$N_{60,\text{corrected}} = 15 + 0.5 \left( N_{60} - 15 \right)$

$l_c = \frac{1.71}{N_{60}^{1.4}}$

$\delta_{\text{footing}} = \left( q_{\text{net}} - \frac{2}{3} \sigma'_p \right) \cdot \frac{1.71}{N_{60}^{1.4}} \cdot \beta^{0.7}$

$f_q > \sigma'_r$

$f_s = \left( \frac{\frac{1,25L}{\beta}}{0.25 + \frac{L}{\beta}} \right)^2$

$f_1 = \frac{H_z}{s_1} \left( 2 - \frac{H_z}{s_l} \right)$

$f_t = 1 + R_3 + R_t \cdot \log\frac{\tau'}{3}$
