Seismic Behavior of Shell-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

Unanchored steel tanks subjected to strong ground motion may experience rocking motion if the moment generated by the inertial mass of the content stored is greater than the resisting moment provided by the weight of the tank and its content. Rocking of th ...

Seismic Behavior of Shell-to-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

A study of non-anchored tanks found in Switzerland (Koller, 2003) revealed that the plastic rotation of the shell-to-bottom connection in four of the six tanks studied did not satisfy the 0.2 radians limit established by the Eurocode (Eurocode-8, 2005). Th ...

Kinetic study of formic acid oxidation on Ti/IrO2 electrodes prepared using the spin coating deposition technique

Christos Comninellis, Stéphane Fierro

In the first part of this paper, IrO2 electrodes produced by thermal decomposition of H2IrCl6 precursor were manufactured using the spin coating deposition technique, where centrifugal forces spread the precursor solution with simultaneous evaporation of t ...

The evolution of Ap stars

Pierre North

The many peculiarities of Ap stars (not only chemical ones, but also magnetic field and slow rotation) may vary during the main-sequence evolution of these stars. We review here briefly the evidences found in the last thirty years for such evolution, with ...

Orion MinAngle: A flexure-based, double-tilting parallel kinematics for ultra-high precision applications requiring high angles of rotation

Reymond Clavel, Patric Pham

If you need to design ultra-high precision devices for mechanisms with multiple axes there are not a lot of ways leading around flexure-based joints. Using this type of articulations totally eliminates backlash and friction and is, by this, providing an ac ...

Elevated atmospheric boundary layer over the Swiss Alps during the August 2003 heat wave

Hubert van den Bergh, Bertrand Calpini, Valentin Simeonov, Marc Parlange, Ioan Balin

An unusual elevated atmospheric boundary layer (ABL) at altitudes of Lip to 5000 m was observed, using a combination of elastic and water vapor lidars, during a 10-day period in 2003. There was a persistent stationary anticyclonic regime over Western Europ ...
