Modélisation d'un Poteau à section variable

[Anonymous]

Salut tout le monde

J'ai à modéliser, dans le cadre de mon PFE, un bâtiment comportant des poteau à section variable sur Robot, mais apparemment le logiciel n'offre pas cette possibilité. une solution ?

J'ai penser à le diviser en plusieurs poteaux de sections constatante, mais j aurai certainement des problèmes d'excentrement (pose des poutres et dalles) sachant que les poteau se trouvent au niveau de la façade .

Vous trouverez ci joint un schéma simplifié de deux poteau aux niveau de deux étage (je n'ai pas de plans numériques puisque les travail est un travail d'expértise sur des plan déjà imprimés)

Merci d'avance

Thanks Mr.Artur.Kosakowski for the solution.

in this case, we use an equivalent section for the bars ?

You can use tapered sections for bars 1 and 2.

this type of section in available only in steel design, But it's not the case in concrete design ???

Indeed they are not supported in the RC Design modules but can be used for static analysis of a model.

There is a solution. we define a beam with variable section then we change the property beam to colomn.
