This study embodies a comparation of the behavior of a symmetric fixed-end beam with retangular cross section analysed by the finite element method and by the theory of mechanics of materials, adopting in the last analysis two hypotheses relative to the axis of the beam: 1. The axis is straight; 2. The axis is the line passing through the midheight of the cross section. The analysis of the beam, according to the second hypothesis, leads to better results than the first one. The limitation imposed by NB-1 Standard Code (inclination of haunchs smaller than 1/3) is correct.
