Abstract
The optimal design of reinforced concrete frames is considered by treating the various design parameters. The brief contents of the study are as follows : 1) The mathematical non-linear programing technique is applied for the formulation of optimization of reinforced concrete frames. The non-linear optimization problem is solved by the sequental unconstrained minization technique (SUMT), and the unconstrained problem is opitimzed by Davidon-Fletcher-Powell method. 2) In order to solve the optimization problem of large-size structures such as multistory frames, the substructure method is applied. The structure is partitioned into several substructures, and then, each substructure is optimized in turn from the top story down to the bottom story. Repeating this procedure, the overall solution of the structure is obtained sequentialy. 3) The minimum weight design of two types of reinforced concrete frames that are subjected to static loads are carried out, and the obtained results are discussed.
