Description

This Data Item presents form factors for use in calculating the maximum permissible bending moments for sections that are NOT symmetrical about the axis of bending. For sections such as T- and channel-sections, the maximum permissible bending moment is reduced by the application of the axial load when that load acts so as to cause failure of the outstanding leg. This Data Item applies strictly to the case where the end load acts in a direction such as to cause failure of the outstanding leg. If the end load acts in the opposite sense the form factor is slightly greater than the value given by this Data Item and, in that case, ESDU 90004 and its computer program can be used to obtain more accurate results. The form factors in this Data Item incorporate the Ramberg-Osgood formula to define the stress-strain curve of the material.
