Example Description

This example tests distributed and concentrated moments assigned to frame objects, by applying torsional moments on a shaft. In SAP2000, you can apply distributed (uniform, trapezoidal and triangular) and concentrated moments to frame objects.
In this example a 1-inch-diameter circular shaft, fixed at one end, is loaded with various types of torsional moments in two different load cases. The resulting torsional reaction at the fixed end and the rotation at two joints along the shaft are compared with independent, hand calculated results.
