Secondary voltage

In technical mechanics , ancillary stresses are understood to mean stresses within a framework that additionally z. B. due to the elastic bending deformation of the framework bars to the stresses of the ideal framework according to the framework theory . Under certain conditions, the secondary voltages can assume considerable values. In the case of level trusses, the secondary stresses also include the stresses caused by loads perpendicular to the plane of the truss, for example from wind loads. Ancillary stresses take on considerable values ​​in particular when the truss bars are not very slim.
