Esposito, R. (author), Messali, F. (author), Ravenshorst, G.J.P. (author), Schipper, H.R. (author), Rots, J.G. (author)The exploitation of geo-resources in the northern part of the Netherlands (Groningen region) is triggering shallow earthquakes, rising the need of assessing the current building stock. Being the region not prone to tectonic earthquakes, buildings are designed as wind-resistant systems and have specific characteristics that can limit their...journal article 2019

Messali, F. (author), Esposito, R. (author), Jafari, S. (author), Ravenshorst, G.J.P. (author), Korswagen, Paul A. (author), Rots, J.G. (author)In recent years, induced seismicity in the north of the Netherlands significantly increased. As a consequence, the seismic assessment of the built environment, which mainly consists of unreinforced masonry (URM) structures not designed for seismic loads, became of high relevance. Within this context, an extensive multiscale testing program has...conference paper 2018

van de Kuilen, J.W.G. (author), Ravenshorst, G.J.P. (author)There are more than 1000 wood species worldwide available that have the potential to be used in structural applications. Many of these species are tropical hardwood species. In this paper, the mechanical and physical properties of a large number of tropical hardwoods are presented. They are investigated for relationships that are valid for all...conference paper 2018

Esposito, R. (author), Jafari, S. (author), Ravenshorst, G.J.P. (author), Schipper, H.R. (author), Rots, J.G. (author)In recent years induced seismicity in the Netherlands considerably increased. This phenomenon has a wide impact on the built environment, which is mainly composed by unreinforced masonry (URM) structures. These buildings were not designed for seismic loading, and present peculiar characteristics include very slender walls (100 mm thickness and 2...conference paper 2018

Ravenshorst, G.J.P. (author), Mirra, M. (author)The in-plane strength and stiffness as well as the hysteretic behaviour of timber diaphragms is investigated by performing quasi-static cyclic tests. In this report the behaviour of traditional timber floors and roof configurations was studied representing a typical detached masonry house. The configurations are based on a case study from a...report 2017

Messali, F. (author), Ravenshorst, G.J.P. (author), Esposito, R. (author), Rots, J.G. (author)The evaluation of the seismic response of unreinforced masonry buildings is a popular topic all over the world. In recent years, also the Netherlands started to face seismic risk, since the induced seismicity in the north of the country considerably increased (the gas extraction started in 1963, and earthquakes have occurred since the early ‘90s...conference paper 2017

Cyclic pushover test on an unreinforced masonry structure reseambling a typical Dutch terraced houseEsposito, R. (author), Terwel, K.C. (author), Ravenshorst, G.J.P. (author), Schipper, H.R. (author), Messali, F. (author), Rots, J.G. (author)During the last years, induced seismicity in the northern part of the Netherlands increased and the seismic assessment of unreinforced masonry (URM) structures became an important issue. As the problem is recent, the current building stock is not designed to withstand earthquakes and national guidelines are under development, but currently not...conference paper 2017

Ravenshorst, G.J.P. (author), van de Kuilen, J.W.G. (author)The current methods for the determination of the strength properties for wood species for grading purposes require extensive testing. Species independent grading might be a solution for this problem, in particular for tropical hardwoods. The strength reducing characteristics such as knots and slope of grain...conference paper 2016

(author)The current shear strength values for high density tropical hardwoods are very low compared to the values for softwoods, according to European strength class tables. The reason for this is that standardized tests according to European standard EN 408 have not been performed yet for tropical hardwoods. In this...conference paper 2016
