Résumé

In 1985, Sabir developed two membrane finite elements having an additional nodal degree of freedom (DRILLING
ROTATION). The main objective of this important development is to contribute in modeling the complex structures having
only simple geometrical shape. In this paper, a new analytical integration expression is developed in order to model structures
have complex geometrical shape. It is of importance to know how these elements will behave when they have irregular shapes.
