AD.2007-08.3.6 EC3 Slender Circular Hollow Sections
Slender circular hollow (pipe) sections may now be designed per Eurocode 3 (EN 1993-1-6:2007).
Eurocode 3 – Part 1 (EN 1993-1-1:2005) –hereafter EC3-6– states in Cl. 220.127.116.11 (5) that the design of slender circular hollow sections is to be based on the procedure in EN 1993-1-6. EC3 6 deals with the design of shell structures. EC3-6 does not, however, specify additional or modified safety factors. Therefore, the default safety factors from EN 1993-1-1 are used.
The program checks the plastic and buckling limit states for primary stresses based on the stress design method described in EC3-6.
Refer to D5.C.5.6 Design of Slender pipe sections to EN 1993-1-6 for details on the methodology and calculations used in this design.
