Common Structural Rules - Common Structural Rules for Bulk Carriers and Oil Tankers, January 2019 - Part 1 General Hull Requirements - Chapter 8 Buckling - Section 5 Buckling Capacity - 1 General
1 General
1.1 Scope
1.1.1 This section contains the methods for determination of the buckling capacity of plate panels, stiffeners, primary supporting members, struts, pillars, cross ties and corrugated bulkheads.
- Ch 8, Sec 3 for prescriptive requirements.
- Ch 8, Sec 4 for FE analysis requirements.
1.1.3 Ultimate buckling capacity
The ultimate buckling capacity is calculated by applying the actual stress combination and then increasing or decreasing the stresses proportionally until the interaction formulae defined in [2.1.1], [2.2.1], and [2.3.4] are equal to 1.0.
1.1.4 Buckling utilisation factor
The buckling utilisation factor of the structural member is equal to the highest utilisation factor obtained for the different buckling modes.
1.1.5 Lateral pressure
The lateral pressure is to be considered as constant in the buckling strength assessment.
