Abstract

Optimal design of reinforced concrete frames N.C. Das Gupta, V. Thevendran, G.H. Tan Department of Civil Engineering, National University of Singapore, 10 Kent Ridge Crescent, 0511 Singapore ABSTRACT The paper considers the minimum cost design of reinforced concrete frames in accordance with the British standard code of practice, BS8110. Cost in this study includes the cost of concrete, reinforcement and formwork. Design and practical constructional requirements are formulated as optimization constraints. A simple and effective procedure to solve the resulting nonlinear constrained minimization problem is presented. The nonlinear minimization problem has been solved numerically using direct search methods in a microcomputer. INTRODUCTION Study in the field of structural optimization has received considerable attention with the advances made in optimization algorithms and computer technology. Krishnamurthi and Munro [1] formulated the problem a
