A study on the crack presence effect on dynamical behavior of higher-order Quasi-3D composite steel-polymer concrete box section beams via DQFEM

Nassim Laouche, Ahmed Saimi, Ismail Bensaid, Mouloud Dahmane, Hassen Ait Atmane

This paper presents a dynamic and critical buckling analysis of the presence of a crack of steel-polymer concrete composite beams modelled using a refined quasi 3D beam theory. The beam model is a hollow steel box section filled with a…

Mechanical Stability Investigation of Advanced Composite Plates Resting on Elastic Foundations Using a New Four-Unknown Refined Theory

Yassine khalfi, Aboubakar Seddik BOUCHIKHI, Yassine BELLEBNA

A refined and simple shear deformation theory for mechanical buckling of composite plate resting on two-parameter Pasternak’s foundations is developed. The displacement field is chosen based on assumptions that the in-plane and transverse…

Contribution of longitudinal stiffener rigidity and position to bridge girder integrity

Emanuele Maiorana

To increase the elastic critical load of a plate, such as I-shaped cross-welded section of bridge girders, slenderness is usually reduced by dividing the web into subpanels, by means of transversal stiffeners and a longitudinal stiffener…

Influence of Internal Technological Defects on the Mechanical Properties of Structural CFRP

Dmitriy Lobanov, Stanislav Slovikov, Ekaterina Lunegova

The use of carbon-fiber composite materials (CFRP) in critical cases implies an increase in the resistance to the stability of their mechanical properties. For the purpose of in-depth analysis of defects in the experiments, an integrated…
