Pile group capacity = efficiency of the pile group × single pile capacity× number of piles Center to center distance between piles = 48 in. Since the diameter of piles is 12 in, center-to-center distance is 4D. Efficiency of the pile group = 0.78 (AASHTO table). Pile group capacity ...
Computational Method: The ultimate axial capacity of piles is computed using the static method of analysis in general accordance with the API RP 2A (2000). In this method, the total ultimate capacity of a pile is taken as the sum of the skin friction on the pile wall. If the piles will...
capacity of the pile and the temperature. Furthermore, Wu et al.11scrutinized the influence of pile foundation thawing process on the bearing capacity of single pile in frozen soil area, compared and analyzed the difference between dynamic-load and static-load conditions, and gave the calculation ...

As: side surface area of pile, q: unit end bearing capacity, Ap: gross end area of pile. There are many methods for calculating the pile capacity for cohesive and noncohesive soil. One of these methods from API is presented below as a guideline for calculating the pile capacity. 1. For...
For purpose of simplifying the analyses considering the extensive number of parameters and large data set, Jeon and Rahman (2008) divided the data into five categories based on the ultimate pile capacity, as detailed in Table 3. In this paper, for each category 70% of the data patterns were...
The slow rate of charging is the result of using low battery charge currents to avoid damage (a problem that is constantly being improved), as well as the energy capacity of the local grid connection. Adding a high power connection can create issues in regards to safety and reliability. ...
