3. NATURE OF PHYSICAL PROBLEM SOLVED
The programme is intended to analyse almost any type of spaceframe. Members of the frame may be either straight or of constant curvature between nodes provided that, in the case of curved members, one of the principal axes of the cross-section of the member lies in the same plane as the member. Loading may comprise concentrated loads, distributed loads, thermal loads or may take the form of specified displacements.
The programme calculates the forces and moments in all the members of the framework, the reactions at all external restraints and the displacements of all the nodes. For pipework problems, the maximum stress difference in the pipe, calculated in accordance with the code of practice, is also quoted.
