Shake-table testing of a stone masonry building aggregate: overview of blind prediction study

City centres of Europe are often composed of unreinforced masonry structural aggregates, whose seismic response is challenging to predict. To advance the state of the art on the seismic response of these aggregates, the Adjacent Interacting Masonry Structu ...

Masonry walls from reclaimed concrete demolition waste

Jakov Oreb, Katrin Beyer, Igor Tomic

The construction sector is the largest consumer of non-renewable resources and the most significant contributor to CO2 emissions. Reusing entire components or reclaiming their constituent parts, instead of recycling structural elements at the material leve ...

Seismic Testing of Adjacent Interacting Masonry Structures – Analysis of a Blind Prediction

Katrin Beyer, Igor Tomic

Masonry aggregates, which emerged as layouts of cities and villages became denser, make up historical centres all over the world. In these aggregates, neighbouring structures may share structural walls that are joined at the interfaces by mortar or interlo ...

Optimal intensity measure and probabilistic seismic demand model for the assessment of historical masonry buildings: application to two case studies

Katrin Beyer, Igor Tomic

This paper presents a probabilistic seismic demand model (PSDM) as a relationship between intensity measures (IMs) and engineering demand parameters (EDPs) for the seismic assessment of two case studies resembling historical masonry buildings. The first on ...

Uncertainties in the Seismic Assessment of Historical Masonry Buildings

Katrin Beyer, Igor Tomic, Francesco Vanin

Seismic assessments of historical masonry buildings are affected by several sources of epistemic uncertainty. These are mainly the material and the modelling parameters and the displacement capacity of the elements. Additional sources of uncertainty lie in ...

Shake-table test on a historical masonry aggregate: prediction and postdiction using an equivalent-frame model

Katrin Beyer, Igor Tomic

Modeling the seismic response of historical masonry buildings is challenging due to many aleatory and epistemic uncertainties. Additionally, the interaction between structural units further complicates predictions of the seismic behavior of unreinforced ma ...

Numerical Simulation of Unreinforced Masonry Buildings with Timber Diaphragms

Katrin Beyer, Igor Tomic, Francesco Vanin, Ivana Bozulic

Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the effect of the connections between floors and walls is rarely discussed or explicitly modelled when simulating the response of such buildings. These flexi ...

Numerical simulations of retrofitting interventions on timber floors in unreinforced masonry

Katrin Beyer, Igor Tomic, Ivana Bozulic

Unreinforced masonry buildings with flexible timber floors are amongst the most vulnerable building typologies for seismic loading. Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the impact of the connect ...

Seismic response of historical masonry buildings and aggregates - large-scale experimental testing and macro-element modelling

Igor Tomic

The seismic analysis of existing unreinforced masonry buildings is a challenging task, troubled by different sources of material and modelling uncertainties. The historical heritage value of a building can further complicate the assessment and design of re ...

Shake table testing of a half-scale stone masonry building aggregate

Katrin Beyer, Igor Tomic

Masonry aggregates have developed throughout city centres of Europe due to a centuries-long densification process that generally lacked consistent planning or engineering. Adjacent units are connected either through interlocking stones or a layer of mortar ...

Lessons learned from a prediction and postdiction of a shake table test on an unreinforced masonry aggregate

Katrin Beyer, Igor Tomic

Historical centers of Europe and Croatia are often formed by unreinforced masonry building aggregates that developed as the layout of the city or village was densified. In these aggregates, adjacent buildings can share structural walls with an older and a ...
