Modelling the seismic response of modern URM buildings retrofitted by adding RC walls

Modern unreinforced masonry buildings with reinforced concrete slabs are often retrofitted by inserting reinforced concrete walls. The main advantages of this technique are the increase in strength and displacement capacity with respect to masonry structur ...

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 ...

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 ...

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 ...

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 ...

Seismic behaviour of mixed RC-URM wall structures: comparison between numerical results and experimental evidence

Katrin Beyer, Alessandro Paparo

Although mixed reinforced concrete (RC) - unreinforced masonry (URM) wall structures are often used, experimental and numerical studies on their seismic behaviour are scarce. Previous studies pointed out that the obtained results from numerical simulations ...

Influence of coupling on the displacement capacities of URM piers – comparison of experimental results with existing recommendations

Katrin Beyer, Sarah Petry

In existing European recommendations the drift capacity of unreinforced masonry (URM) piers is estimated as a function of the failure mode, aspect ratio and/or axial load ratio. The empirical relationships are based on a set of results from quasi-static cy ...

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 ...

Fragility Analysis of Existing Unreinforced Masonry Buildings through a Numerical-based Methodology

Pierino Lestuzzi, Amin Karbassi

As an approach to the problem of seismic vulnerability evaluation of existing buildings using the predicted vulnerability method, numerical models can be applied to define fragility curves of typical buildings which represent building classes. These curves ...

Quasi-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 ...
