Pareto-like sequential sampling heuristic for global optimisation

In this paper, we propose a simple global optimisation algorithm inspired by Pareto’s principle. This algorithm samples most of its solutions within prominent search domains and is equipped with a self-adaptive mechanism to control the dynamic tightening o ...

RC U-shaped walls subjected to in-plane, diagonal, and torsional loading: New experimental findings

Katrin Beyer, Ryan Hoult

Although reinforced concrete U-shaped walls are popular in construction practice internationally, there is a paucity of experimental research investigating the seismic performance of such salient elements. The present paper summarizes an experimental campa ...

Seismic testing of adjacent interacting masonry structures

Katrin Beyer, Andrea Penna, Igor Tomic

In many historical centres in Europe, stone masonry buildings are part of building aggregates, which developed when the layout of the city or village was densified. In these aggregates, adjacent buildings share structural walls to support floors and roofs. ...

Investigating the cracking of plastered stone masonry walls under shear–compression loading

Katrin Beyer, Amir Rezaie, Michele Godio

Cracks are the most important source of information about the damage that occurs to unreinforced masonry piers under seismic actions. To predict the structural state of unreinforced masonry piers after an earthquake, research models have been developed to ...

Numerical Simulation of Unreinforced Masonry Buildings with Timber Diaphragms

Katrin Beyer, Francesco Vanin, Igor Tomic, 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 ...

Spherical cap harmonic analysis (SCHA) for characterising the morphology of rough surface patches

Katrin Beyer, Mahmoud S. M. Shaqfa

We use spherical cap harmonic (SCH) basis functions to analyse and reconstruct the morphology of scanned genus-0 rough surface patches with open edges. We first develop a novel one-to-one conformal mapping algorithm with minimal area distortion for paramet ...

Überprüfung bezüglich Erdbeben von Holzbalkendecken in Bestandesbauten

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

Viele bestehende Mauerwerksgebäude in der Schweiz weisen Holzbalkendecken als Deckenkonstruktion auf. Dies triff vor allem für Gebäude zu, die bis in die erste Hälfte des 20. Jahrhundert erbaut wurden. Holzbalkendecken sind in ihrer Ebene sehr flexibel und ...

Equivalent-Frame Modeling of Two Shaking Table Tests of Masonry Buildings Accounting for Their Out-Of-Plane Response

Katrin Beyer, Francesco Vanin, Andrea Penna

Equivalent frame models are an effective tool for the seismic assessment of existing masonry structures. Due to their simplicity, these models can be used to perform multiple nonlinear dynamic analyses, accounting explicitly for different sources of modeli ...

Shake table test of a masonry building retrofitted with shotcrete

Katrin Beyer, Kiarash Mohtasham Dolatshahi

This paper presents the results of a series of shake table tests carried out on a half-scale single-story unreinforced masonry building with asymmetric openings. First, the unretrofitted building is subjected to seven increasing steps of bidirectional seis ...

A three-dimensional macroelement for modelling the in-plane and out-of-plane response of masonry walls

Katrin Beyer, Francesco Vanin, Andrea Penna

The seismic performance of unreinforced masonry buildings is commonly assessed using equivalent frame modelling. Its computational efficiency allows for a large number of analyses to be conducted, which are often required to account for epistemic and aleat ...

Sensitivity analysis of fractal dimensions of crack maps on concrete and masonry walls

Katrin Beyer, Amir Rezaie

Assessing building damage after earthquakes requires a visual inspection of the damage, indicated by maps of the cracking pattern on walls, which could be standardized via automated algorithms. To quantitate this damage, fractal dimensions of these crack m ...

Blind predictions of shake table testing of aggregate masonry buildings

Katrin Beyer, Andrea Penna, Igor Tomic

In many historical centers in Europe, stone masonry is part of building aggregates, which developed when the layout of the city or village was densified. The analysis of such building aggregates is very challenging and modelling guidelines missing. Advance ...

The ratio of shear to elastic modulus of in-plane loaded masonry

Katrin Beyer, Bastian Valentin Wilding, Michele Godio

When designing unreinforced masonry buildings, the wall stiffness and, consequently, the masonry elastic and shear modulus E and G are essential parameters. Current codes provide empirical estimates of the masonry elastic modulus and a ratio between the sh ...

Shake table testing of aggregate masonry buildings

Katrin Beyer, Andrea Penna, Igor Tomic

Masonry building aggregates can be found throughout historical city centers of Europe. Adjacent buildings have often developed during the long densification process, without consistent planning or engineering. It is common for neighboring units to share a ...

Characterization of mortar-timber and timber-timber cyclic friction in timber floor connections of masonry buildings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

The seismic performance of buildings depends critically on the stiffness and strength of storey diaphragms. Whilst for modern reinforced concrete or steel structures the connection between floors and lateral resisting members is often assumed as monolithic ...

Experimental investigation of strength, stiffness and drift capacity of rubble stone masonry walls

Katrin Beyer, Amir Rezaie, Michele Godio

There is limited available research on rubble stone masonry walls, which are vulnerable under seismic loading. This paper presents an experimental campaign of cyclic shear compression tests on six large-scale walls of this topology. The effect of the axial ...

Extended Tension Chord Model for Boundary Elements of RC Walls Accounting for Anchorage Slip and Lap Splices Presence

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

This paper presents a mechanical model for the simulation of reinforced concrete (RC) wall boundary elements with lap splices, which builds on the tension chord model. The model is composed of an assembly of components, each one accounting for a different ...

Decay of Torsional Stiffness in RC U-Shaped Walls

Katrin Beyer, Ryan Hoult

Reinforced concrete (RC) U-shaped walls are a popular construction choice, commonly used to resist the lateral loads from wind and earthquakes. In many buildings, the center of stiffness of a floor is eccentric from the center of mass and the building will ...
