If the length of a wall on either side of a lintel opening is at least half of its effective span L, the load W carried by the lintel is equivalent to the weight of brickwork contained in an equilateral triangle, producing a maximum bending moment

RCC stands for Reinforced Concrete Cement. In a RCC framed structure, the load of the building structure is transferred from slabs to beams, then to the columns and lower columns, and eventually to the foundation. The design of any reinforced concrete structure starts with the understanding and behaviour of the structure to be designed under load.
