WW – Water filled weight
W – Weight
D1 – Displacement case 1
T1,T2,T3 – Thermal Case 1,2 & 3
P1 – Pressure Case 1
HP – Hydro Pressure
F1 - Concentrated Force Case 1
U1 – Uniform load case 1
U2 - Uniform load case 2
5.0 CONCLUSION:
Based on the supports, under all load cases are analysed.
Loads on Support are within the allowable value.
Stresses at all locations are within the allowable limit as per code.
