Reinforced or Ferro Concrete is a combination of Concrete reinforced with steel bars in such a manner that the steel, (1) Takes all the tensile forces in the combination, (2) Helps the concrete in the resistance of shear and compression where necessary. The idea of reinforcing concrete with metal is not a new one. Such early engineers as the Romans leave us examples of this method of construction, but it is doubtful whether they had much knowledge of the mechanics involved in the design, although they most certainly had some idea of the fundamental principle, that is to reinforce the concrete where it is weakest, viz., in the tensile regions. Their materials, however, were very crude, Portland Cement and Steel being unknown. With the advent of the cheap manufacture of Portland Cement and Steel, along with the awakening of engineers to the possibilities of Reinforced Concrete, and the untiring energy of the pioneers of this construction during the latter part of the last and the beginning of this century, Reinforced Concrete has become one of the leading, it not the leading method of construction throughout the world. It is used for all types of construction, such as Buildings, Brid
