Stability of thin reinforced concrete walls under cyclic loads: State-of-the-art and new experimental findings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) walls may not achieve the expected ductile response but could possibly be triggered by out-of-plane displacements ...

Influence of boundary conditions on the out-of-plane response of brick masonry walls in buildings with RC slabs

Katrin Beyer, Marco Tondelli

In modern unreinforced masonry buildings with stiff RC slabs, walls of the top ﬂoor are most susceptible to out-of-plane failure. The out-of-plane response depends not only on the acceleration demand and wall geom-etry but also on the static and kinematic ...

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 ...

Snow instability evaluation: calculating the skier-induced stress in a multi-layered snowpack

Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen

The process of dry-snow slab avalanche formation can be divided into two phases: failure initiation and crack propagation. Several approaches tried to quantify slab avalanche release probability in terms of failure initiation based on shear stress and stre ...

Application of micro X-ray diffraction to investigate the reaction products formed by the alkali–silica reaction in concrete structures

Gervais Chapuis, Alla Arakcheeva, Philip Pattison

Alkali-silica reaction (ASR) is one of the most important deterioration mechanisms in concrete leading to substantial damages of structures worldwide. Synchrotron-based micro-X-ray diffraction (micro-XRD) was employed to characterize the mineral phases for ...

Influence of bond and anchorage conditions of the shear reinforcement on the punching strength of RC slabs

Fabio Brantschen

Reinforced concrete flat slabs constitute one of the most common and efficient modern construction methods. The design of such structural system might be governed by a brittle failure in the vicinity of the slab-column connection associated to punching she ...

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties

Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen

If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the locat ...

The Critical Shear Crack Theory for punching design: from a mechanical model to closed-form design expressions

Aurelio Muttoni, Miguel Fernández Ruiz

The Critical Shear Crack Theory (CSCT) is a consistent approach used for shear design of one- and two-way slabs failing in shear and punching shear respectively. The theory is based on a mechanical model allowing to determine the amount of shear force that ...

The Interplay of In Situ Stress Ratio and Transverse Isotropy in the Rock Mass on Prestressed Concrete-Lined Pressure Tunnels

Anton Schleiss

This paper presents the mechanical and hydraulic behaviour of passively prestressed concrete-lined pressure tunnels embedded in elastic transversely isotropic rocks subjected to non-uniform in situ stresses. Two cases are distinguished based on whether the ...

Physically based models to study the alkali-silica reaction

Karen Scrivener, Cyrille Dunant

The Laboratory of Construction Materials in Lausanne has been studying the alkali-silica reaction for more than 10 years, advancing the understanding of the reaction, and also producing microstructural models which can be used to predict quantitatively the ...
