Abstract
A study was performed to verify the accuracy and evaluate the
functionality of two structural analysis and design programs.
The programs that were studied were MicasPlus and
GTSTRUDL. The components of the programs considered in
the study included linear static analysis, steel design, and code
checking in accordance with the AISC Allowable Stress
Design specification. The verification was based on a comparison
of results obtained for several existing three dimensional
steel structures. Factors considered in the comparison
included support reactions, member forces, displacements,
ratios of applied stresses to allowable stresses, and member
sizes. The factors considered in the evaluation of the functionality
of the programs included ease of use, amount of effort
required to enter the structural model and loads, potential for
user errors, quality of support and documentation, and format
and quality of the final output.
