Introduction/purpose: Structural design and calculation are based on the behavior of concrete and steel separately, without taking into account the contribution of stirrups in concrete confinement. The influence of confinement in structural modeling

In this paper, we present an analytical model to analyze reinforced and prestressed concrete beams loaded in combined bending, axial load and shear, in the frame of non linear elasticity. In this model, the equilibrium of the beam is expressed by sol

Pure aluminium has poor mechanical properties. For this purpose, the objective of this work is to study principally the influence of the incorporation of 3% copper, 2% silicon and less than one percent (1%) magnesium, which represent very important a

This work deals with the coupling between a periodic homogenization procedure, and a damage process occurring in a Representative Volume Element (RVE) of inclusion composite materials. We mainly seek, on the one hand to determine the effective mechan
