Reinforced concrete framework design optimization H. Mohan-ami, D.E. Grierson Department of Civil Engineering, University of Waterloo, Waterloo, Ontario, N2L 3G1 Canada ABSTRACT This paper presents an efficient computer-based method for the optimal design of reinforced concrete building frameworks. The width, depth and longitudinal reinforcement of member sections are taken as the design variables. An Optimality Criteria method is applied to minimize the cost of concrete, steel and formwork subject to constraints on strength and stiffness. Two reinforced concrete framework examples are presented to illustrate the features of the design optimization method. INTRODUCTION Many studies can be found in the structural optimization literature that have focused on reinforced concrete structures. Most studies have been concerned with the optimization of cross-section dimensions of standard reinforced concrete members used in prefabricated construction, e.g., [1]. A f
