Section 3 Side Girders

301. Arrangement of Side Girders

Where the breadth of ship measured at the top of floors exceeds 4 m , side girders are to be ar- ranged at a suitable spacing.

302. Construction and Scantlings

1. The thickness of webs of side girders for the midship part is not to be less than obtained from the following formula. However, beyond the midship part, the thickness may be gradually reduced to- ward the ends and it may be 0.85 times the midship value at the end parts:

2. The thickness of face plates of side girders is not to be less than the thickness of webs and the breadth is not to be less than obtained from the following formula. However, beyond the midship part, the sectional area may be gradually reduced toward the ends and it may be 0.8 times the midship value at the end parts :

3. The heights of side girders at their ends are to extend to the top of floors or bottom transverse girders.

303. Side Girders in Engine Room

The thickness of webs and face plates of side girders in the engine room are not to be less than the thickness of webs and face plates of centre girders specified in 201. respectively.
