DESCRIPTION:Hervé Degée is Professor at Hasselt University (Belgium) an
 d guest-professor at the Universities of Ghent and Liege. Head of the stru
 ctural testing lab. In the last years\, mainly active in research on Hybri
 d and Composite steel structures and on Masonry structures\, with a strong
  focus on seismic design aspects. Member of a number of Eurocode committee
 s at European level and Chair of the Belgian mirror groups for Eurocode 3/
 4 and 8.\nThis talk presents two recent research projects exploring how bo
 th innovative structural solutions and non-structural design choices influ
 ence the seismic behaviour of buildings. The first part focuses on load-be
 aring perforated clay masonry walls\, commonly used in residential buildin
 gs due to their efficiency and low weight\, but often equipped with acoust
 ic isolation layers (rubber interlayers) to improve sound insulation. Alth
 ough not intended for seismic purposes\, these flexible layers significant
 ly modify the stiffness and dynamic response of the walls\, potentially ac
 ting as partial seismic isolation and shifting failure mechanisms from bri
 ttle shear to rocking. Results from recent cyclic experimental tests will 
 be presented to illustrate these effects. The second part introduces an in
 novative hybrid coupled shear wall system developed within the European HY
 CAD project. The system combines a reinforced concrete wall with external 
 steel columns connected through replaceable steel coupling links\, allowin
 g forces and deformations to be redistributed efficiently during earthquak
 es. Experimental results at different scales show that this solution provi
 des high lateral stiffness under low-intensity earthquakes and controlled 
 ductile behaviour under stronger events\, with damage concentrated in repa
 irable steel components. Together\, these studies contribute to more resil
 ient and repairable seismic design strategies.\n
