- Piles are needed to support columns in a high rise building at a particular site. The probability of failure of a pile due to excessive axial load is estimated to be 10 Suppose that four soch piles are required under each colunas and there are 20 identical columns in the filding Assume that the failure of piles are statistically independent of mach other. (a) What is the probability that none of the piles under a column foundation will fail (b) What is the probability that none of the columns in a building will staffer damage due to p pile failure?What is the ultimate capacity in kN of the pile group shown in the figure assuming the group to fail as a single block? 1.2m cc 0.4m diameter piles Clay soil Cu-40kN/m2 1.2m ocA group of twelve prestressed concrete piles is to support a building column. The total downward design load on the group is 4,900 k. Assuming this load is evenly distributed across the 12 piles, and that there are no moment or shear loads, select a pile size and 28-day compressive strength of the concrete.
- The group efficiency factor for piles in saturated clay is low soon after driving, and increases with time. Why does this occur?c) Several different items are used in the design and construction of piles, including: i) Engineering Analysis ii) Field Load Tests Discuss the above itemsProblem 3: You have been assigned to check the geotechnical capacity of a concrete pile foundation designed by your colleague. The design drawing shows 27m long 600mm diameter concrete piles. The specified end bearing capacity is 3000 kPa (ULS). The total factored ULS load on the pile is 2210 kN. The geotechnical engineer specified the following parameters: End bearing reduction factor =0.95 Skin group reduction factor = 0.9 ULS geotechnical resistance factor = 0.6 Elevation (m) Ultimate unit From То skin friction (КРa) 15 1106 1104.5 1102.5 1104.5 35 Check if the pile has adequate geotechnical capacity. 1102.5 1092 45 1092 1085.5 55 1085.5 1083 70 1083 1080 110 1080 1076 230

Use FS=3.0Estimate the group efficiency of a 4 x 6 pile group, consisting of 400 mm diameter concrete piles at 1.2 m center-to-center spacing using a. the Converse-Labarre equation b. the Los Angeles Group Action equationQ- Find the total load carrying capacity of a group of 9 piles with a group efficiency factor of 0.9. Given that the load carrying capacity of an individual friction pile is 200 kN.
