Microcomputers and Design Codes: A Case Studyby Paul C. Hoffman, Villanova Univ, Villanova, PA, USA,
Abstract: A microcomputer analysis of the thermal stress problem in reinforced concrete box sections was conducted. An explicit finite difference algorithm for a one-dimensional heat flow analysis was programmed on a microcomputer. A commercial software graphics package, Grafmatic, was utilized. The findings indicated that the microcomputer has a substantial computational capacity for thermal stress analysis of bridge superstructures. The programming approach is readily extended to a two-dimensional thermal analysis. The implication of the study is that design codes need to address the free and ready access afforded by the personal computer.
