If l1 and l2 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 w1 and w2 acting on strips parallel to l2 and l1 is
1
\(\frac{{{w_1}}}{{{w_2}}} = \frac{{{l_2}}}{{{l_1}}}\)
2
\(\frac{{{w_1}}}{{{w_2}}} = {\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^2}\)
3
\(\frac{{{w_1}}}{{{w_2}}}{\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^3}\)
4
\(\frac{{{w_1}}}{{{w_2}}} = {\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^4}\)
