L'encyclopédie vitruvienne aujourd'hui?

Édifice inaugural du De Architectura, la Tour des Vents d’Andronikos de Kyrros nous montre comment Vitruve se forge, dans le sillage de Varron, une conception augmentée de l’architecture qui ne se limite pas à la construction d’édifices: aedificatio,, mais ...

Proposed Updates to the ASCE 41 Nonlinear Modeling Parameters for Wide-Flange Steel Columns in Support of Performance-Based Seismic Engineering

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Alexander Riley Hartloper

Nonlinear static and dynamic analyses are utilized by engineers for performance-based seismic risk evaluation of new and existing structures. In this context, nonlinear component modeling criteria are typically based on ASCE 41 guidelines. Experiments on w ...

Structure from sound with incomplete data

Martin Vetterli, Ivan Dokmanic, Gilles Baechler, Miranda Krekovic

In this paper, we consider the problem of jointly localizing a microphone array and identifying the direction of arrival of acoustic events. Under the assumption that the sources are in the far field, this problem can be formulated as a constrained low-ran ...

Waldstadt, entre vision stratégique et logique de protection

Dans un contexte de lutte contre le mitage du paysage, la prise en compte des enjeux liés à la transition vers la durabilité encourage la recherche de nouvelles approches pour les territoires métropolitains du Plateau suisse. Le devenir de certains sites, ...

Experimental and Numerical Evaluation of Steel Columns for Performance-Based Seismic Assessment of Steel Moment Frames

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Alexander Riley Hartloper

This paper summarizes the findings of a long term experimental program corroborated with detailed finite element simulations that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames (MRFs) designed in highly seismic ...

Internal slab-column connections under monotonic and cyclic imposed rotations

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

Reinforced concrete flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate seismicity. Current codes of practice determine the displacement capacity of slab-column connections using empi ...

Seismic behaviour of slab-column connections without transverse reinforcement

Ioannis Sokratis Drakatos

Reinforced concrete (RC) flat slabs supported by slender columns are often used as gravity load resisting system for buildings in regions of moderate and high seismicity. Such buildings are typically braced by RC walls, which carry the largest portion of t ...

Punching of flat slabs supported on rectangular columns

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari

This paper investigates the structural behaviour of RC flat slabs supported on rectangular interior columns and the influence of the loading conditions (one or two-way bending) on their punching shear strength. The punching shear strength of slabs at recta ...

Piezoelectric AlScN thin films: A semiconductor compatible solution for mechanical energy harvesting and sensors

Paul Muralt, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Andrea Mazzalai, Mahmoud Hadad, Nachiappan Chidambaram

The transverse piezoelectric coefficient e31,f of Al1-xScxN thin films was investigated as a function of composition. It increased nearly 50% from x = 0 to x = 0.17. As the increase of the dielectric constant was only moderate, these films are very suitabl ...

Poinçonnement non symétrique des dalles en béton armé

Luca Tassinari

Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...
