RR 22.10.00-3.1 Tapered Member Design per EC3
Design of tapered members per EN 1993-1-1:2005 is now available in STAAD.Pro.
STAAD.Pro can design the following section profiles per EN 1993-1-1:2005:
- tapered I-section (constant flanges, web tapered)
- tapered tube (tapered square hollow section)
- tapered pipe (tapered round hollow section)
A new design parameter, HGT, has been added for use with the design of tapered I-sections. Other design parameters directly related to the tapered member checks are LY and EFT.
The following clauses of EN 1993-1-1:2005 are checked for tapered sections:
- 6.2.3 - tension
- 6.2.4 - compression
- 6.2.6 - shear
- 6.2.5 - moment
- 6.2.7 - torsion:
- (1) - pure torsion
- (5) - yield criteria for interaction of axial, bending and shear (including shear from torsion)
- (9) - reduced shear due to torsion
- 6.2.8 - reduced moment due to shear
- 6.2.9.1 - combined moment and axial force
- BB.3.2 - Stable length for tapered members (applies to tapered I-sections) - see Tapered Members
