+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.
