(author), van Dijk, Chris (author), Esposito, Marco (author)LOUPE, the Lunar Observatory for Unresolved Polarimetry of the Earth, is a small, robust spectro-polarimeter for observing the Earth as an exoplanet. Detecting Earth-like planets in stellar habitable zones is one of the key challenges of modern exoplanetary science. Characterizing such planets and searching for traces of life requires the...journal article 2021

Lubelli, B. (author), Moerman, J. (author), Esposito, R. (author), Mulder, K.B. (author)The effect of mortar and brick properties on the growth of ivy-leaved toadflax (Cymbalaria muralis) and yellow corydalis (Pseudofumaria lutea) has been investigated in laboratory. Different mortar compositions were designed and tested in combination with two different bricks. Highly porous bricks and mortars showed good bioreceptivity;...journal article 2021

Chang, L. (author), Rots, J.G. (author), Esposito, R. (author)Out-of-plane (OOP) failure of unreinforced masonry (URM) walls in two-way bending was widely observed after natural hazards such as earthquakes. Of various crucial factors influencing the force capacity of URM walls in OOP two-way bending (force capacity being defined as the wall peak force in terms of pressure), the pre-compression 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

Esposito, R. (author), Ravenshorst, G.J.P. (author), Rots, J.G. (author)Due to the increase of induced seismic activities in the Groningen area (north part of the Netherlands), the assessment of low-rise residential buildings with slender façade piers became of relevance. In this framework, the in-plane response of slender walls made of calcium silicate (CS) brick and element masonry is investigated in this paper...journal article 2021

Chang, L. (author), Rots, J.G. (author), Esposito, R. (author)Research has shown that lateral boundary conditions can have a large influence on the force capacity of two-way spanning unreinforced masonry (URM) walls subjected to out-of-plane (OOP) loading. Differently than laterally free one-way spanning walls, they show a higher force capacity, which however is underestimated by current analytical...book chapter 2020

Drougkas, A. (author), Licciardello, L. (author), Rots, J.G. (author), Esposito, R. (author)Induced seismicity due to gas extraction in the province of Groningen in the Netherlands has a noticeable impact on building structures. Historic masonry structures in the area, which are non-engineered and lacking empirical design features often present in traditionally seismic regions, are especially vulnerable to dynamic loading. Compounding...conference paper 2020

Drougkas, A. (author), Licciardello, L. (author), Rots, J.G. (author), Esposito, R. (author)The province of Groningen in the Netherlands is experiencing the continuous impact of gas extraction in the form of induced seismicity. Due to the absence of naturally occurring seismicity in the region, the historic building stock of Groningen was constructed without empirical design features typically encountered in naturally seismic...journal article 2020

Jafari, S. (author), Rots, J.G. (author), Esposito, R. (author)In this study, tests on cores and companion tests on triplets are compared with respect to the evaluation of the nonlinear shear-sliding behaviour of masonry, including the determination of post-peak softening response. Due to its slightly-destructive sampling nature and its good agreement with triplet results, the core testing method is...journal article 2020

Messali, F. (author), Esposito, R. (author), Ravenshorst, G.J.P. (author), Rots, J.G. (author)The material and structural performance of calcium silicate (CS) brick masonry has received relatively little attention in the past, although this material is often used for the construction of low-rise buildings in Central and Northern Europe. Upon the occurrence of induced seismicity in the north of the Netherlands, an extensive testing...journal article 2020

Chang, L. (author), Messali, F. (author), Esposito, R. (author)Investigations of post-seismic events show that the collapse of walls in out-of-plane (OOP) two-way bending can be one of the most predominant failure mechanisms for unreinforced masonry (URM) structures. To assess the force capacity of URM walls in OOP two-way bending, various analytical formulations have been developed during past decades....journal article 2020

Jafari, S. (author), Rots, J.G. (author), Esposito, R. (author)This study investigates the applicability of the core testing method to assess the complete nonlinear behavior of masonry in compression. A comparative experimental approach was adopted performing compressive tests on cores and companion wallets. Via a correlation study on seven objects, including literature data, a one-to-one correlation for...journal article 2019

Sánchez-Aparicio, Luis Javier (author), Herrero Huerta, M. (author), Esposito, R. (author), Schipper, H.R. (author), González-Aguilera, Diego (author)This paper proposes a photogrammetric procedure able to determine out-of-plane movements experienced by a masonry structure subjected to a quasi-static cyclic test. The method tracks the movement of circular targets by means of a coarse-to-fine strategy. These targets were captured by means of a photogrammetric network, made up of four...journal article 2019

(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

Damiola, M. (author), Esposito, R. (author), Messali, F. (author), Rots, J.G. (author)Out-of-plane failure is one of the most important mechanisms for unreinforced ma-sonry (URM) structures to be prevented in the seismic areas. The one-way out-of-plane bend-ing failure mechanism has been studied by several authors. The two-way bending failure mechanism has received much less attention and only few formulations for specific cases...conference paper 2018

Ferretti, F. (author), Mazzotti, C. (author), Esposito, R. (author), Rots, J.G. (author)Masonry is a composite material, whose behavior is strongly influenced by the presence of vertical and horizontal mortar joints, weak elements along which the shear failure usually occurs. The scope of the present work was to investigate factors that could affect the shear-sliding behavior of masonry, by performing numerical simulations of...conference paper 2018
