Dans le domaine des bâtiments et des pente

de la construction et une surcharge considérable, on demande de réduire au minimum la hauteur des poutres. Cette réduction est généralement dictée par le coût global de la construction*
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.

Pour un bâtiment à plusieurs étagea, la réduction de la hauteur des poutres supportant les plancher* permet d'en augmenter le nombre pour une hauteur totale du

In the area of buildings and slopes

construction and considerable overload, it is requested to minimize the height of the beams. This reduction is generally dictated by the overall cost of construction *
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.

tion can be absolute due to the presence of existing buildings * Reducing the height of the beams can therefore,

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.
