C'est le cas notamment des ponts enjambant une enteront*, un canal ou une bois ferrée; la réduction de la hauteur permet de réduire" dans des proportions importan.

This is the case in particular of bridges spanning an enteront *, a canal or a railway wood; the reduction of the height makes it possible to reduce "in importan proportions.

For a multi-storey building, reducing the height of the beams supporting the floors * increases the number for a total height of the

apart from the effect of shrinkage, these stresses do not cause deformations in the concrete. When the beam is stressed by overloads, these constraints are favorable with regard to the appearance of possible small cracks.
