Ensayos cuasi-estáticos cíclicos de muros delgados de concreto reforzado en edificios colombianos

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

The use of thin reinforced concrete walls (thickness of 8 to 12 cm) in Latin America has become a popular building construction practice in the last two decades. Several existing studies indicate that the inelastic deformation capacity could be limited and ...

Data-Interpretation methodologies for Non-Linear Earthquake Response Predictions of Damaged Structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

Seismic exposure of buildings presents difficult engineering challenges. The principles of seismic design involve structures that sustain damage and still protect inhabitants. Precise and accurate knowledge of the residual capacity of damaged structures is ...

Influence of load history on the force-displacement response of in-plane loaded unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding, Kiarash Mohtasham Dolatshahi

Empirical drift capacity models for in-plane loaded unreinforced masonry (URM) walls are derived from results of quasi-static cyclic shear-compression tests. The experimentally determined drift capacities are, however, dependent on the applied demand, i.e. ...

Validation of a FEA model of structural response of RC-cantilever beams strengthened with a (R-) UHPFRC layer

Eugen Brühwiler, Emmanuel Denarié, Hamid Sadouki

This paper focuses on modelling of structural response of RC cantilever beams retrofitted with a thin layer of Ultra High Performance Fibre Reinforced cement-based Composite (UHPFRC). The complex cracking phenomenon of the resulting RC-UHPFRC composite sys ...

Effect of dilatancy on a frictional weakening fault subjected to fluid injection

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Fluid injection at a pressure below the local minimum principal total stress in a fault may (re)activate shear crack propagation (hydroshearing). Because of the presence of asperities along the fault's surfaces, fault hydraulic width increase with slip. Sc ...

G: Fracture energy, friction and dissipation in earthquakes

Marie Estelle Solange Violay

Recent estimates of fracture energy G (') in earthquakes show a power-law dependence with slip u which can be summarized as G (') ae u (a) where a is a positive real slightly larger than one. For cracks with sliding friction, fracture energy can be equated ...

Properties of the shear stress peak radiated ahead of rapidly accelerating rupture fronts that mediate frictional slip

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Daniel Pino Muñoz

We study rapidly accelerating rupture fronts at the onset of frictional motion by performing high-temporal-resolution measurements of both the real contact area and the strain fields surrounding the propagating rupture tip. We observe large-amplitude and l ...

An empirically-based steady-state friction law and implications for fault stability

Marie Estelle Solange Violay

Empirically based rate-and-state friction laws (RSFLs) have been proposed to model the dependence of friction forces with slip and time. The relevance of the RSFL for earthquake mechanics is that few constitutive parameters define critical conditions for f ...

Seismic vulnerability assessment at urban scale for two typical Swiss cities using Risk-UE methodology

Pierino Lestuzzi, Angelo Garofano, Stefano Podesta, Patrick Bischof

This paper contains a seismic assessment at urban scale of the cities of Sion and Martigny in Switzerland. These two cities have been identified for the present research based on their importance regarding size and the characteristics of the building stock ...
