Optimum design of steel frames with semi-rigid connections using Big Bang-Big Crunch method
A. Rafiee, S. Talatahari and A. Hadidi
Abstract
The Big Bang-Big Crunch (BB-BC) optimization algorithm is developed for optimal design of non-linear steel frames with semi-rigid beam-to-column connections. The design algorithm obtains the minimum total cost which comprises total member plus connection costs by selecting suitable sections. Displacement and stress constraints together with the geometry constraints are imposed on the frame in the optimum design procedure. In addition, non-linear analyses considering the <i>P</i>-
