Study on Pre- & Post- Processing Program for Multi -storey & Tall Steel Frame[J]. Journal of Civil and Environmental Engineering, 2007, 29(1): 56-60. DOI: 10.11835/j.issn.1674-4764.2007.01.014.
A vast amount of information data must be input before finite element analysis of steel frames
such as node information
element information and load information. It is necessary to develop a computer aided design system with 3D interactive function. A CAD system for steel frame based on object ARX is developed with AutoCAD API and the Object -oriented technique. In this paper
