✦ Synopsis
A microcomputer-aided design (MicroCAD) system has been developed for interactive design of connections in steel buildings made of standard roiled I-sections, called Steelcon. Design of different connections is based on the American Institute of Steel Construction specification. Connecting elements may be plate& angles, or T-section~ Connectors may be bolts or weld& The MicroCAD system can display/plot any isometric view of the connection plus the orthographic views, i.e. front, side, and top views. The application of the MtcroCAD system to the design of simple (type 2) shop-welded and field-bolted beam-column angle and plate connections is discussed. Microcomputer graphics for displaying the isometric and orthographic views including the dimensions and designations are presented. This Micro-CA D system can be used effectively for practical design of connections in steel buildings. microcomputer& computer-aided design, beam-column connectlon.
This paper presents interactive design of connections in steel buildings on microcomputers. The authors are in the process of developing a user-friendly interactive MicroCAD system for design of beam-column connections in steel buildings, called Steelcon. In addition to designing the connections, the microcomputer program can display/plot any isometric views and three orthographic views (front face, side face, and top face views) of the connection. The program structure and graphic algorithms are presented in Adeli and Fiedorek I . This paper presents application of the MicroCAD system Steelcon for design of shop-welded and field-bolted beam-column connections. Design of different types of connections is based on the American Institute of Steel Construction (AISC) specification 2. Under no circumstances does the program violate the above specification, or allow the designer to enter data in violation of the AISC code. The interactive design approach has been the subject of a number of recent articles by Adeli and coworkers 3-s. In this approach, the user/designer is in charge and the CAD system works as an assistant to him/her.
The program allows the user/designer to correct his/her mistakes without causing the program to terminate or do any other undesirable action. Every time the user is prompted to input something, a check is made to see if the data input is within the permissible range. Some of the prompts to the user require a yes or no answer. For this type of prompt, if the user types either 'y' or 'Y' the answer
