A Fast Offshore Cruiser - Appendices. A.2. - Hull frames/floors/bulkheads.

(cm³) were (cm³)

C = 1800 for floors @ centreline, 817 for join between floor and frame

F inversely relates to , can be taken as 0.25

h = plating design head (m)

s = floor / frame spacing (m)

l = frame floor chord length (m)

s _a = 0.42*MoR, for laminated frame (N/mm²)

N = 1 @ centreline, 0.5 @ 1/3^rd girth, 0 for frames and floors not in way of keel

W_k = keel weight (N)

Y_k = Lever from CofG of Keel to centre of floor

n = number of floors in way of keel

Cold moulded wood bulkhead calculations.

s = stiffener spacing (mm)

c = 1 for flat plate

p = 0.01*h, h = depth of bulkhead (m)

k = 0.5 for cold moulded

s _a = 0.5*MoR, for cold moulded (N/mm²)

Bulkhead stiffener calculations.

Definitions as for "frame & floors section modulus (SM) calculations" except: -

C = 619

h = depth of bulkhead (m)

l = distance between supports (m)
