Ani Oturma (Bowles 1987)

Se=qω(aβ′)1−μs2Es⋅Is⋅If S_e = q_\omega (a\beta') \frac{1 - \mu_s^2}{E_s} \cdot I_s \cdot I_f

IS=F1+1−2μ1−μF2 I_S = F_1 + \frac{1 - 2\mu}{1 - \mu} F_2

F1=1π(A0+A1) F_1 = \frac{1}{\pi}(A_0 + A_1)

F2=n′2πtan⁡−1A2 F_2 = \frac {n'}{2\pi} \tan^{-1} A_2

A0=m′ln⁡((1+m2+1)m2+n2m′(1+m2+n2+1)) A_0 = m' \ln\left(\frac{(1+\sqrt{m^2 + 1}) \sqrt{m^2 + n^2}}{m'(1+\sqrt{m^2 + n^2 + 1})}\right)

A1=ln⁡((1+m2+1)1+n2m′+m2+n2+1) A_1 = \ln\left(\frac{(1+\sqrt{m^2 + 1}) \sqrt{1+n^2}}{m' + \sqrt{m^2 + n^2 + 1}}\right)

A2=m′n′m2+n2+1 A_2 = \frac{m'}{n' \sqrt{m^2 + n^2 + 1}}

Df=0ic\cinl=If=f(DfB,μ,LB) D_f = 0 \quad için \quad l = I_f = f\left(\frac{D_f}{B}, \mu, \frac{L}{B}\right)

α = Yerleşimin hesaplandığı temeldeki konuma bağlı faktör

Merkezin altındaki oturma için

α=4,m′=LB,n′=HB2\alpha = 4, m' = \frac{L}{B}, n'=\frac{H}{\frac{B}{2}}

köşenin altındaki oturum için

α=1,m′=LB,n′=HBα = 1, m' = \frac{L}{B}, n' = \frac{H}{B}
