Flexural Buckling

The Flexural Buckling Check is executed according to EN 1993-1-3 art. 6.2.2 and EN 1993-1-1 art. 6.3.1.

Table 6.3 regarding the buckling curves is revised as follows:

	Description	about axis	Curve
1	I section	y-y z-z	a b
101	Asymmetric I section	y-y z-z	a b
114	Cold formed C section	any	b
116	Cold formed C-Section eaves beam	any	b
117	Cold formed C-Plus section	any	b
118	Cold formed ZED section	any	b
119	Cold formed ZED section asymmetric lips	any	b
120	Cold formed ZED section inclined lip	any	b
121	Cold formed Sigma section	any	b
122	Cold formed Sigma section stiffened	any	b
123	Cold formed Sigma-Plus section	any	b
124	Cold formed Sigma section eaves beam	any	b
125	Cold formed Sigma-Plus section eaves beam	any	b
126	Cold formed ZED section both lips inclined	any	b
127	Cold formed I-Plus section	y-y z-z	a b
128	Cold formed IS-Plus section	y-y z-z	a b
129	Cold formed Sigma section asymmetric	any	b
130	Cold formed 2C section	y-y z-z	a b
	2CFCo with a = 0	y-y z-z	a b
	2CFCc with a = 0	Closed section rule 6.2.2(3)
	2CFUo with a = 0	y-y z-z	a b
	2CFUc with a = 0	Closed section rule 6.2.2(3)
	2CFLT with a = 0	any	c
	Any other section	any	c

All other sections fall in the ‘other cross-section’ case of curve c for any axis.

For the calculation of the buckling length, we refer to chapter ""Annex B: Calculation of buckling ratio""
