Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, 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. Probable cause is the time evolving scour and poor inspection. Anchor bolts transfer different types of load: tension forces and shear forces. have discussed in addition to other aspects. 1.

In Post-tensioning, the steel tendons are tensioned after the concrete has been cast and hardened.. Post-tensioning is performed by two main operations: tensioning the steel wires or strands by hydraulic jacks that stretch the strands while bearing against the ends of the member and then replacing the jacks by permanent anchorages that Table 6. 5. Precast cladding or curtain walls are the most common use of precast concrete for building envelopes. (June 21, 2004).

Disadvantages of prestressed concrete: This concrete is high materials cost. Examples of building types. (2) Employers and employees should at all times be aware that the strength of a personal fall arrest system is based on its being attached to an anchoring system which does not reduce the strength of the system (such as a properly dimensioned eye-bolt/snap-hook anchorage). The design of anchorages into concrete is often neglected or short cuts taken because the full design procedure is very rigorous.
