Optimal design of Schwedler and ribbed domes via hybrid Big Bang-Big Crunch algorithm
Volume 66, Issue 3, March 2010, Pages 412-419, Journal of Constructional Steel Research
Kaveh, A. | Talatahari, S. 
An optimum topology design algorithm based on the hybrid Big Bang-Big Crunch optimization (HBB-BC) method is developed for the Schwedler and ribbed domes. A simple procedure is defined to determine the Schwedler and ribbed dome configuration. This procedure includes calculating the joint coordinates and element constructions. The nonlinear response of the dome is considered during the optimization process. The effect of diagonal members on the results is investigated and the optimum results of Schwedler domes obtained by the HBB-BC method demonstrate the efficiency of these domes to cover large areas without intermediate supports. © 2009 Elsevier Ltd.

Charged system search for optimum grillage system design using the LRFD-AISC code
Volume 66, Issue 6, June 2010, Pages 767-771, Journal of Constructional Steel Research
Kaveh, A. | Talatahari, S.
Grillage systems are widely used in structures to cover large areas in bridge decks, ship hulls and floors. In this paper, the charged system search (CSS) algorithm is utilized to obtain the optimum design of grillage systems. This algorithm is inspired by the Coulomb and Gauss laws of electrostatics in physics and the governing laws of motion from Newtonian mechanics. The cross-sectional properties of beams are considered as the design variables. Comparison of the results with those of some previous studies shows the robustness of the new algorithm. © 2010 Elsevier Ltd. All rights reserved
