Section 2 Pillars

201. Application

Pillars supporting beams are to be in accordance with the requirements in this Chapter.

202. Pillars under Concentrated Loads, etc.

Special supports, by providing pillars or by other suitable means, are to be arranged at the ends and corners of deckhouses, in machinery spaces, at the ends of partial superstructures and under heavy concentrated loads.

203. Sectional Area of Pillars

1. The sectional area lowing formula:

of pillars which are made of steel, is not to be less than obtained from the fol-
