Nijland, Timo G. (author), Lubelli, B. (author), van Zundert, Kim (author), van Hunen, Michiel (author)The impregnation of the exterior surface of a masonry wall with a water repellent is a common intervention in (historic) building renovation and maintenance. Such treatments, whilst degrading at the surface with time under influence of ultra violet light, remain effective below the surface several decades after their application. During...journal article 2024

(author), Yang, Y. (author), Verstrynge, E. (author), Aggelis, D. G. (author)Aging infrastructure globally faces degradation, posing risks and requiring substantial repair investment. Strategic maintenance practices are crucial for evaluating structural conditions and ensuring sustainability. The growing demands on modern materials and structures necessitate enhanced health monitoring approaches. Shifting from...journal article 2024

Gaggero, M.B. (author), Korswagen, Paul A. (author), Esposito, R. (author), Rots, J.G. (author)Cracks are one of the most common expressions of damage in masonry structures. Aside from aesthetic issues, they can compromise the overall behaviour of the structure; therefore, they are undesirable and need to be repaired. The repointing technique is traditionally implemented in this context, especially in historical masonry. Nevertheless,...book chapter 2023

Zhou, Y. (author), Sluys, Lambertus J. (author), Esposito, R. (author)Accurate assessment of the overall mechanical behavior of masonry, composed of bricks and mortar joints, remains challenging due to its inhomogeneous and orthotropic nature. In this study, the feasibility of various mean-field homogenization schemes for the three-dimensional orthotropic elastic properties of masonry is comprehensively...journal article 2022

Fusco, Daniela (author), Messali, F. (author), Rots, J.G. (author), Addessi, Daniela (author), Pampanin, Stefano (author)In recent years, the seismic risk in the north of the Netherlands has increased due to gas extraction. Since 2014, the Delft University of Technology started a research program to assess the seismic response of unreinforced masonry (URM) buildings. The Dutch URM buildings are characterized by slender piers and transverse walls. In common...conference paper 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

Longo, M. (author), Sousamli, M. (author), Korswagen, Paul A. (author), van Staalduinen, P.C. (author), Rots, J.G. (author)Recent, light earthquakes induced by the extraction of gas in the north of the Netherlands have been linked to light, mostly aesthetic damage of the traditional masonry structures in the region; this is also connected to economic losses and societal unrest. To be able to accurately assess the light damage, detailed finite element models are...journal article 2021

Korswagen, Paul A. (author), Rots, J.G. (author)Recent, induced earthquakes in the north of the Netherlands have led to a large number of damage claims. Many claims can be considered to fall into the category of ‘light damage’ to the ubiquitous, unreinforced masonry structures in the region. To evaluate and predict the behaviour of cracks, characteristic of light masonry damage, caused by...conference paper 2021

Xie, Z. (author), Sousamli, M. (author), Messali, F. (author), Rots, J.G. (author)This paper proposes a sub-step based iterative constitutive model for line interface elements used to analyse masonry structures loaded in-plane. Based on a total deformation theory, the model adopts characteristics of multi-surface plasticity, including a Coulomb friction failure surface for shear, with tension and compression cut-off and...journal article 2021

Drougkas, A. (author), Esposito, R. (author), Messali, F. (author), Sarhosis, Vasilis (author)Masonry panels consisting of piers and spandrels in buildings are vulnerable to in-plane actions caused by seismicity and soil subsidence. Tectonic seismicity is a safety hazard for masonry structures, whereas low-magnitude induced seismicity can be detrimental to their durability due to the accumulation of light damage. This is particularly...journal article 2021

Jansen, L. (author), Korswagen, Paul A. (author), Bricker, J.D. (author), Pasterkamp, S. (author), de Bruijn, K.M. (author), Jonkman, Sebastiaan N. (author)Failure of residential buildings during floods is an important cause of damage and loss of life. In the case of the Netherlands, the collapse of buildings is implicitly included in current damage and mortality curves since these are generated from historical data. However, the Netherlands has not experienced destructive flooding since 1953, so...journal article 2020

Yu, C. (author)It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...doctoral thesis 2019

Korswagen, Paul A. (author), Jonkman, Sebastiaan N. (author), Terwel, K.C. (author)Evaluating and predicting structural damage from multi-hazards is a complex task mainly due to the varying ways in which hazards affect structures. Also, different damage scales that employ different parameters and criteria are used for evaluating the hazards, making a connection between the damage assessment of two or more hazards difficult....journal article 2019

Maljaee, Hamid (author), Ghiassi, B. (author), Lourenço, Paulo B. (author)Near Surface Mounted (NSM) reinforcement is an interesting technique for seismic strengthening of masonry and historical structures. Despite having several advantages compared to conventional techniques, little attention has been given to understanding the involved mechanisms (such as bond behavior) in the performance of masonry components...journal article 2018

Panagoulias, S. (author), Laera, Anita (author), Vilhar, Gregor (author), Brinkgreve, R.B.J. (author)In this paper, a constitutive model for masonry structures is presented. It is based on the Jointed Rock (JR) model with overall Mohr-Coulomb (MC) failure criterion, and it is implemented as a user-defined soil model in the finite element<br/>code PLAXIS. The Masonry model is a linear elastic-perfectly plastic model capable of simulating the...conference paper 2018

Yu, C. (author), Hoogenboom, P.C.J. (author), Rots, J.G. (author)Quasi brittle materials, such as un-reinforced masonry or concrete are difficult to analyse because often the traditional Newton–Raphson (N-R) procedure fails to converge. Many solutions have been proposed such as Sequentially Linear Analysis (SLA), but these may fail in case of non-proportional loading with a large prestress. In this paper a...journal article 2018
