CSTRUCT: An Interactive Computer Environment for the Design and Analysis of Earthquake Resistant Steel Structures

摘要

The purpose of the report is to describe progress on the development of a new computer-aided design package called CSTRUCT for the analysis and design of earthquake resistant steel frames. Its implementation is for 32-bit engineering workstations with bit-mapped high resolution graphics capable of operation under Ultrix, and the X-Window System. Software development issues such as the user interface, management of data, and the choice of a computer language are covered. As the problem description evolves, the frame and optimization attributes are identified, and employed by the user in the ensuing design process. The use of the command language and the graphical tools to identify attributes of the optimization problem, critical frame actions, frame displacements under different loadings, and to determine the overall adequacy of a design is shown. Software implementation is summarized and suggested directions for continued software development are listed.
