Reinforcing steel has excellent strength in both compression and tension loads but is more expensive than concrete. Therefore reinforced concrete structures are typically designed by engineers such that concrete is mainly utilized for most of the compressive forces and reinforcing steel is utilized for all of the tensile forces and in some cases some of the compressive forces. The design of reinforced concrete structures has been streamlined particularly over the last century for safety as well as economic feasibility.
