Object-Oriented Modeling of Structural Analysis and Design with Application to Damping Device Configuration

Abstract

This paper presents an object-oriented (OO) software framework for computer-aided structural analysis and design research, where different structural analysis methods and design procedures need to be implemented and investigated. The framework is designed with four basic modules: structure, load, analysis, and design. Each module includes a set of cooperating interfaces and classes. Through the predefined interfaces, the framework provides architecture for many structural design applications. A variety of similar entities, such as different design applications, design procedures, and analysis methods, can be built on this architecture by implementing the necessary interfaces. The clearly defined interactions between the modules accommodate the future extensions within the modules. The final OO design of the framework can be communicated by many well-known design patterns, and it is described by unified modeling language. The framework is then customized to the application for optimizing the configuration of energy dissipation devices in a given structure. By implementing a few interfaces, this paper illustrates how this OO framework accommodates changes, and how reusability and extensibility can be achieved.
