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

Katrin Beyer, Yves Weinand, Julien Gamerro, Savvas Saloustros, Andrea Settimi, 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 ...

Deep Q-learning agent for building earthquake resisting wall

Katrin Beyer, Qianqing Wang, Ketson Roberto Maximiano Dos Santos

The construction of dry-joint brick masonry that is subject to seismic loading can be modelled as a strategy problem wherein bricks must be laid to form a load resisting structure. To learn how to mount bricks while considering relevant engineering criteri ...

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 ...

Shear to elastic modulus ratio in unreinforced masonry

Katrin Beyer, Bastian Valentin Wilding, Michele Godio

In the seismic design of unreinforced masonry walls, the elastic modulus E and shear modulus G are essential parameters for the calculation of the in-plane wall stiffness. Current codes provide empirical estimates of the elastic modulus and furthermore a r ...

Micro-mechanical finite element modeling for in-plane behavior of historical masonry

Shenghan Zhang

Seismic assessment of unreinforced masonry structures remains a challenge. This dissertation investigates the in-plane behavior of historical masonry elements and proposes an advanced simulation method based on the cohesive zone model (CZM) in a finite ele ...

Influence of boundary conditions on the out-of-plane response of brick masonry walls in buildings with RC slabs

Katrin Beyer, Marco Tondelli

In modern unreinforced masonry buildings with stiff RC slabs, walls of the top ﬂoor are most susceptible to out-of-plane failure. The out-of-plane response depends not only on the acceleration demand and wall geom-etry but also on the static and kinematic ...

Effect of static and kinematic boundary conditions on the out-of-plane response of brick masonry walls

Katrin Beyer

The Unreinforced Wall (URM) elements that are most susceptible to out-of-plane failure are wall elements of the upper storeys where the accelerations are largest. In modern URM buildings with reinforced concrete slabs, the out-of-plane mechanism involves t ...

In-plane cyclic behaviour of unfired clay and earth brick walls in both unstrengthened and strengthened conditions

Angelo Garofano

This article presents the outcome of a series of in-plane shear tests on non-traditional masonry walls under unstrengthened and strengthened conditions. The uniqueness of the experiments arises from the testing of unfired clay and earth (adobe) bricks, whi ...

Review of strength models for masonry spandrels

Katrin Beyer, Sujith Mangalathu Sivasubramanian Pillai

Many older unreinforced masonry (URM) buildings feature timber floors and solid brick masonry. Simple equivalent frame models can help predicting the expected failure mechanism and estimating the strength of a URM wall. When modelling a URM wall with an eq ...

A new concept of modular kinematics to design ultra-high precision flexure-based robots

Reymond Clavel, Murielle Richard

This work deals with the kinematic conception and the mechanical design of ultra-high precision robots, which are at present costly to develop, both in time and money. The aim of this paper is thus to introduce a new modular concept of kinematics which all ...

Establishing stress-strain relationship for natural-stone masonry

The conservation of historical monuments and especially natural stone masonry arch bridges is an issue which is becoming increasingly important. The prerequisite for any analysis of the load carrying capacity of such stonework is a precise knowledge of its ...
