PARETO OPTIMA OF REINFORCED CONCRETE FRAMES

Abstract

Optimal design techniques have been extensively appIied to structural design in case of one objectIve iunctIon. They have hardly been used with several objectIve functions. In this paper the multicriterion optimization of reinforced concrete frames is considered and the numerical method for determining the Pareto optimal set of the problem is presented. The criteria to be minimized are the weight of the frame, the volume of reinforcement for the structure and in certain cases the stability criteria. The solution is based on the vector optimization theory.
