Unfortunately, there are mistakes in Eq. (19). The corrected equation is given here:

$$\xi = 1.5\frac{{E \cdot h \cdot \overline{{F_{y} }} }}{{\overline{K} \cdot L^{2} \cdot f_{y} }} \cdot \left( {\sqrt {1 + 5.33 \cdot (i/h)^{2} \cdot \frac{{\overline{K} \cdot L}}{E} \cdot \frac{{f_{y} }}{{\overline{{F_{y} }} }}} } \right)$$
