Graphics based preliminary structural design Mary Lou. Maher Weiguang Zhang Carnegie Mellon University.Engineering Design Research Center. 10.1184/R1/6466331.v1 https://kilthub.cmu.edu/articles/journal_contribution/Graphics_based_preliminary_structural_design/6466331 Abstract: "The development of graphic based preliminary design programs is appealing because preliminary design involves the consideration of alternatives as concepts or sketches. The use of such a program would allow engineering students and new graduates to gain experience directly, through their own trial and error. This paper describes a graph based preliminary design program that was developed to facilitate teaching architect and engineering students about structural design." 1986-01-01 00:00:00 Structural design.
