Failure in multiphase geomaterias

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

Topologie des champs de contraintes pour le dimensionnement des structures en béton armé

Neven Kostic

The stress field method, which is based on the lower bound theorem of plasticity, provides an unlimited number of solutions allowing to carry the applied loads to the supports for a given structure. This possibility which gives a large freedom to designing ...

TENSILE CREEP OF UHPFRC UNDER LOW AND HIGH STRESSES

Eugen Brühwiler, Emmanuel Denarié, Agnieszka Ewa Switek

The purpose of this paper is to investigate experimentally the UHPFRC time-dependent behavior under sustained tensile loading and to determine the effect of the stress level on the creep response. Uniaxial tensile creep tests were performed at various stre ...

Measurement of residual thermal stress in WC-Co by neutron diffraction

Daniele Mari

The temperature dependence of residual stresses in a WC-17.8vol.%Co cemented carbide was measured by neutron diffraction. The comparison of the WC lattice parameter within the WC-Co and within stress-free WC reference provides a measurement of lattice elas ...

Arterial biomechanics after destruction of cytoskeleton by Cytochalasin D

Nikolaos Stergiopoulos, Sylvain Roy, Paolo Silacci, Tyler Nerton Thacher

Vascular smooth muscle is a major structural element of the arterial wall. We examined the effects of cytoskeleton destruction, after administration of Cytochalasin D, on the biomechanical properties of porcine common carotids. Compared to untreated, maxim ...

Structural analysis of a composite bridge structure combining UHPFRC and prestressed concrete

Eugen Brühwiler, Hamid Sadouki, Cornelius Oesterlee

Reinforced concrete being the most applied construction material today performs very well in most applications but still lacks durability under severe environmental conditions. Especially existing structures built decades ago show degradation. Using Ultra- ...

New Connection System for Confined Concrete Columns and Beams. II: Theoretical Modeling

Yu Bai

The concept of confined concrete has been widely accepted throughout the structural engineering field, such as the spiral, steel tube, or carbon fiber composite shell confined concrete, etc. In the present study, this concept has not only been used in the ...

Reinforced concrete bridges under increased railway traffic loads

Andrin Herwig

The aim of this thesis is to provide rational engineering methods for the fatigue safety examination of existing railway bridges. Increasing railway traffic loading and enhanced structural analysis allow for higher exploitation of the capacity of bridge el ...

Model for predicting the UHPFRC tensile hardening response

Eugen Brühwiler, Emmanuel Denarié, John Wuest

Ultra High Performances Fibre Reinforced Concretes (UHPFRC) are characterised by an ex-tremely low permeability and outstanding mechanical properties. These characteristics make UHPFRC suitable for locally “harden” reinforced concrete structures subjected ...
