Numerical investigation of the role of masonry typology on shear strength

The force-displacement behavior of masonry elements depends on the properties of their constituents, mortar and unit, as well as on their typology, i.e., the shape and size of the units and the patterns they generate. Up until now, only few numerical studi ...

Quasi-static shear-compression tests on stone masonry walls with plaster: Influence of load history and axial load ratio

Katrin Beyer, Francesco Vanin, Shenghan Zhang, Michele Godio

This paper describes quasi-static cyclic shear-compression tests on six plastered single-leaf stone masonry walls. Of the six walls, four are tested under different axial load ratios, performing a cyclic load history with two cycles per increasing drift de ...

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 ...

A 2D typology generator for historical masonry elements

Katrin Beyer, Shenghan Zhang, Martin Hofmann

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 ...

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 ...

Micro-mechanical finite element modeling of diagonal compression test for historical stone masonry structure

Jean-François Molinari, Katrin Beyer, Nicolas Richart, Shenghan Zhang, Seyedeh Mohadeseh Taheri Mousavi

Simulating the force-deformation behavior of stone masonry is a challenging issue. This paper contributes to this topic by developing a detailed micro-modeling method using extrinsic cohesive elements. To consider contact and friction, a new node-to-node a ...
