Extensive experimental studies indicate that the lateral deformation of RC columns consists of deformations induced by flexural, bond-slip, and shear effects.

In 1890, Ransome built the Leland Stanford Jr. Museum in San Francisco, a reinforced concrete building two stories high and 312ft (95m) long. Since that time, development of reinforced concrete in the United States has been rapid. Ernest L. Ransome System.

Concrete is a composite building material made from a mixture of sand, gravel, crushed rock, or other aggregates (coarse and fine) held together in a stone like mass with a binder such as cement and water. The stone like mass is formed due to the hydration of cement and eventually due to its hardening.
