Quasi-static monotonic and cyclic tests on composite spandrels
Katrin Beyer, Alessandro Dazio
In modern unreinforced masonry (URM) walls, the vertical piers are connected at the storey levels by reinforced concrete (RC) ring beams or RC slabs. Particularly, in the outer walls, the spandrel element also includes a masonry spandrel on top of the RC b ...
Earthquake Engineering Research Inst2012Quasi-static cyclic tests on masonry spandrels
Katrin Beyer, Alessandro Dazio
This paper presents the results of an experimental campaign on masonry spandrels. Within this campaign four masonry spandrels were subjected to quasi-static cyclic loading. Two different spandrel configurations were tested. The first configuration comprise ...
Earthquake Engineering Research Inst2012Modelling of spandrel elements in URM structures with RC slabs or ring beams
Katrin Beyer, Alessandro Dazio
In many unreinforced masonry (URM) buildings reinforced concrete (RC) slabs or ring beams maintain the integrity of the building when subjected to seismic loading and redistribute forces between different URM piers. In addition, RC slabs and ring beams con ...
2011Experimental investigation of the effect of the longitudinal reinforcement content of ring beams on the cyclic behavior of masonry spandrels
Katrin Beyer, Alessandro Dazio
In many unreinforced masonry (URM) buildings reinforced concrete (RC) ring beams are introduced at each storey in order to maintain the integrity of the building when subjected to seismic loading. Such ring beams also contribute to the in-plane resistance ...
2011Shear deformations of slender reinforced concrete walls under seismic loading
Katrin Beyer, Alessandro Dazio
Experimental results gained from quasi-static cyclic tests on 34 slender structural reinforced concrete walls available in the literature are used to examine the shear deformations for displacement demands in the inelastic range. Based on these results the ...
American Concrete Institute2011Experimental investigation of the cyclic behaviour of unreinforced masonry spandrels
Katrin Beyer, Alessandro Dazio
In unreinforced masonry (URM) walls the vertical piers are connected by horizontal spandrel elements. Numerical simulations have shown that spandrels influence significantly the global wall behaviour under seismic loading. Despite their importance, experim ...
2010Seismic behaviour of different types of masonry spandrels
Katrin Beyer, Alessandro Dazio
Most residential buildings that were constructed during the last century in Switzerland are 2-6 storey unreinforced masonry (URM) structures. At the beginning of the century, houses were constructed with timber floors and small bricks. This type of constru ...
2010Quasi-static cyclic tests of two prefabricated, reinforced masonry walls
Katrin Beyer, Michael Markus Rupf, Alessandro Dazio
In the second half of the 20th century, the majority of residential buildings in Switzerland have been built with unreinforced brick masonry walls and reinforced concrete floors. Following a re-evaluation of the seismic hazard in Switzerland, a country of ...
2010Quasi-static cyclic tests and plastic hinge analysis of RC structural walls
Katrin Beyer, Alessandro Dazio
This paper presents the results of quasi-static cyclic tests on six reinforced concrete (RC) walls performed at the ETH Zurich. These large-scale tests investigate the effect of different vertical reinforcement contents and different reinforcement ductilit ...
Elsevier2009Upper bound limit analysis of meso-mechanical spandrel models for the pushover analysis of 2D masonry frames
Katrin Beyer, Alessandro Dazio
In this paper, a numerical model for the pushover analysis of in-plane loaded unreinforced masonry walls is presented. For the analysis of the walls, which consist of vertical piers connected by horizontal masonry spandrels, an equivalent frame model is ad ...
