“…Above all in Switzerland, the consideration of masonry based on stress fields is very common and not at all new. The failure conditions for masonry under biaxial loading developed in 1984 by Ganz [5] laid the foundations for the application of plasticity theory in masonry building. These form the basis for the calculation of the load-bearing capacity of masonry panels under combined loading of axial force and shear in the Swiss standard SIA 266 [6].…”

“…Die bereits 1984 von Ganz [5] entwickelten Bruchbedingungen für Mauerwerk unter zweiachsiger Beanspruchung legten den Grundstein für die Anwendung der Plastizitätstheorie im Mauerwerksbau. Diese bilden die Grundlage zur Berechnung der Tragfähig-keit von Mauerwerksscheiben unter kombinierter Beanspruchung durch Normalkraft und Schub in der Schweizer Norm SIA 266 [6].…”

“…12.2.1), three pairs of tests on URM walls were identified where one wall had been subjected to monotonic loading and the other to cyclic loading. The first two pairs stem from the experimental campaign by Ganz and Thürlimann (1984), the third from Magenes and Calvi (1992). Ganz and Thürlimann applied always 10 cycles per amplitude level, which from today's point of view is certainly not representative since it exceeds considerably the number of cycles imposed by an earthquake.…”

Unreinforced masonry (URM) structures are known to be rather vulnerable to seismic loading. Modern URM buildings with reinforced concrete (RC) slabs might, however, have an acceptable seismic performance for regions of low to moderate seismicity. In particular in countries of moderate seismicity it is often difficult to demonstrate the seismic safety of modern URM buildings by means of force-based design methods. Displacement-based design methods are known to lead to more realistic and less conservative results, opening up hence new opportunities for the use of structural masonry. An effective implementation of displacement-based design approaches requires reliable estimates of the structure's force and displacement capacity. This paper contributes to this endeavour by taking a fresh look at the drift capacity of URM walls with hollow clay bricks and mortar joints of normal thickness. It discusses in particular the influence of the size of the test unit and the applied loading history and loading velocity on the drift capacities of URM walls. IntroductionAlthough unreinforced masonry (URM) construction features excellent properties with regard to sustainability, durability, indoor climate and fire resistance, in most regions of moderate seismicity the total amount of structural masonry in new residential buildings has decreased over the last three decades (Magenes 2006). One reason for this decrease relates to the conservatism of force-based methods which often lead to the situation that URM buildings do not satisfy the seismic

“…This information on the local response shall serve also other researchers as input for the validation of models (numerical or mechanical) not only on the global but also on the local level. In the past, often the tests by Ganz and Thürlimann (1984) were used for validation purposes (e.g. Lourenço 1996;Furtmüller and Adam 2011;Facconi et al 2014).…”

Limit states of modern unreinforced clay brick masonry walls subjected to in-plane loading

Recent research showed that the in-plane horizontal displacement capacity of unreinforced masonry (URM) walls depends on numerous factors that are not yet captured by current empirical drift capacity models; e.g., axial stress, shear span, geometry of the walls and the material used. In order to improve the performance-based assessment of URM wall buildings, future research should aim at developing numerical and mechanical models that link the global force-displacement response of URM walls to local deformation measures such as strains. This paper addresses the behaviour of modern clay brick masonry and makes first contributions to such an endeavour by the evaluation of experimental results: first, two sets of limit states are proposed that link local damage limit states to characteristic points of the global force-displacement response of the URM wall. The two sets define limit states for walls developing a shear or a flexural mechanism respectively. Second, local deformation measures deemed suitable for the characterisation of these limit states are evaluated from optical measurement data of quasi-static cyclic wall tests. These include strains, compression zone depth and the ratio of shear to flexural deformations.
