This paper focuses on optimal design of reinforced concrete structures when a great number of load combinations are allowed for. An improved method of finding significant load combinations out of a great number of possible load combinations is proposed and implemented in programs of optimal design for reinforced concrete structures. This study presents a numerical example of optimal design of a frame using continuous and discrete approaches. We conclude that the traditional method of finding significant load combinations ignores one significant load combination, which leads to decreasing the amount of enforcement. However, the improved method has provided correct results.
