussed.\n\nFinally\, Harikesan ’s presentation will cover the growing need to understand the vulnerabil ity of the green economy to natural hazard events. Given the complexity an d low exposure history of these assets\, assessing their vulnerability pos es a major challenge for the insurance industry. In his talk\, Harikesan w ill provide an overview of a systematic literature review conducted as par t of a UCL-AXA collaboration\, which determined the suitability existing l iterature for this purpose. It will be followed by an overview of his curr ent PhD research looking at the vulnerability of onshore wind turbine gear boxes to extreme wind events – a critical area in need of further resear ch.\n \;\nFor more information:\n\n Webinar presentation in CIP websit e\n\n ATTACH;FMTTYPE=image/jpeg:https://www.wfeo.org/wp-content/uploads/CDRM-web inar_2025-01-10.png CATEGORIES:WFEO event,WFEO member event END:VEVENT BEGIN:VTIMEZONE TZID:Europe/Paris X-LIC-LOCATION:Europe/Paris BEGIN:STANDARD DTSTART:20241027T020000 TZOFFSETFROM:+0200 TZOFFSETTO:+0100 TZNAME:CET END:STANDARD END:VTIMEZONE END:VCALENDAR
