MasterFrame Analysis Results

The MasterFrame analysis involves the manipulation of the stiffness matrix associated with the analytic structure and the subsequent solution of the system of equations represented by the matrix equation F = K d. From the solution of the system of equations, the deformation of the structure is determined, from which the end rotations of the members are determined. From this the end moments of the analytic members are calculated. Finally, from the end moments and the loading conditions, the resulting bending moments, shear forces, rotations and deflections of the members are calculated.

The results of the analysis can then be displayed, either in numerical format or in a graphical former. Results can be viewed on screen or printed or exported.

Results such as bending moment, shear force, axial force or torsion are displayed relative to the member local axes.

In general, deflections are given relative to the global axes. This relates to the deflection of the nodes in the model.

For members modelling structural elements such as beams, the deflection of the members along its length is generally an important consideration in the design of the structural element. The in-span deflection of the member can be shown in the results outputs. However, since there may be deflections of the nodes at the end of the member, and to account for the orientation of the member itself, the in-span deflection is calculated as the maximum deflection along the member relative to the member axes. Thus, the deflection is taken relative to a straight line between the start and end nodes of the member.
