This video gives you detail steps how to design a cantilever beam as per IS 456-2000. Cantilever beam is one which is fixed at one end and other end is free of support.
In cantilever beam Tension Zone is at the top side so main bars should be placed on top side that is in tension zone. Detailed explanation has been given so watch this video completely to gain full concepts of how to design a RCC Cantilever Beam according to IS 456-2000.
PLEASE NOTE : Dear viewers please note that there is slight mistake at 18:23 i have taken 0.133 which is valid for Fe500 instead of 0.138 for Fe415, please make note about it that it should be 0.138. Therefore effective depth will become 337mm instead of 343mm

Hi sir, really loving all your videos. Could you please clear one of the practical doubt of the following case. It is for my home site. How do I extend a balcony of 1.2x2.5m of a preconstructed apartment using cantilever beams? It is a third floor. Column size is 9x12 inches. I am going to use 6 top bars of 16 mm and 3 bottom bars of 16mm, curtailing 2 top bars at 0.6m with the main slab bars of 12mm and distribution bars of 10mm. Stirrups bar of 8mm with spacing 4 inches center to center. cover block of 30mm with hook angle 135 degrees and angling downwards. slab thickness at support 6 inches As it is preconstructed apartment, I could not extend the bar back, however I have reclaimed around 0.6m beam and slab bars after demolishing beam and slab. Will this be enough for lapping length of slab and development length of cantilever beam. I plan to create a brick wall (4 inches, 9 feet ceiling height) to include this space inside to be used as a kitchen counter of 2 feet and overhead storage. What modifications I can perform to ensure safety. Total reinforcement area is now 3feet 6 inches cantilever, column(9″x12″), 2feet overlapping length.

So that the students will understand why it is a cantelever. Why it is starting from column. Tell how the load is coming. Shiw full details then come to the xantelever
