Jse Terzaghi's bearing capacity equation to determine the allowable load capacity, \( P_{\text {all }} \) of a trip footing, and using the following data: Note: \( \boldsymbol{P}_{\text {all }}=\frac{Q_{U} \times A}{F S} \), where: \( \mathrm{A} \) is the area of the footing, FS is the Factor of Safety, FS \( =3 \) The soil is clay with soil cohesion, \( C=2.0 \mathrm{kpa} \) Length of strip footing \( \mathrm{L}=14 \mathrm{~m} \) Soil friction angle, \( \phi=22^{\circ} \) Soil unit weight, \( \gamma=18 \mathrm{kN} / \mathrm{m}^{3} \) The width of the footing, \( \mathrm{B}=1200 \mathrm{~mm} \) And the depth of the footing, \( D_{f}=900 \mathrm{~mm} \) \[ Q_{u}=C N_{C}+q N_{q}+0.5 B \gamma N_{\gamma} \] Terzaghi's bearing capacity equation Where: \[ q=\gamma D_{f} \]
