Derivation of the properties of masonry through micro-modeling techniques
(Universitat Politècnica de Catalunya, 2015-04-20)
Doctoral thesis
Open AccessThe aim of this thesis is to present a framework for the application of micro-modeling techniques for the analysis of unreinforced masonry structures. Finite element analyses of case studies from the literature are carried ... -
Electromechanical testing of smart lime mortars for structural health monitoring
(2022)
Conference report
Open AccessMasonry structures are characterised by low tensile strength and limited ductility. Excessive static or high-cyclic loading or seismic excitation can lead to large localised strains and cracking. It is therefore essential ... -
Experimental analysis and detailed micro-modeling of masonry walls subjected to in-plane shear
(Elsevier, 2019-01)
Article
Open AccessA detailed experimental campaign is presented dealing with masonry walls subjected to shear. The masonry walls are modeled using detailed micro-modeling techniques. Good agreement is found between the experimental and ... -
Experimental and numerical study of historic masonry with bed joint reinforced repointing
Conference report
Open AccessInduced seismicity due to gas extraction in the province of Groningen in the Nether- lands has a noticeable impact on building structures. Historic masonry structures in the area, which are non-engineered and lacking ... -
Homogenisation of masonry structures subjected to seismic loads through matrix/inclusion micromechanics
(Elsevier, 2022-04)
Article
Open AccessThe mechanical properties of masonry, both in the linear elastic range and after the onset of damage, are dependent on the geometric and mechanical properties of its constituent materials: the units and the mortar. Finite ... -
In-plane behaviour of rammed earth under cyclic loading: Experimental testing and finite element modelling
(2016-10)
Article
Open AccessThe intent of this paper is to numerically simulate the in-plane behaviour of rammed earth walls under cyclic shear-compression tests. The experimental testing allowed obtaining the maximum horizontal loads, the displacement ... -
In-plane seismic behaviour of retrofitted masonry walls subjected to subsidence-induced damage
(2020-11)
Article
Open AccessThe 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 ... -
