Combined Shear-Flexural Verification Of In Plane Loaded Reinforced And Unreinforced Masonry Walls

Lorenzo Benedetti

The safety verification of in-plane loaded masonry panels requires the evaluation of at least three different collapse conditions connected with overturning, shear sliding, and shear - compression failure at the panels' toe. In reinforced panels, the resis ...

An Analytical Method to Predict the Structural Behavior of Timber-Concrete Structures With Brittle-to-Ductile Shear Connector Laws

Eugen Brühwiler, Luca Sorelli

Timber-Concrete Composite (TCC) structures allow taking synergistic advantage of the properties of both materials to optimize the overall performances in terms of lightness, slenderness, acoustic insulation, vibrational behaviour and environmental footprin ...

Thermomechanical characterization of a balsa-wood-veneer structural sandwich core material at elevated temperatures

Thomas Keller, Anastasios Vassilopoulos, Chao Wu, Niloufar Vahedi

The tensile, compressive and shear behavior of standardized specimens cut from a veneered balsa wood used as structural sandwich core was investigated at ambient temperatures of up to 250 degrees C. The average moisture content was 9.1%. The specimens' res ...

X-Shell Pavilion: A Deployable Elastic Rod Structure

Mark Pauly, Florin Isvoranu, Tian Chen, Francis Julian Panetta, Etienne Bouleau

We present the X-Shell pavilion, a lightweight structure composed of elastic beam elements joined in a special layout that allows easy on-site deployment. The structure’s undeployed assembly configuration lies mostly flat and is easy to build, consisting o ...

Can timber lower the environmental impact of tall buildings?

Corentin Jean Dominique Fivet, Catherine Elvire L. De Wolf

The building sector is responsible for 30% of anthropogenic greenhouse gas (GHG) emissions (UNEP, 2009). Recent energy efficiency measures have helped reduce the operational carbon related to the use phase of the building, but a lack of industry attention ...

Shape memory alloys in fibre-reinforced polymer composites

Véronique Michaud, Amaël Maximilien Cohades

This article reviews the current state-of-the-art in the applications of shape memory alloy (SMA) wires into high performance fibre reinforced polymer composite materials (FRPs). SMAs have been investigated to date to address four main areas of properties ...
