Facilitating the incorporation of VIP into precast concrete sandwich panels

Andrea Bassi, Thierry Voellinger, Matthew Leslie Heitel

This research focuses on the development of thin, load bearing, composite concrete facade elements containing high performance thermal insulation. A pilot project involving the construction of a detached house has been completed resolving issues related to ...

Upscaling of Friction Welding of Wood for structural Applications

Benjamin Hahn

The present work deals with the large-scale application of the friction welding bonding technology on timber. The investigations that are described in the following were carried out on a prototype of a welding machine that was previously developed for the ...

Audio-based Localization for Swarms of Micro Air Vehicles

Dario Floreano, Felix Stephan Schill, Meysam Basiri

Localization is one of the key challenges that needs to be considered beforehand to design truly autonomous MAV teams. In this paper, we present a cooperative method to address the localization problem for a team of MAVs, where individuals obtain their pos ...

Pressure tunnels in non-uniform in situ stress conditions

Anton Schleiss

The bearing capacity of prestressed concrete-lined pressure tunnels is governed by the in situ stress of rock mass, which generally has different magnitudes in the vertical and horizontal direction. Two cases were distinguished, based on whether the vertic ...

Tension Chord Model Modification for Uniaxial Unloading and Reloading in Elastic and Plastic States

Thomas Keller, Robert Koppitz

The bond properties between concrete and steel reinforcement influence structural stiffness and deformation behavior as a result of tension stiffening. In specific cases, the load-bearing capacity of engineering structures depends on the deformation behavi ...

Design and experimental verification of an innovative steel–concrete composite beam

Jean-Paul Lebet, Dimitrios Papastergiou

This paper deals with the design method and the experimental verification of a new type of steel–concrete composite beam under static and fatigue loading. The connection is an alternative solution for steel–concrete composite bridges suitable for prefabric ...

Granulation and bistability in non-Brownian suspensions

Matthieu Wyart

In granulation, a dense colloidal suspension is converted into pasty lumps by application of flow. Often, such lumps are bistable: each can exist either as a fluid droplet (with a shiny surface) or as a jammed granule, whose rough surface creates a bulk st ...

Modeling of axial and shear stresses in multilayer Sandwich beams with stiff core layers

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Michael Osei-Antwi

In order to optimize the load-bearing behavior of sandwich structures and adapt it to specific requirements, their core may be composed of layers of different materials with tailored properties. These layers may consist not only of soft foam or honeycomb m ...

Enhanced Groove Geometry for Herringbone Grooved Journal Bearings

Jürg Alexander Schiffmann

Although gas-lubricated herringbone grooved journal bearings (HGJB) are known for high rotordynamic stability thresholds, small clearance to diameter ratios are required for stable rotor operation. Tight clearances not only increase bearing losses but also ...

Foil Bearing Design Guidelines for Improved Stability

Jürg Alexander Schiffmann

Experimental evidence in the literature suggests that foil bearing-supported rotors can suffer from subsynchronous vibration. While dry friction between top foil and bump foil is thought to provide structural damping, subsynchronous vibration is still an u ...
