T-Section Concrete Beam Design Case-1

If the moment strength, as calculated on the previous sheet, is larger than ultimate moment, case-1 is used, that means the depth of the compression block is less than the flange (slab) thickness. in the chart, the required area of flexural reinforcement is also calculated.
