Abstract
Millions of reinforced concrete structures are being constructed every year throughout the world. Almost all the designers are not able to adopt economical aspects related to the design that may result in lots of saving in materials and cost because, at present, factors to be considered for economical solutions are not available. Hence, in this theoretical investigation an attempt has been made to study the influence of the important parameters in the economical design, of some of the RC members and structures. At first, influence of grades of concrete and steel on the economical design of axially loaded RC tension and compression members has been studied. In addition to the influence of grades of the constituent materials, the percentage of steel has also been considered to arrive at the economical design of RC short columns subjected to axial load and biaxial bending moments
