How is pile capacity calculated?
Step 2: compute the ultimate end bearing capacity (acting as individual piles). Ultimate end bearing capacity in clay = Nc × C × pile tip area (Nc = 9). Ultimate end bearing capacity in soft clay = 9 × 120 × π × diameter2/4 = 848.2 lbs/per pile. Total ultimate bearing capacity per pile = 76,920 + 848.2 = 77,768 lbs.
What is pile load capacity?
The ultimate bearing capacity of a pile is the maximum load which it can carry without failure or excessive settlement of the ground. The bearing capacity of a pile depends primarily on 3 factors as given below, Type of soil through which pile is embedded. Pile dimension (cross section & length of pile)
Which of the following formula can be used for determining the efficiency of pile group?
2. Which of the following formulae can be used for determining the efficiency of pile group? Explanation: Converse Labarre formulae, Seiler-kenney formulae, Feld’s rule are some of the common formulae available for determining the efficiency of pile group. 3.
Which piles should be selected in situation where there is a possibility of the soil being chemically aggressive?
In situation where there is possibility of the soil being chemically aggressive, high quality precast concrete piles should be selected.
Which of the method is used for under reamed piles?
Explanation: The under-reamed piles are connected by a reinforced concrete beam, known as capping beam or grade beam.
Which of the following piles is a cast in-situ type of concrete pile?
Which of the following piles is a cast-in-situ type of concrete pile? Explanation: Raymond standard pile and Raymond step-taper pile are the common types of cast-in-situ piles.
How the piles are classified What are the factors governing the selection of choice of a type of pile?
The factors that affect the selection of pile foundations are, Soil conditions. Loads from structures. Nature of loads.
What are piles construction?
A pile is a long cylinder made up of a strong material, such as concrete. Piles are pushed into the ground to act as a steady support for structures built on top of them. Piles transfer the loads from structures to hard strata, rocks, or soil with high bearing capacity.
How do you calculate the load capacity of a crane?
Measure geometric components
- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.
What is under reamed pile What is its primary objective?
The anchorage provided by the under-ream pile prevents cracks in floors and walls of buildings in expansive soil areas. Single under-ream piles have been extensively used for single- or double-storied buildings. The provision of an additional bulb increases the load-carrying capacity by about 50\%.
