Section 4 Buckling control

4.1 General

4.1.1 The requirements in respect of the control of buckling of single skin and sandwich panels, including global buckling of structures, pillars and pillar bulkheads are given in this Section.

4.2 Single skin laminate

4.2.1 Where single skin laminate panels are subject to compressive loading likely to cause axial buckling, design calculations are to be submitted indicating the margin against failure.

4.3 Sandwich skin laminate

4.3.1 Where sandwich panel skin laminates are subject to compressive loading likely to cause axial buckling, design calculations are to be submitted indicating the margin against failure.

4.3.2 Where sandwich panels subject to compressive loading have skin thicknesses which are less than the minimum required by Pt 8, Ch 3, 2.3 Sandwich skin laminate, design calculations are to be submitted indicating the margin against failure due to wrinkling of the sandwich skin laminates.

4.3.3 Where production methods or the craft design gives rise to local distortion or irregularity of the sandwich, the designer is to make due allowance for the reduction in critical wrinkling stress.

4.4 Pillars and pillar bulkheads

4.4.1 In general, the requirements in respect of the control of buckling of pillars and pillar bulkheads are given in Pt 8, Ch 3, 10 Pillars and pillar bulkheads.
