DESCRIPTION:Speaker bio\n\nMaria is a Research Associate in the Structures
  Group. Her primary interest lies in the development of more reliable meth
 ods for the design of structures to resist extreme events\, particularly e
 arthquakes and blasts. Her research experience spans from earthquake engin
 eering to structural robustness\, across a wide range of structural system
 s\, including steel and reinforced concrete buildings\, masonry constructi
 on\, and non-structural components. She holds a PhD and an MSc from Imperi
 al College London\, and an MEng from Aristotle University of Thessaloniki\
 , Greece.\n\n\n\nAbstract\n\nThis talk covers two topics in structural eng
 ineering: earthquake resilience and heritage structures preservation. Desp
 ite notable progress in earthquake engineering\, significant damage or eve
 n collapse is still seen\, especially in long-duration seismic events\, as
  current codes do not account for strong motion duration. The first part o
 f the talk addresses this gap by examining the impact of earthquake durati
 on on the collapse of steel buildings. Through incremental dynamic analyse
 s\, it is shown that longer earthquakes reduce the collapse resistance by 
 up to 60%\, and predictive models for the collapse capacity are developed 
 with due account of duration. Examples of their application and simple pro
 cedures for their integration into seismic codes are also presented. The s
 econd part focuses on strengthening heritage masonry using textile-reinfor
 ced mortar (TRM) systems. The effectiveness of TRM in this context is not 
 fully understood\, and existing models are often based on limited datasets
 . This talk presents an experimental and analytical study of TRM-strengthe
 ned masonry representative of heritage structures in Historic Cairo. Using
  digital image correlation\, the contribution of TRM is quantified\, and a
 nalytical models are developed\, which can reliably predict the performanc
 e of TRM-strengthened heritage masonry\, supporting its long-term preserva
 tion.
