Stresses and displacements in steel-lined pressure tunnels and shafts in anisotropic rock under quasi-static internal water pressure

Steel-lined pressure tunnels and shafts are constructed to convey water from reservoirs to hydroelectric power plants. They are multilayer structures made of a steel liner, a cracked backfill concrete layer, a cracked or loosened near-field rock zone and a ...

Performance of punching shear reinforcement under gravity loading: Influence of type and detailing

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul, Fabio Brantschen

The performance of 11 different shear reinforcement systems against punching of inner slab-column connections under gravity loading was compared on the basis of experiments on 12 full-scale specimens, 8 of them newly reported. The slab geometry and flexura ...

Bond behaviour of straight, hooked, U-shaped and headed bars in cracked concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Duarte Miguel Viúla Faria, Fabio Brantschen

Most classic investigations on bonding properties in reinforced concrete have been performed on the basis of pull-out tests, where a reinforcement bar is pulled out from an uncracked concrete cylinder, prism or cube. In these tests, the bond is governed by ...

Electro-mechanical sensing in freestanding monolayered gold nanoparticle membranes

Jürgen Brugger

The electro-mechanical sensing properties of freestanding monolayered membranes of dodecanethiol coated 7 nm gold nanoparticles (NPs) are investigated using AFM force spectroscopy and conductive AFM simultaneously. The electrical resistance of the NP membr ...

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 ...

System transverse in-plane shear stiffness of pultruded GFRP bridge decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

The static transverse behavior of two pultruded GFRP deck systems with trapezoidal (DS) and triangular (AS) cell cross-sectional geometry was experimentally investigated in order to study their transverse in-plane shear stiffness. Symmetric three-point ben ...

Homoclinic snaking in plane Couette flow: bending, skewing and finite-size effects

Tobias Schneider

Invariant solutions of shear flows have recently been extended from spatially periodic solutions in minimal flow units to spatially localized solutions on extended domains. One set of spanwise-localized solutions of plane Couette flow exhibits homoclinic s ...

Composite model for predicting the punching resistance of R-UHPFRC-RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...

Design and exploration of externally post-tensioned structures using graphic statics

Corentin Jean Dominique Fivet

Funicular structures, which follow the shapes of hanging chains, work in pure tension (cables) or pure compression (arches), and offer a materially efficient solution compared to structures that work through bending action. However, the set of geometries t ...
