A beam fixed at both ends, as shown in the Fig, has a F=20 kN concentrated load applied at the centre of the span. The beam structure is supported from the bottom, by a linear spring, with k=400 N/cm. In addition, the beam structure is a attached to the adjacent vertical walls through two truss elements, with cross-sectional area of A= 11.55 x10-3 cm².
