(Architectural Design and Research Institute of Tongji University, Shanghai 200092, China)Abstract: Research on econonucal steel-concrete ratio of concrete beams has important theoretical and practical meanings for economic study of concrete structures. This paper studies a unit length concrete beam, and derives a formula for economical steel-concrete ratio.A numerical analysis of construction cost function is also given.
Keywords: economical steel-concrete ratio; construction cost function
