Stiffness, force and drift capacity of in-plane loaded modern unreinforced brick masonry walls

In countries of low to moderate seismicity, such as Switzerland, unreinforced masonry (URM) is mainly used in residential buildings due to its good insulation capacity and fire resistance along with a fair compressive strength. URM walls however show a lim ...

Thermal Activation, Intermittency and Size Effects in the Plastic Deformation of Cast Aluminium Microwires

Suzanne Godelieve Alphonsine Verheyden

The microcasting process is a scaled-down investment casting process in which molten metal is pressure-infiltrated and directionally solidified in water-soluble moulds. It was previously developed to produce metallic microwires with a diameter (D) between ...

Periodic cellular aluminum structures for space applications

Florian Thibaut Gallien

Mass is one of the crucial parameters for hardware that has to be placed in Earth orbit. Due to its harsh environment, a material with highest specific properties is desired to achieve space missions. The rise and development of new technologies, such as a ...

Improving the collapse risk of steel structures with high-performance steel

Dimitrios Lignos

With the advent of material science, high-performance steel materials have been developed for seismic applications that potentially reduce the earthquake-induced collapse risk of steel frame buildings. The High Yield Point (HYP400) steel is one of those ma ...

Full-Scale Testing of Deep Wide-Flange Steel Columns under Multiaxis Cyclic Loading: Loading Sequence, Boundary Effects, and Lateral Stability Bracing Force Demands

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper discusses the findings from 10 full-scale steel column tests subjected to multiaxis cyclic loading. The columns use deep wide-flange cross sections typically seen in steel moment-resisting frames designed in seismic regions. The effects of bound ...

Effect of Fiber Orientation and Specimen Thickness on the Tensile Response of Strain Hardening UHPFRC Mixes with Reduced Embodied Energy

Emmanuel Denarié, Amir Hajiesmaeili

Ultra-high performance fiber reinforced concretes (UHPFRC) have demonstrated their potential to contain the explosion of maintenance costs (Economy and Environment) for civil engineering structures, due to their extremely low permeability associated with t ...

A mechanical model for failures in shear of members without transverse reinforcement based on development of a critical shear crack

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Cavagnis

In this paper, a mechanical model consistent with the main assumptions of the Critical Shear Crack Theory (CSCT) is proposed for shear design of slender concrete members without shear reinforcement. To that aim, the shear force that can be transferred thro ...
