Only first part (i) please.
Consider the strip footing shown in the figure below. The soil consists of sand with f’ =36° and c’=0 kPa and γsat = 21 kN/m3. (Assume the footing to be very long). Calculate the ultimate bearing capacity of the foundation in kPa a long time after construction using the modified bearing capacity equation
5A strip footing was constructed on a pure sand which is 1.5 m wide with its base at a depth of 1 m. Using Terzaghi's method, the ultimate bearing capacity of strip footing will be [Take Y₁ = 16 kN/m³, N = 75, Assume general shear failure] 1 (a) 1876 kN/m² (b) 1860 kN/m² (d) 1792 kN/m² (c) 1788 kN/m²
SHOW ME A DETAIL SOLUTIONS FOR THIS PROBLEM. A 2.90 meter square isolated footing with thickness of 650 mm is to carry a concentric load of 1200 kN service dead load and 1120 kN service live load. The bottom of the footing is rested at a depth of 1.50 m from the ground surface. The ultimate bearing capacity of the soil is 775 kPa, with recommended factor of safety of 2.50 for design. The footing has a bottom reinforcement of 17 pieces of 16mm diameter bars on both directions. Use f'c = 29.25 MPa and fy = 275 MPa. Use clear concrete cover of 75 mm. Assess the adequacy of the design of the said footing to carry the given loads. Neglect the effect of soil at top of footing and weight of footing on net bearing capacity of soil.
Please answer it ASAP for an upvote. Thank you. Given that the cohesion in the soil is 16 kPa and the angle of internal friction is 22 degrees, what is the gross ultimate bearing capacity (kPa) of the continuous footing with a width of 2.5 m. Assume γsoil = 17.40 kN/m3, γsat = 20.43 kN/m3. The depth of the foundation is at 1.50m and the GWT is at 2.21m. The load is inclined 0 degrees with respect to the vertical.
Q2: For the following spread footing, calculated the width of the footing if the footing length is 3.0m and the allowable bearing capacity was 126 kPa. 2a kN 33 kN. m 6 30 kN 1.5 n
Question 2: For the footing given below, calculate the ultimate bearing capacity (qu or qf) and net ultimate bearing capacity (4nf) of the footing given below using General Bearing Capacity Equation. General shear failure occurs in the soil and the relevant information are given below. There is no ground water level. It has been observed that resultant load acting on the footing is vertical. However, resultant load creates an eccentricity (only one-way eccentricity), therefore, a moment. The eccentricity is e = 0.5 m D, = 3 m 6m * 6m Soil c' = 3 kPa o' = 30° Ym = 19 kN/m³3 Center Line
Consider the strip footing shown in the figure below. The soil is a clay-dominant material with f’=26° and c’=3 kPa, Su = 70 kPa and γsat = 21 kN/m3. (Assume the footing to be very long). Calculate the ultimate bearing capacity of the foundation in kPa shortly after construction using the modified bearing capacity equation
