Influence of cracking and rough surface properties on the transfer of forces in cracked concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Max Tirassa

Aggregate interlocking is acknowledged as one of the most significant actions transferring shear forces in cracked concrete structures and has been investigated for several decades. Despite the many experimental programmes and previous efforts to develop m ...

The transfer of forces through rough surface contact in concrete

Max Tirassa

Aggregate interlocking is a phenomenon occurring when the opposite sides of a concrete crack slide relative to each other. Due to surface roughness, protruding material from one crack-side can engage with the opposite one and thus exchange forces. This aff ...

Stiffness and Strength Estimation of Damaged Unreinforced Masonry Walls Using Crack Pattern

Katrin Beyer

After an earthquake, the residual stiffness and strength of structural elements are typically estimated based on a qualitative visual inspection of cracks that is prone to error. In this paper a new approach is proposed to automatically estimate the update ...

Two-dimensional fatigue debonding in GFRP/balsa sandwich panels

Thomas Keller, Anastasios Vassilopoulos, Aida Cameselle Molares

An experimental investigation of the two-dimensional (2D) debonding behavior of GFRP/balsa sandwich panels with embedded circular disbonds at the face sheet/core interface subjected to out-of-plane fatigue loads was conducted. The constant amplitude fatigu ...

Fatigue safety verification of a steel railway bridge using short term monitoring data

Eugen Brühwiler, Bartlomiej Wojciech Sawicki

The case study of the fatigue safety examination of the 120 years old steel riveted bridge carrying a single railway track on two main girders is presented. The overall assessment according to the Swiss Standard SIA 269 for existing structures indicated su ...

Analysis of runaway electron expulsion during tokamak instabilities detected by a single-channel Cherenkov probe in FTU

Gabriele Grosso, Cristian Galperti, Filippo Bagnato

The expulsion of runaway electrons (REs) during different types of tokamak instabilities is analysed by means of a Cherenkov probe inserted into the scrape-off layer of the FTU tokamak. One such type of instability, the well-known tearing mode, is involved ...
