"WebMembers of a structural system are typically oriented in differing directions, e.g., Fig. 17.1. In order to perform an analysis, the ele-ment stiffness equations need to be expressed in a common coor-dinate system – typically the global coordinate system. Once the element equations are expressed in a common coordinate system, " - Member force in the element coordinate system
