Tri-linear model for the out-of-plane seismic assessment of unreinforced masonry walls

Katrin Beyer, Michele Godio

A new model describing the response of vertically-spanning unreinforced masonry walls subjected to out-of-plane loading is presented. The model approximates the real behaviour of the walls by a tri-linear force-displacement relationship, which is suitable ...

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 ...

A 2D typology generator for historical masonry elements

Katrin Beyer, Shenghan Zhang

The mechanical response of stone masonry depends on the properties of the components and also on the typology created by the stone units and the mortar joints. While the influence of the component strength on masonry is relatively well studied, few studies ...

Simplified micro-modelling of shear-compression stone masonry walls and their interaction with plaster

Katrin Beyer, Bastian Valentin Wilding, Michele Godio

The performance of shear-compression stone masonry walls with regard to their interaction with plaster is investigated by means of numerical simulations. A 3D finite element model based on the simplified micro-modelling technique is developed for the mason ...

Numerical study on factors that influence the in-plane drift capacity of unreinforced masonry walls

Katrin Beyer

Displacement‐based assessment procedures require as input reliable estimates of the deformation capacity of all structural elements. For unreinforced masonry (URM) walls, current design codes specify the in‐plane deformation capacity as empirical equations ...

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 ...
