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.
