Reinforced Cement Concrete Lintels

Reinforced cement concrete lintels are the most general used these days. They have replaced all other kinds of lintels since of their rigidity, strength, fire resistance, economy and ease in construction. These could be used on any span. Its width is remaining equal to the width of the wall. The depth of RCC lintel and the reinforcement depends upon the span and the magnitude of loading. Longitudinal reinforcement, consisting of mild steel bars is given near the bottom of lintel to take up tensile stresses. Half these bars are thus cranked up near the ends. Shear stirrups are given to resist transverse shear. A typical RCC lintel is display in Figure 6 RCC lintel over a window. Formwork is needed for construction of cast in-situ lintels. RCC lintels are also available as pre-cast units.
