Object-oriented parallel second-order inelastic analysis of frames
Abstract
This research is directed toward the second-order inelastic analysis of frames using high performance computing environments. This work integrates parallel computing, object-oriented design, and computer graphics for the inelastic analysis of framed structures. A beam-column element that captures second-order (geometric nonlinear) and distributed plasticity effects with improved accuracy and efficiency relative to conventional displacement-based formulations is developed. The formulation of the element is based on mixed method and co-rotational total Lagrangian approach. In order to take advantage of parallel processing for handling computationally intensive second-order inelastic analysis, a parallel finite element framework, PFE++ is developed. To facilitate the visualization of analysis responses, an object-oriented Graphical User Interface, MUIApp (Motif User Interface Application) Framework is developed and combined with a graphics application framework. An object-oriented approach has been chosen in the design and implementation of the aforementioned software in order to facilitate extensibility, reusability, maintainability and simplicity. The proposed research is part of a major effort underway at Purdue University on the development of an object-oriented concurrent software development environment for structural engineering. The proposed research should help in the realization of second-order inelastic analysis of large structural systems in research and practice, resulting in more realistic and rational analysis and design of framed structures.
