Performance of punching shear reinforcement under gravity loading: Influence of type and detailing

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul, Fabio Brantschen

The performance of 11 different shear reinforcement systems against punching of inner slab-column connections under gravity loading was compared on the basis of experiments on 12 full-scale specimens, 8 of them newly reported. The slab geometry and flexura ...

The Critical Shear Crack Theory for punching design: from a mechanical model to closed-form design expressions

Aurelio Muttoni, Miguel Fernández Ruiz

The Critical Shear Crack Theory (CSCT) is a consistent approach used for shear design of one- and two-way slabs failing in shear and punching shear respectively. The theory is based on a mechanical model allowing to determine the amount of shear force that ...

A new mechanical framework to interpret weak layer and slab fracture in the propagation saw test

Johan Alexandre Philippe Gaume, Lorenzo Benedetti

This work aims to provide a mechanical model for the Propagation Saw Test (PST) based on the Euler-Bernoulli beam, allowing a description of the slab and weak layer stress states in the quasi-static regime. We assume an elastic-perfectly brittle model as c ...

Numerical prediction of peri-implant bone adaptation: Comparison of mechanical stimuli and sensitivity to modeling parameters

John Botsis, Joël Cugnoni, Marco Piccinini

Long term durability of osseointegrated implants depends on bone adaptation to stress and strain occurring in proximity of the prosthesis. Mechanical overloading, as well as disuse, may reduce the stability of implants by provoking bone resorption. However ...

Multifunctional shape memory electrodes for dielectric elastomer actuators enabling high holding force and low-voltage multisegment addressing

Herbert Shea, Samuel Rosset, Nadine Besse, David James McCoul

We present a novel configuration of a dielectric elastomer actuator (DEA) using electrodes made of a shape-memory polymer. DEAs are an efficient class of flexible electromechanical transducer. They have been incorporated into a variety of elegant devices, ...

Limit states of modern unreinforced clay brick masonry walls subjected to in-plane loading

Katrin Beyer, Sarah Petry

Recent research showed that the in-plane horizontal displacement capacity of unreinforced masonry (URM) walls depends on numerous factors that are not yet captured by current empirical drift capacity models; e.g., axial stress, shear span, geometry of the ...

Force-displacement response of unreinforced masonry walls for seismic design

Sarah Petry

In regions with low to moderate seismicity, unreinforced masonry (URM) is commonly used for the construction of low to mid-rise buildings. When these structures are subjected to seismic loading, the stiff URM walls attract considerable part of the lateral ...

Evaluating snow weak-layer failure parameters through inverse finite element modelling of shaking-platform experiments

Johan Alexandre Philippe Gaume

Snowpack weak layers may fail due to excess stresses of various natures, caused by snowfall, skiers, explosions or strong ground motion due to earthquakes, and lead to snow avalanches. This research presents a numerical model describing the failure of "san ...
