Frame stability concerns the significance of second-order effects and is highlighted as an essential check for all frames in BS 5950 and EC3.
Whilst in many braced frames the effects will not be significant, designers should be confident in using the simple checks to determine frame sensitivity, and the simple rules to allow for such effects.
Second-order effects are introduced by considering the simple case of strut buckling, and then extends this to cover frames.
The course provides guidance on:
- Braced frames
- Continuous frames
- Portal frames
It covers the simple approaches in BS 5950 to allow for second-order effects, including the amplified sway method and use of Annex E.
