Computer-Aided Structural Design Optimization Using a Database Management System.
Abstract
A study was made to integrate finite element-based-optimal structural design methods and computer-science methods into a computer-based system containing a a database, a program library and man-machine communication link. Emphasis is placed upon database management concepts for structural design. Important components required to build a computer-aided structural design system are described. A number of database management concepts -- hieracrchical, network and relational data models, conceptual, internal and external view of data organization, normalization of data, and global and local database are discusses with reference to structural design data. A methodology to design a database is proposed. Three levels of data organization-conceptual, internal and external are suggested. A methodology to construct a numerical data model is described. This model supports data of various types of large matrices such as banded, skyline and hypermatrices. Requirements of database management system and components needed to develop it are discussed. Language requirements to enable good communication link between designer and computer are formulated. A database management system - MIDAS is implemented for use in structural design applications.
