MASTAN2: Linear and Nonlinear Matrix Structural Analysis Software

In many ways, MASTAN2 is similar in functionality to today's commercially available structural analysis software. The number of pre- and post-processing options, however, have been limited in order to minimize the amount of time needed for a user to become proficient at its use. The program's linear and nonlinear analysis routines are based on the theoretical and numerical formulations presented in the text Matrix Structural Analysis, 2nd Edition, by McGuire, Gallagher, and Ziemian (John Wiley & Sons, Inc. 2000). In this regard, the reader is strongly encouraged to use this software as a tool for demonstration, reviewing examples, solving problems, and perhaps performing analysis and design studies. Where MASTAN2 has been written in modular format based on MATLAB, the reader is also provided the opportunity to develop and implement additional or alternative analysis routines directly within the program.
Preprocessing options within MASTAN2 include definition of structural geometry, support conditions, applied loads, and element properties. The analysis routines provide the user the opportunity to perform first- or second-order elastic or inelastic analyses of two- or three-dimensional frames and trusses subjected to static loads. Postprocessing capabilities include the interpretation of structural behavior through deformation and force diagrams, printed output, and facilities for plotting response curves.
