title = "Prediction of minimum weight design of 3D steel frame structure from decomposition into 2D frames",
abstract = "This paper presents a prediction method of minimum weight design of a 3D steel frame structure by decomposition into and composition from 2D frames. An optimum design problem is set up as a minimum weight design problem whose design variables takes the cross-sectional dimensions. We investigate the influence of the constraints of cross-sectional dimensions to minimum structural volume and the initial value dependences by random multi-start method. From the results of numerical examples, we can decrease dispersion of the solutions by the approach and hence we can improve predictability of the solutions. Finally, we show that the decomposition into 2D frames and composition from optimum solutions have a good correspondence to the optimum solution of 3D frame under certain conditions.",
