 +Deformed and undeformed shapes are plotted, plus the bending moment.
 +
 +An equal imposed deflection is imposed at the top-left corner, stiffness has been evaluated based on the associated reaction force.
 +
 +The three frame structures stiffness is reported below:
 +  * $b/a=1/5$:  $k=7.29k_\mathrm{ref}$
 +  * $b/a=1/1$:  $k=5.60k_\mathrm{ref}$
 +  * $b/a=5/1$:  $k=3.38k_\mathrm{ref}$
 +where $k_\mathrm{ref}$ is the stiffness of the single upright member, taken as a reference.
 +
 +Beam cross section is uniform along the frame, and very slender.
