The columns are apertured at spaced intervals to attach beams having mating connectors. The columns include apertured vertical members which are shortened to terminate substantially above the floor plus unapertured posts which extend to the floor and overlap with each other along a distance preferably at least equal to the shortened distance. The upper ends of the posts are closed while the bottom ends of apertured members are open.
