1) Balanced: Concrete crushed and steel yields simultaneously at the ultimate limit state. The compressive strain of concrete reaches the ultimate strains ε cu and the tensile strain of steel reaches the yield strain ε y simultaneously. The depth of neutral axis, x = 0.617d. 2) Under-reinforced: Steel reinforcement yields before concrete crushes.
The first use of iron-reinforced concrete was by the French builder François Coignet in Paris in the 1850s. Coignet's own all-concrete house in Paris (1862), the roofs and floors reinforced with small wrought-iron I beams, still stands. But reinforced concrete development began with the…

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...
Reinforced Concrete. ... (concrete) that resists compression and a material (iron or steel) that resists tension. It is also considered fireproof and dimensionally stable. However, all these materials take energy and resources to make. Like concrete, the steel reinforced version can be recycled by crushing it and removing the steel bits with ...

Reinforced concrete permitted the development of an entirety new building form-the thin shell. In 1930 Eduardo Torroja, the brilliant Spanish engineer, designed a low-rise dome of 3.5-in thickness and 150-ft span for the market at Algeciras, using steel cables for a tension ring.
Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. Conven-tional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust. Aggregates must conform to certain standards for
François Coignet was the first to use iron-reinforced concrete as a technique for constructing building structures. In 1853, Coignet built the first iron reinforced concrete structure, a four-story house at 72 rue Charles Michels in the suburbs of Paris. Coignet's descriptions of reinforcing concrete suggests that he did not do it for means of adding strength to the concrete but for keeping ...

Several reinforced concrete (RC) structures fail via concrete crushing in compressed zones. This is the case, for instance, of over-reinforced concrete beams, like in the four point bending tested by Mansur et al. [1]. When fiber-reinforced, the post-peak behaviour of such members is remarkably more ductile than that observed in beams having ...
