A study was performed to verify the accuracy of the Intergraph MicasPlus structural analysis and design software and to evaluate its functionality. The components of MicasPlus to be considered in the study include linear static analysis and steel design and code checking in accordance with the AISC Allowable Stress Design specifications. The verification is based on a comparison of results obtained using the MicasPlus and GTSTRUDL programs for three dimensional steel structures. The factors to be considered in the comparison include support reactions, member forces, displacements, ratios of applied stresses to allowable stresses, and member sizes. The factors to be considered in the evaluation of the functionality of the program include the ease of modeling, amount of effort required to enter the structural models and loads, potential for user errors, quality of support and documentation, and format and quality of the final output. / Master of Science
