Abstract

A synergic man-machine approach is presented for performing practical shape optimization of bridge trusses. Design constraints are the allowable tensile and compressive stresses, slenderness limits, allowable stress range in fatigue and displacement and fabricational constraints. The moving loads acting on the bridge and the design constraints are based on the American Association of State Highway and Transportation (AASHTO) specifications. The synergic man-machine approach to shape optimization is based on changing the key layout parameters of the bridge truss (that is, the height and the number of panels) and performing optimization for each layout in an interactive computer graphics environment. The method is applied to four types of steel bridge trusses, i.e., Pratt, Parker, parallel-chord K truss, and curved-chord K truss for a span range of 100 - 500 ft.
