5 Side frame sections

  5.1 Frames shall be fabricated symmetrical sections with integral upper and lower brackets and shall be arranged with soft toes.

  5.2 The side frame flange shall be curved (not knuckled) at the connection with the end brackets. The radius of curvature shall not be less than r, in mm, given by:

where bf and tf are the flange width and thickness of the brackets, respectively, in mm. The end of the flange shall be sniped.

  5.3 In ships less than 190 m in length, mild steel frames may be asymmetric and fitted with separate brackets. The face plate or flange of the bracket shall be sniped at both ends. Brackets shall be arranged with soft toes.

  5.4 The frame web thickness ratio of frames shall not exceed the following values:

  • .1 60 k0.5 for symmetrically flanged frames;

  • .2 50 k0.5 for asymmetrically flanged frames;

where:
k = 1 for ordinary hull structural steel;
k = 0.78 for steel with yield stress of 315 N/mm2; and
k = 0.72 for steel with yield stress of 355 N/mm2.

The outstanding flange shall not exceed 10 k0.5 times the net flange thickness.
