Experimental Investigation on Size-Effect of Rubble Stone Masonry Walls Under In-Plane Horizontal Loading: Overview and Preliminary Results

Rubble stone masonry is a common construction typology of historical city centres and vernacular architecture. While past earthquakes have shown that it is one of the most vulnerable masonry construction typologies, there are few experimental campaigns giv ...

Applying a 2D Variational Rigid Block Modeling Method to Rubble Stone Masonry Walls Considering Uncertainty in Material Properties

Katrin Beyer, Qianqing Wang, Mathias Christian Haindl Carvallo

The computational cost of detailed micro-modeling of masonry structures can be minimized with rigid block analysis methods, where a variational formulation is particularly interesting as it allows for nonlinear pushover analysis. This work investigates the ...

Digital Twins of Stone Masonry Buildings for Damage Assessment

Radhakrishna Achanta, Katrin Beyer, Bryan German Pantoja Rosero

Digital twins are virtual models of physical objects or systems that enable real-time monitoring and analysis. In the ﬁeld of stone masonry buildings, digital twins can be used to assess damage, predict maintenance needs, and opti- mize building performanc ...

A database of shake-table tests conducted on unreinforced masonry buildings

Katrin Beyer, Mathias Christian Haindl Carvallo

Experimental results obtained from shake-table tests on complete unreinforced masonry buildings (URM) play a crucial role in enhancing modeling techniques and reducing uncertainties in seismic assessments for this type of building. This paper presents an o ...

Masonry walls from reclaimed concrete demolition waste

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 ...

Collapse fragility analysis of historical masonry buildings considering in-plane and out-of-plane response of masonry walls

Katrin Beyer, Igor Tomic

This paper explores the seismic fragility assessment of historical masonry buildings in the context of performance-based earthquake engineering, using multiple-record incremental dynamic analyses (MR-IDA). The methodology is applied to two case studies, th ...

Rising from rubble - Leveraging existing construction tools for upcycling concrete waste into slender walls

Katrin Beyer, Maxence Grangeot, Corentin Jean Dominique Fivet, Qianqing Wang, Stefana Parascho

In this paper, we present a new method for upcycling concrete rubble waste into slender walls through the lightweight digital augmentation of mainstream construction machines. By using such method, the environmental impact of concrete construction and demo ...

Structural Concrete Rubble Arrangements - A Framework for Upcycling Demolition Waste into Slender Masonry Walls for Buildings

Katrin Beyer, Maxence Grangeot, Corentin Jean Dominique Fivet, Qianqing Wang, Stefana Parascho

Reused concrete rubble is a challenging material to design and construct with despite its potential for diverging waste from landfilling and energyintensive recycling. We propose a design to construction framework that leverages a camera and computationall ...

UNCERTAINTY QUANTIFICATION IN THE CONSTITUTIVE BEHAVIOR OF HDRBs

Katrin Beyer

High Damping Rubber Bearings (HDRBs) are widely used in seismic isolation of structures, and their force-deformation constitutive behavior controls the lateral structural response during an earthquake. However, given the many components and steps involved ...

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 ...

Seismic Testing of Adjacent Interacting Masonry Structures

Katrin Beyer, Andrea Penna, Igor Tomic

Masonry buildings form building aggregates around the world in historical centers, which developed as the layout of the city or village densified. In these aggregates, adjacent buildings can share structural walls, connected at the interfaces by interlocki ...

Damage-augmented digital twins towards the automated inspection of buildings

Radhakrishna Achanta, Katrin Beyer, Bryan German Pantoja Rosero

Current procedures for the rapid inspection of buildings and infrastructure are subjective, time-consuming, and cumbersome to document, necessitating new technologies to automate the process and eliminate these shortcomings. Fortunately, recent development ...

Experimental investigation of the behaviour of injection anchors in rubble stone masonry

Katrin Beyer

The seismic response of historical masonry buildings is largely controlled by the effectiveness of wall-todiaphragm connections, which can be improved using injection anchors. Despite their use, there is a need for a better understanding of the performance ...

Towards real-time digital twins for post-earthquake damage assessment of masonry buildings

Radhakrishna Achanta, Katrin Beyer, Bryan German Pantoja Rosero

Currently, post-earthquake assessment is performed visually, which implies that inspectors visit the damaged buildings and, based on their expertise, assign a damage grade. Yet, visual inspection is subjective, time-consuming and difficult to document. In ...

Geometrical digital twins of the as-built microstructure of three-leaf stone masonry walls with laser scanning

Yves Weinand, Katrin Beyer, Julien Gamerro, Andrea Settimi, Savvas Saloustros, Andrea Cabriada Ascencio

Research on irregular stone masonry walls is hampered by the lack of detailed geometrical models of their internal micro-structure, i.e. the shape and size of each stone and its position within the wall. Without such a geometric digital twin of walls teste ...

Automated image-based generation of finite element models for masonry buildings

Radhakrishna Achanta, Katrin Beyer, Bryan German Pantoja Rosero

To predict the response of masonry buildings to various types of loads, engineers use finite element models, specifically solid-element and macro-element models. For predicting masonry responses to seismic events in particular, equivalent frame models-a su ...
