Reliability based structural analysis and optimization in X window environment

A graphic-based application in X window environment using Open Software Foundation (OSF)'s Motif toolkit is developed for comprehensive reliability based analysis and design of structures. The application is interfaced with an efficient safety index calculation code for conducting probabilistic analysis of structures for different performance functions using statistical data of random variables. It is also integrated with a reliability based optimization code for obtaining an optimum set of design parameters by determining analytical sensitivities and constructing approximations for the reliability constraint. The graphic user-interface includes interface with external graphic packages along with Motif window-widget layout to enhance visual perceiving capabilities and interpretational facilities. Probability analysis and design of turbine blades and frame structures with multidisciplinary requirements were addressed during the development of the analysis and design codes.
