The ratio of steel to concrete is 100:130 for 1 cubic meter. The ratio means that for every 130 kg of concrete, 100 kg of steel is needed to support the structure. This is a rule of thumb in civil engineering that must be observed at all times, as failure to observe it renders buildings prone to ductility and cracking.

A load applied to the top of the books would require an even greater force to be applied to prevent collapse. In reinforced concrete, the steel reinforcement carries all of the tensile stresses and, in some cases, even some of the compressive stresses. In prestressed concrete, the tendons are used primarily to keep the concrete in compression.
