Exercise $1$:

Evaluate the Eulerian Buckling load for the steel columns of the structures reported in the figure:

Data:

$E=210000$MPa

Considering the beam exposed in the figure, develop the following points:

Assess the maximum value of shear in section and $($:$V_B^R\}$ and maximum moment in section $B(M_B)$ according to fundamental combination.

Design the longitudinal reinforcement in section B$.$

Design the transversal reinforcement for the maximum shear load on support B$.$
