Arslan, O. (author)Post-earthquake structural damage shows that out-of-plane wall collapse is one of the most prevalent failure mechanisms in unreinforced masonry (URM) buildings. This issue is particularly critical in Groningen, a province located in the northern part of the Netherlands, where low-intensity ground shaking has occurred since 1991 due to gas...doctoral thesis 2023

Mirra, M. (author), Ravenshorst, G.J.P. (author), de Vries, P.A. (author), van de Kuilen, J.W.G. (author)Timber diaphragms in existing buildings are often too flexible in their plane, and can thus potentially cause out-of-plane collapses of walls during earthquakes. A very efficient retrofitting method to increase their in-plane stiffness and energy dissipation is the overlay of plywood panels. However, the usual characterization of the floors by...journal article 2021

Mirra, M. (author), Sousamli, M. (author), Longo, M. (author), Ravenshorst, G.J.P. (author)In the region of Groningen (NL), human-induced earthquakes initiated by gas extraction are causing structural damage. In that area, the building stock is mainly composed of unrein- forced masonry (URM) buildings with light and flexible timber floors and roofs. Thus, an ex- perimental campaign was arranged for assessing the in-plane response of...conference paper 2021

Mirra, M. (author), Ravenshorst, G.J.P. (author), van de Kuilen, J.W.G. (author)Traditional timber floors cannot normally withstand horizontal seismic loads without large deformations. This may lead to a corresponding out-of-plane collapse of masonry walls in existing buildings. This situation is even more critical in the Netherlands, around the city of Groningen, where human-induced earthquakes started to take place....journal article 2020
