Defining a braking probability to estimate extreme braking forces on road bridges

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart

A probabilistic approach is necessary to estimate the magnitude of the braking force that compares in terms of return period with the vertical traffic loads present in bridge design codes. A data set from a Danish Field Operational Test served as support t ...

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 ...

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

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

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 ...

Modelling of the Cyclic Response of an Unreinforced Masonry Wall through a Force Based Beam Element

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Francesco Vanin

The seismic assessment of existing masonry buildings is based on the prediction of their nonlinear response under lateral loading. This requires a reliable estimation of the force and displacement demand. For this purpose, modelling strategies using struct ...

Reducing uncertainties in response predictions of earthquake-damaged masonry buildings using data from image-based inspection

Ian Smith, Katrin Beyer, Bryan German Pantoja Rosero, Mathias Christian Haindl Carvallo

Image information about the state of a building after an earthquake, which can be collected without endangering the post-earthquake reconnaissance activities, can be used to reduce uncertainties in response predictions for future seismic events. This paper ...

Experimental investigation of the effect of the longitudinal reinforcement content of ring beams on the cyclic behavior of masonry spandrels

Katrin Beyer, Alessandro Dazio

In many unreinforced masonry (URM) buildings reinforced concrete (RC) ring beams are introduced at each storey in order to maintain the integrity of the building when subjected to seismic loading. Such ring beams also contribute to the in-plane resistance ...

Trilinear Model for the Out-of-Plane Seismic Assessment of Vertically Spanning Unreinforced Masonry Walls

Katrin Beyer, Michele Godio

Out-of-plane failure of masonry walls is often responsible for the partial collapse of unreinforced masonry structures. Modeling the out-of-plane response of these walls is therefore key in the assessment of existing buildings. The paper presents a new tri ...

Sensitivity of drift capacities of URM walls to cumulative damage demands and implications on loading protocols for quasi-static cyclic tests

Katrin Beyer, Panagiotis Mergos

Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of q ...

Mechanical Model for flexural behaviour of slab-column connections under seismically induced deformations

Katrin Beyer, Aurelio Muttoni, Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported on columns are one of the most widely used structural systems for office and industrial buildings. In regions of medium to high seismic risk RC walls are typically added as lateral force resisting system and to ...

Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding

Empirical drift capacity models for in-plane loaded unreinforced masonry (URM) walls are derived from results of quasi-static cyclic shear-compression tests. The experimentally determined drift capacities are, however, dependent on the applied demand, i.e. ...

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 ...

Effect of damping models on the simulation of seismic axial forces in a reinforced concrete bridge pier

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

Post-reconnaissance findings after recent earthquakes have shown that the effect of the vertical acceleration component of the ground motion can be more damaging than typically considered thus far, particularly in near-field regions where the ratio of vert ...

Ductility reduction factor formulations for seismic design of RC wall and frame structures

Matteo Zerbin, Katrin Beyer

Seismic design of standard structures is typically founded on a force-based design approach. Over the years this approach has proven robust and easily applicable by design engineers and - in combination with capacity design principles - it provides a good ...

Shear deformations of slender reinforced concrete walls under seismic loading

Katrin Beyer, Alessandro Dazio

Experimental results gained from quasi-static cyclic tests on 34 slender structural reinforced concrete walls available in the literature are used to examine the shear deformations for displacement demands in the inelastic range. Based on these results the ...

Influence of Lap Splices on the Deformation Capacity of RC Walls. II: Shell Element Simulation and Equivalent Uniaxial Model

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

Spliced longitudinal reinforcement may result in a reduction of both strength and displacement capacity of reinforced concrete (RC) members. This applies in particular when lap splices are located in regions where inelastic deformations concentrate, such a ...

Numerical evaluation of test setups for determining the shear strength of masonry

Katrin Beyer, Nicolas Richart, Shenghan Zhang, Lyne Desharnais

The bond shear strength between masonry units and mortar is the weakest link in a masonry wall. Different material tests have been developed in order to characterize this bond behaviour. The objective of this study is to evaluate three common test setups t ...

Response of thin lightly-reinforced concrete walls under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

During the last two decades, thin concrete walls have been frequently used to brace mid- to high-rise buildings in some Latin American countries. This structural system differs significantly in terms of wall geometry and reinforcement layout from tradition ...

Peak and residual strengths of brick masonry spandrels

Katrin Beyer

Unreinforced masonry (URM) walls comprise vertical piers and horizontal spandrels, which together form the lateral load resisting system. Whereas past research yielded significant advances in the understanding of the force-deformation characteristics of 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 ...

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 ...
