Question 8(a)
1. A continuous footing is shown in the figure below. Using Terzaghi's ultimate b.c. equation and bearing capacity factors, determine the gross allowable load per unit area (qall) that the footing will carry. Given: y = 112 pcf, c' = 450 psf, ' = 22°, D = 4 ft, B = 3 ft, and F.S. = 3. gall Unit weight of soil y c' $' 2. Repeat problem #1 using the general bearing capacity equation. Use the appropriate assumptions
The allowable settlement for the shown square footing is 2.5 cm. the footing is placed on clay soil with the following properties. Use 4 layers to calculate the consolidation settlement and see if it satisfies the criterion. (footing weight is negligible) Hint: use the following eqation for Aoz (Boussinesq equations) For square foundations: 0.5 Δσ. = P1=1000 KN 2.0 - 1 + 1.5 1 B (2) 1.76 (q - o:) YSat = 20 KN/m³ Y = 18 KN/m³ Cc = 0.1 eo = 0.6
Problem (2.8):The load-settlement data obtained from load test of a square plate of size (1ft) are as shown below. If a square footing of size (7t) settles (0.75 inch), what is the allowable soil pressure of the footing? Consider sandy soil. Load (Tsf) Settlement (inch) 10 0.4 14 0.6 16 0.8 19 1.0 0.1 0.2 0.3
I need the answer as soon as possible
Pls give me correct solution- In a plate load test on a soil, at a particular magnitude of the settlement, it was observed that the bearing pressure beneath the footing is 100 kN/m². The perimeter shear is 25 kN/m². Find the load capacity of a 2 m square footing at the same settlement.
Two footings, one circular and the other strip, are founded on the surface of a purely Cohesionless soil. Diameter of the circular footing and width of strip footing is same. Then, the ratio of ultimate bearing capacity of circular to strip footing is:
Problem #4 At a development site in Cebu, City, a plate-load test was conducted on soil whose properties resemble that of sand. The plate used in this PLT is 62 cm square. The ultimate load per unit are (qu) for the test was found to be 620 kN/m2. What should be the maximum allowable load of a 2.5 m square footing? Use a factor of safety of 3. Answer in N.
Question #3 A total load of 900 kN is uniformly distributed over a rectangular footing of size 3 x 2 m shown in in Fig. 2. Due to the load on this footing, using influence factors determine the vertical stress at a depth of 2.5 m a) Under the corner at point C b) Under the center D. c) If another footing of size 3 x 1 m with a total load of 450 kN is constructed adjoining the previous footing, what is the additional stress at point C at the same depth due to the construction of the second footing? d) Using Newmark's chart, determine the vertical stress due two both footings at a depth of 2.5 m under point E.
