1.8Convention for Member Axes

Unless otherwise specified convention used for member axes is as follows (see Fig. 1):

• a) $x-x$ along the member
• b) y-y an axis of the cross-section.

1. perpendicular to the flanges, and
2. perpendicular to the smaller leg in an angle section.

• c) z-z an axis of the cross-sectio

1. axis parallel to flanges, and
2. axis parallel to smaller leg in angle section.

• d) $u-u$ major axis (when it does not coincide with $z-z$ axis).
• e) v-v minor axis (when it does not coincide with y-y axis).
