Evaluation of Total Reactive Oxide Ratios and Working Solution Ratios on Strength Development in Fly Ash-Based Geopolymers

Venkata Prasanna Bhagath Singh Gangapatnam

Fly ash-based geopolymers are being developed as sustainable alternate binders for producing concrete. The consistent production of a stable geopolymeric binder suitable for use in structural applications from alkaline activation of low-calcium fly ash was ...

Meso-scale modelling of ASR in concrete: effect of viscoelasticity

Jean-François Molinari, Mauro Corrado, Emil Gallyamov, Roozbeh Rezakhani

A meso-scale numerical model for simulating damage in concrete due to ASR is presented. It accounts for the internal structure of concrete including aggregates and mortar. ASR sites are explicitly represented. This model is extended to account for viscoela ...

Trilinear Model for the Out-of-Plane Seismic Assessment of Vertically Spanning Unreinforced Masonry Walls

Katrin Beyer, Michele Godio

Out-of-plane failure of masonry walls is often responsible for the partial collapse of unreinforced masonry structures. Modeling the out-of-plane response of these walls is therefore key in the assessment of existing buildings. The paper presents a new tri ...

Atmospheric and oceanic climate forcing of the exceptional Greenland ice sheet surface melt in summer 2012

Konrad Steffen

The NASA announcement of record surface melting of the Greenland ice sheet in July 2012 led us to examine the atmospheric and oceanic climatic anomalies that are likely to have contributed to these exceptional conditions and also to ask the question of how ...

A meso-mechanical model for concrete under dynamic tensile and compressive loading

Jean-François Molinari, Leonardo Snozzi, Fabrice Gatuingt

We present a computational model, which combines interface debonding and frictional contact, in order to investigate the response of concrete specimens subjected to dynamic tensile and compressive loading. Concrete is modeled using a meso-mechanical approa ...

A game of international climate policy solved by a homogeneous oracle-based method for variational inequalities

Marc Vielle

This paper presents a game-theoretic model for the international negotiations that should take place to renew or extend the Kyoto protocol beyond 2012. These negotiations should lead to a self-enforcing agreement on a burden sharing scheme to realize the n ...

Structural Analysis and Electronic Properties of Negatively Charged TCNQ: 2D Networks (TCNQ)(2)Mn Assembled on Cu(100)

Klaus Kern

A compound two-dimensional monolayer mixing Mn atoms and 7,7,8,8-tetracyanoquinoclimethane (TCNQ) molecules was synthesized by supramolecular assembly on a Cu(100) surface under ultrahigh-vacuum conditions. The interactions in the Mn(TCNQ)(2) network and i ...

Structural analysis of ultrafast extended x-ray absorption fine structure with subpicometer spatial resolution : Application to spin crossover complexes

Majed Chergui, Wojciech Gawelda, Van Thai Pham, Renske Marjan van der Veen

We present a novel analysis of time-resolved extended x-ray absorption fine structure (EXAFS) spectra based on the fitting of the experimental transients obtained from optical pump/x-ray probe experiments. We apply it to the analysis of picosecond EXAFS da ...

Modeling of rutting in asphalt flexible pavement

André-Gilles Dumont

This paper presents a finite element analysis modeling of rutting. The behaviors of the asphalt concrete is described using an elasto-viscoplastic constitutive relation, while an elastoplastic constitutive relation is used for the lower layers. The model a ...
