Numerical Modeling of FRP-Strengthened Masonry Structures Using Equivalent Frame Models

Katrin Beyer, Francesco Vanin, Ivana Bozulic

The present study focuses on enhancing the seismic resistance of existing masonry structures. To that aim, the use of fiber-reinforced polymer (FRP) strengthening serves to improve structural behaviour by attaching FRP strips to the masonry walls. Despite ...

Uncertainties in the Seismic Assessment of Historical Masonry Buildings

Katrin Beyer, Francesco Vanin, Igor Tomic

Seismic assessments of historical masonry buildings are affected by several sources of epistemic uncertainty. These are mainly the material and the modelling parameters and the displacement capacity of the elements. Additional sources of uncertainty lie in ...

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 ...

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 ...

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 ...

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

Katrin Beyer, Shenghan Zhang, Francesco Vanin, 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 ...

Equivalent frame models for in-plane and out-of-plane response of unreinforced masonry buildings

Francesco Vanin

The seismic assessment of masonry buildings, both modern unreinforced masonry (URM) buildings and historical heritage constructions, is a complex task, characterised by a several sources of uncertainty, which regard the appropriate modelling of strategy th ...

Application of a Point Estimate Method for incorporating the epistemic uncertainty in the seismic assessment of a masonry building

Katrin Beyer, Francesco Vanin

Several sources of uncertainty affect the assessment of existing buildings, including uncertainties associated with the material properties and the displacement capacity of the elements. In engineering practice, Monte Carlo simulations of the nonlinear sei ...

Seismic retrofit of cultural heritage buildings – when less is more

Katrin Beyer, Francesco Vanin, Michele Godio, Andrea Penna

In 1356, Basel was subjected to an earthquake with an estimated magnitude of 6.6; it is the largest known historical earthquake in central northern Europe. During this earthquake and the fire that followed large parts of Basel were destroyed. Such an event ...

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 ...

Estimates for the stiffness, strength and drift capacity of stone masonry walls based on 123 quasi-static cyclic tests reported in the literature

Katrin Beyer, Francesco Vanin, Dario Zaganelli, Andrea Penna

This paper summarises 123 existing quasi-static shear–compression tests on stone masonry walls and evaluates the results to provide the input required for the displacement-based assessment of stone masonry buildings. Based on the collected data, existing c ...
