    A study of reanalysis procedures applied to the fully stressed design algorithm
    Matthis, Gene Stuart (Virginia Polytechnic Institute and State University, 1983)
    This thesis presents the results of a study of several reanalysis procedures as applied to the fully stressed design of rigid-framed structures. The objective of the research project undertaken was to: (1) provide a literature review presenting state-of-the-art techniques used in reanalysis, (2) introduce two methods of reanalysis which are developed and used in this study, (3) conduct studies to evaluate the feasibility of each of these methods, and (4) present recommendations pertaining to the use of reanalysis methods. The two methods include an exact method (matrix displacement method) and an approximate method, labeled the modified stress method in this paper. The results of several example problems show that the approximate method produces accurate results while reducing the required computer solution time. Finally, a discussion of applications of reanalysis to other phases of structural analysis/design, particularly in the area of structural optimization, is presented in conclusion of this project.
