1-To couteract the maximum shear stress developped at support
2-the Maximum shear stress zone in a column exists at the distance of l/3 from junctons of column with beam / slab ,so in this zone more stirrups are required to be provided,
3-at the ends of the beams, maximum hogging moment zone exists which causes column for faliure at top layer. this is why extra bars at the ends/ junctions of beams ,in top layer are provided.
4-o/lap length is the length of bar which is provided in the rienforcement where two bars are jointed linearly
lap length is the minimum specified length required for overlapping of two bars. its length is fixed for various grades of concretes.
5-The minimum length of bar required for the development of perfect bonding with concrete at the ends is called development length .it is calculated by Qst/4.tou.b.d

5. Two long boundary walls run parallel to each other at a center to center distance of 1 meter apart. The width and height of the first wall are 0.30 m and 2.5m respectively. While those of the second are respectively 0.18m and 3.5m. Plot the distribution of vertical stress intensity due to walls on a horizontal plane, 1m below ground level. The walls have negligible depth of foundation and are made of brick masonry (y = 19.2 kN/m cu)
