Reinforcing bars are quite expensive, and thus the percentage of longitudinal reinforcing used in reinforced concrete columns is a major factor in their total costs. This means that under normal circumstances a small percentage of steel should be used (perhaps in the range of 1.5 to 3%). This can be accomplished by using larger column sizes and/or higher strength concretes. Furthermore, if the percentage of bars is kept in approximately this range, it will be found . Structural steel has high yield strength and ultimate strength compared with other construction materials.
