During the evaluation of a deck slab , the application of inappropriate
dynamic amplification factors could have significant implication .
The dynamic Response of a deck slab only depended on many factors.

Les propriétés intrinsèques des argiles, notamment leur faible perméabilité, leur possibilité de cicatrisation ainsi qu’une bonne capacité de rétention des cations ont fait de ces matériaux des sites intéressants pour le ...
The unavailability of human vertebrae for experiments requiring research
models identical to the real, made with other materials that have the same
mechanical properties as that of the bone.
Since the intervertebral ...

Corrosion in industry is a phenomenon of current which are faced by maintenance crews and production of various units of the industrial pole of Arzew. This results in more or less prolonged stoppages of production lines, ...
The composites materials are widely used in various industrial sectors. These new materials are lightweight compared to conventional materials, and good mechanical properties. During services, theses materials are exposed ...
In this study we propose a method for prediction of the fatigue-life for different materials subjected to constant amplitude multiaxial proportional loading. We have planned a new fatigue criterion based on Crossland’s ...
This study relates to the Embrittlement by Hydrogen (FPH), under cathodic loading and at
ambient temperature, of a stainless steel, like on the comprehension of the physical mechanisms
of embrittlement associated.
Initially, ...
The main objective of this work is to study the impact behavior composite
materials and their behavior more precisely the impact of the ball by the method of
planning experiments. The studied materials are laminated to ...
Prévoir le comportement des structures en fatigue est un atout de la conception, car pour être compétitive, l’étude doit être optimisée au plus juste afin de répondre à un cahier des charges toujours plus exigeant. L’avènement ...
Like any concrete structure, casing bridges experiencing significant damage that can affect the life of the structure. To address these shortcomings, researchers have ceased trying to find solutions for the maintenance and ...
The response of buildings under seismic loads is a function of their structural characteristics, therefore the qualities and deficiencies associated with them. If the new structures meet the Algerian Earthquake Design ...
Delayed ettringite formation (DEF) is a pathology of cementitious materials that has been widely studied these past years. If ettringite forms only partially during the beginning of cement hydration (its solubility increases ...
The morphological particularity of the site of Oran as an abrupt fringe marked by ravines flowed by a plain that reaches the height of 110 meters submitted to different major risks such as the risk of the movement of the ...
In recent decades, many buildings in Algeria were made of reinforced concrete. The structures, in general, and the bridges, in particular, are subject to several chemical and mechanical reactions that can alter and influence ...
Sediments stemming from operations of dredgings raise numerous environmental and economic problems bound to their future. In the framework of disposal from negative effect to this waste, it is necessary to manage them by ...
The environmental degradation is the depletion of raw materials are allowed problems of the century. Cement plants consume each day hectares of land of clay and limestone, on the other hand the deposition of sediments Drag ...
Millions of cubic meters of sediment are dredged each year in the dams and deductions as a procedure of maintenance and prevention through the countries of the world .These sediments dredged ,considered as natural waste ...
