PILLARS AND GIRDERS1. What is the function of a pillar? Every ship of large size is provided with pillars and generally with (longitudinal) girders for the purpose of supporting the deck under which they are fitted. A pillar is accordingly subjected to a buckling load, which increases with a lower position of the pillar or an increase of the cargoes weight. This load is further dependent on the number of rows of pillars and the ship's breadth. The greater this number, the breadth remaining the same, the smaller the load a pillar has to bear, and, conversely, the larger the ship's breadth, with an equal number of pillars, the more the load allotted to each pillar will increase. Finally, the pillars will take up heavier loads in the proportion in which their spacing as well as their length are increased. элементы одинарного дна включают флоры, кильсоны-стрингеры и киль.
