다국어 초록 (Multilingual Abstract)

This study is the formulation of optimum design for reinforced concrete structures with reliability constraints based on the ultimate strength design method. The purpose of this study is to look into the possibility of the detailed and practical optimum design of the reinforced concrete structures. In this study, total cost has been used as the objective function. For the more useful and adoptive to the practical design, the design variables are the overall depth, width, effective depth of members, and area of longitudinal reinforcement. In addition, the details such as the amount of reinforcement and cutoff points of longitudinal reinforcement are also considered as variables. The constraints include the code requirements like the flexural strength, shear strength, ductility, serviceability, concrete cover, spacing, web reinforcement, development length and cutoff points of longitudinal reinforcement.
The optimization algorithm is presented for the effective optimum design of the R.C structures considered the reliability theory and optimization is accomplished by using the Feasible Direction Method. The proposed algorithm was applied to the test problem for reliability, and the results were compared with those of others to examine it's applicability and stability.
