Comportement des éléments en béton armé fléchis sous charge cyclique

For various types of civil structures such as bridges, skyscrapers and other slender towers, oil rigs as well as runaways, dynamic loading is predominant. This holds true especially for bridges where loads have increased considerably in the last hundred ye ...

Extended Integrated Force Method for the analysis of prestress-stable statically and kinematically indeterminate structures

Gennaro Senatore, Yafeng Wang

This paper presents a new force method to predict the structural response of statically and kinematically indeterminate systems that can be stabilized through prestress, i.e. prestress-stable structures. This new force method, here named Extended Integrate ...

Prediction of autogenous shrinkage of cement pastes as poro-visco-elastic deformation

Karen Scrivener, Zhangli Hu, Pietro Lura

Precise and robust predictions of autogenous shrinkage of high performance concrete are essential to limit self-induced stresses and cracking in modern concrete structures. This paper presents predictions of autogenous shrinkage for three cement pastes of ...

Building Duration / El Portico de los Huespedes

Patricia Guaita, Raffael Baur, Sony Devabhaktuni

El Portico de los Huéspedes is a pedagogical, design-research project that tests the possibility of an open-ended architecture, where duration links between past and future. It is a work of architecture as becoming: ‘work’ meaning the structure, rhythms an ...

Cyclic tensile-compressive tests on thin concrete boundary elements with a single layer of reinforcement prone to out-of-plane instability

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso, Lisandro Arturo Jimenez Roa

The growing need for residential housing in Latin American countries has led to the construction of reinforced concrete buildings with wall thicknesses as low as 8–10 cm. Such walls have typically only a single layer of vertical rebars and are therefore pa ...

Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...

EPFL2017

Designing new concrete members and assessing the strength of existing elements subjected to in-plane stress state conditions is often conducted by means of Stress Fields (SF) and Strut-and-Tie Models (STM). These methods are usually accounting for identica ...

We present a research-in-progress project on teaching business design at an engineering school. We describe our teaching approach based on experiential learning, systems thinking and service-dominant logic. We highlight how we try, by repetition, to help t ...

Static and Fatigue Shear Strength of Reinforced Concrete Slabs Under Concentrated Loads Near Linear Supports

Francisco Manuel Maciel Natário

Reinforced concrete slabs without shear reinforcement under concentrated loads near linear supports are typical cases of bridge deck slabs, transfer slabs or pile caps. Such members are often designed or assessed in shear/punching shear with code provision ...

Concrete structures, contrary to steel or timber structures, have not been traditionally considered as significantly sensitive to fire conditions. As a consequence, their performance in fire conditions has generally been assessed on the basis of quite simp ...
