Quasi-static monotonic and cyclic tests on composite spandrels

In modern unreinforced masonry (URM) walls, the vertical piers are connected at the storey levels by reinforced concrete (RC) ring beams or RC slabs. Particularly, in the outer walls, the spandrel element also includes a masonry spandrel on top of the RC b ...

Applications of Stress Fields to Assess the Behavior and Strength of Coupling Beams subjected to Seismic Actions

Aurelio Muttoni, Miguel Fernández Ruiz

Horizontal loading due to earthquake or wind is usually the governing action for design of reinforced concrete cores in medium to tall buildings. Building cores designed to resist these actions must be dimensioned to resist tributary vertical loads and lar ...

Computation of accommodation coefficients and the use of velocity correlation profiles in molecular dynamics simulations

Peter Spijker

For understanding the behavior of a gas close to a channel wall it is important to model the gas-wall interactions as detailed as possible. When using molecular dynamics simulations these interactions can be modeled explicitly, but the computations are tim ...

The inspection of retaining walls using GPR

Alexis Kalogeropoulos

In hilly regions, retaining walls along roads, motorways and railway lines are numerous. In some cases the knowledge of the details of the construction is limited. If rehabilitation work becomes necessary, a detailed knowledge of the construction is desira ...

Quasi-static cyclic tests and plastic hinge analysis of RC structural walls

Katrin Beyer, Alessandro Dazio

This paper presents the results of quasi-static cyclic tests on six reinforced concrete (RC) walls performed at the ETH Zurich. These large-scale tests investigate the effect of different vertical reinforcement contents and different reinforcement ductilit ...

Upper bound limit analysis of meso-mechanical spandrel models for the pushover analysis of 2D masonry frames

Katrin Beyer, Alessandro Dazio

In this paper, a numerical model for the pushover analysis of in-plane loaded unreinforced masonry walls is presented. For the analysis of the walls, which consist of vertical piers connected by horizontal masonry spandrels, an equivalent frame model is ad ...

Effect of inclined ribs on the Aero-Thermal performance of a trailing edge cavity with crossing jets

Emanuele Facchinetti, Tony Arts

The present contribution is devoted to the aero-thermal experimental study of a trapezoidal cross-section model, reproducing a trailing edge cooling cavity with one rib-roughened wall and slots along two opposite walls. Four rib geometries are compared to ...

The effect of tissue geometry on the activation recovery interval of atrial myocytes

Vincent Jacquemet

The propagation of electric activity inside a realistically-shaped, thick-walled model of the atria was studied. The membrane kinetics was based on the formulations of Courtemanche, Ramirez and Nattel. In spite of the assumed uniformity of all kinetics par ...

Application of Microstencil Lithography on Polymer Surfaces for Microfluidic Systems with Integrated Microelectrodes

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Nao Takano

Microstencil lithography, a resistless, single-step direct vacuum patterning method, is one of promising methods for metal micropattern definition on polymer substrates that are not suitable for conventional photolithography. We propose to apply microstenc ...

Pullout forces and friction in multiwall carbon nanotubes

William Curtin

Molecular dynamic calculations of pullout in multiwall carbon nanotubes (CNTs) demonstrate that inner walls with fractured ends have pullout forces similar to3-4 times larger than those for capped ends, due to deformation of the fractured end, quantitative ...
