Abstract: GTSTRUDL is the one of five softwave appraised by Atomic Energy Commission of America. Recently, it have been accepted gradually by structural engineers in the world, and used widely in the structural analysis and design process. Therefore, mastering and developing GTSTRUDL have important practical value. This paper introduce the graphical function of this computer aided structural engineering software system developed by Georgia Institute of Technology of U. S. A. The ingredients of graphical function of GTSTRUDL, its managerment, structure, and method of use are presented here. The example and the operational steps given in this paper may be a miniature of graphical function of GTSTRUDL. It have important reference value for engineers and technicians to master and use graphicdl function of GTSTRUDL.
