Team Management

To complete a specific task or to accomplish organizational goals along with increasing work productivity, individuals need to come together and think along a common path and direction. There are certain tasks in an organization that cannot be done alone and the involvement of more individuals is essential. These groups of individuals who work together for a common goal compose a team and the individual members involved are known as team members.

Redo Problem 18.10 using the method for estimating the skin resistance. 18.10 A concrete pile 15 m long with a cross section of 380 mm 380 mm is fully embedded in a saturated clay layer. For the clay, sat = 18 kN/m3, = 0, and cu = 80 kN/m2. Assume that the water table lies below the tip of the pile. Determine the allowable load that the pile can carry (FS = 3). Use the a method to estimate the skin resistance.
Consider a 500 mm diameter pile having a length of 18 m in a clay. Given: γ = 20.0 kN/m3 and cu = 60 kN/m2. Determine the maximum allowable load (Qall) with FS = 3. Use the α method and Table 12.11 for determining the skin friction and Eq. (12.20) for determining the point load. Allow a factor of safety of 3. What percentage of the ultimate load is being carried by the pile shaft? Is it a friction pile?
