철근콘크리트보의 최적설계를 위한 비선형계획법의 적용 및 사용자 대화시스템 개발 = Application of Non-Linear Programming and Development of User Interactive System for Optimum Design of Reinforced Concrete Beam

다국어 초록 (Multilingual Abstract)

This paper deals with the minimum-cost design problem of reinforced concrete beam. The total cost of the structure includes the cost of concrete, reinforcing steel and formwork. The minimum-cost design of simply supported beam loaded by distributed load subjects to constraints on strength, serviceability, stability, durability, fire resistance. The minimum-cost design problem is formulated as a non-linear programming(NLP) problem whose solution is attempted by two techniques, namely sequential linear programming(SLP) and sequential convex programming(SCP). Also, minimum-cost design using user interactive system can be easily performed and practice designer and apply optimum design to preliminary design.
