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 ...

Dynamic testing of a four-storey building with reinforced concrete and unreinforced masonry walls: Prediction, test results and data set

Katrin Beyer, Sarah Petry, Marco Tondelli

This paper presents the results of a series of shake-table tests on a half-scale, four-storey building with reinforced concrete (RC) and unreinforced masonry (URM) walls. Due to the lack of reference tests, the seismic behaviour of such mixed structures is ...

Force-displacement response of unreinforced masonry walls for seismic design

Sarah Petry

In regions with low to moderate seismicity, unreinforced masonry (URM) is commonly used for the construction of low to mid-rise buildings. When these structures are subjected to seismic loading, the stiff URM walls attract considerable part of the lateral ...

EPFL2015

Previous test data on unreinforced masonry walls focused on the global response of the wall. A new data set (Petry and Beyer 2014a; D01:10.5281/zenodo.8443) on six wall tests, which is publicly available, allows for linking global to local deformations of ...

Force-displacement response of in-plane loaded URM walls with a dominating flexural mode

Katrin Beyer, Sarah Petry

This article presents a new mechanical model for the non-linear force-displacement response of unreinforced masonry (URM) walls developing a flexural rocking mode including their displacement capacity. The model is based on the plane section hypothesis and ...

Size effects in drift capacities of URM walls

Katrin Beyer, Sarah Petry

Examining the results of a large set of quasi-static cyclic tests on unreinforced masonry (URM) walls showed that the drift capacity of URM walls reduces with increasing wall size. Such a size effect is of concern since most wall tests were carried out on ...

Seismic response of a 4 storey building with reinforced concrete and unreinforced masonry walls

Katrin Beyer, Sarah Petry, Marco Tondelli

In Switzerland many new residential buildings are designed as mixed structures with unreinforced masonry (URM) walls and reinforced concrete (RC) walls while existing URM structures are often retrofitted by replacing selected URM walls by RC walls. The lat ...

Flexural deformations of URM piers: Comparison of analytical models with experiments

Katrin Beyer, Sarah Petry

Despite the fact that displacement-based methods are now frequently applied when assessing the seismic performance of unreinforced masonry (URM) structures, the displacement capacity of in-plane loaded URM piers is still estimated from empirical rather tha ...

Towards displacement-based seismic design of modern unreinforced masonry structures

Katrin Beyer, Sarah Petry, Alessandro Paparo, Marco Tondelli

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 partic ...

Investigating the in-plane mechanical behavior of URM piers via DSFM

Katrin Beyer, Shenghan Zhang, Sarah Petry

In this paper we use the novel Disturbed Stress Field Model (DSFM) from Facconi et al. (2013) to model the lateral in-plane behaviour of different unreinforced masonry (URM) walls which we tested at the laboratory of the EPF Lausanne, Switzerland. The mode ...
