Annotation:
Image NB 3.1. - Values description and symbol convention during loading by Fz
(C) - compression fibers, (T) - tension fibers, S - shear center, G - center of gravity
Image NB 3.2. - Symetric cross sections - symetric to center or to the stiff axis
Table NB 3.1. - Coefficient values C1 and C3 when member is loaded by end moments dependent on coefficients kz and coefficients yf and kwt
remark 1)
remark 2) 0,7L = fixed left end, 0,7R = fixed right end
Table NB 3.2. - Coefficient values C1, C2 and C3 for different cases of perpendicular loading, dependend on coefficients ky, kz, kw and coefficients yf and kwt
remark 1)
remark 2) Parameter ψf is for the center of the length
remark 3) Values of critical moment Mcr is for the section with Mmax
