If l_{1} and l_{2} are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w_{1} and w_{2} acting on strips parallel to l_{2} and l_{1} is

If L is the effective span of a R.C.C. beam which is subjected to maximum shear q_{max} at the ends, the distance from either end over which stirrups for the shear, are provided, is
