Influence of boundary conditions and size effect on the drift capacity of URM walls

Katrin Beyer, Sarah Petry

In codes the drift capacity of unreinforced masonry (URM) walls is often estimated as a function of the failure mode and the aspect ratio. The empirical relationships are based on results from quasi-static cyclic tests on single URM walls, which were teste ...

Scaling unreinforced masonry for reduced-scale seismic testing

Katrin Beyer, Sarah Petry

When testing multi-storey structures, most testing facilities require the testing of a reduced-scale model. A literature review on tests of scaled masonry structural components revealed that scaling of masonry was rather challenging and often significant d ...

Effective stiffness of reinforced concrete coupling beams

Katrin Beyer, Bing Li

Reinforced concrete (RC) structural walls with coupling beams are widely used as the primary lateral-load-bearing elements in high-rise building structures. Many researches have shown that there is uncertainty in the estimation of the effective stiffness o ...

Adequabilidade de deformações locais como parâmetro na avaliação sísmica de paredes de betão armado

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

O dano severo e o colapso de diversos edifícios com paredes estruturais em betão armado (BA) durante os recentes sismos do Chile (2010) e Nova Zelândia (2011) revelaram que muitas paredes de BA não tiveram o desempenho que seria expectável da aplicação das ...

Modelling shear–flexure interaction in equivalent frame models of slender reinforced concrete walls

Katrin Beyer, Panagiotis Mergos

Quasi-static cyclic tests on reinforced concrete (RC) walls have shown that shear deformations can constitute a significant ratio of the total deformations when the wall is loaded beyond the elastic regime. For slender RC walls that form a stable flexural ...

Quasi-static cyclic tests of two mixed reinforced concrete–unreinforced masonry wall structures

Katrin Beyer, Alessandro Paparo

In several seismic countries, residential buildings are constructed using both reinforced concrete (RC) and unreinforced masonry (URM) walls. Despite their popularity, there is a general lack of knowledge concerning the seismic behaviour of such mixed syst ...

Seismic shear distribution among interconnected cantilever walls of different lengths

Katrin Beyer, Raluca-Tereza Constantin, Sabrina Simonini

Mid- to high-rise buildings in seismic areas are often braced by slender reinforced concrete (RC) walls, which are interconnected by RC floor diaphragms. In design it is typically assumed that the lateral forces are distributed in proportion to the wall’s ...

Observations on out-of-plane behaviour of URM walls in buildings with RC slabs

Katrin Beyer, Marco Tondelli

In Switzerland many new residential buildings are constructed as unreinforced masonry (URM) structures or as mixed structures where URM walls are coupled with reinforced concrete (RC) walls by RC slabs. At present the boundary conditions of URM walls subje ...

Capacity Design of Coupled RC Walls

Katrin Beyer

Capacity design is an important tool that enables controlled ductile response of structures when subjected to earthquakes. The need for specific capacity design requirements for walls coupled by deep coupling beams, however, is often overlooked and it is a ...

New experimental findings on the stability of thin reinforced concrete walls

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) walls may not achieve the expected ductile response and these walls could possibly fail due to global and local bu ...

Numerical study on the force-deformation behaviour of masonry spandrels with arches

Katrin Beyer, Sujith Mangalathu Sivasubramanian Pillai

This paper presents a numerical study on the force-deformation behaviour of masonry spandrels supported on arches which are analysed using simplified micro models. The model is validated against results from quasi-static cyclic tests on masonry spandrels. ...

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 ...

Performance limits of brick masonry spandrels

Katrin Beyer

Spandrel elements in unreinforced brick masonry buildings with timber floors consist of a masonry spandrel supported by either a timber lintel or a masonry arch. When subjected to seismic loading, the force-deformation relationship of such spandrel element ...

Rütteltischversuche an einem Gebäude mit Mauerwerks- und Stahlbetonwänden (Shake table tests on a building with masonry and reinforced concrete walls)

Katrin Beyer, Sarah Petry, Marco Tondelli

Im Rahmen eines europäischen Forschungsprojektes unter Federführung der École Polytechnique Fédérale de Lausanne (EPFL) wurde ein vierstöckiges Gebäude mit Mauerwerks-und Stahlbetonwänden auf dem Rütteltisch des TREES-Labors am EUCENTRE in Pavia (Italien) ...

Review of strength models for masonry spandrels

Katrin Beyer, Sujith Mangalathu Sivasubramanian Pillai

Many older unreinforced masonry (URM) buildings feature timber floors and solid brick masonry. Simple equivalent frame models can help predicting the expected failure mechanism and estimating the strength of a URM wall. When modelling a URM wall with an eq ...

Quasi-static cyclic tests on masonry spandrels

Alessandro Dazio, Katrin Beyer

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 ...
