Piles are used when the soil near the ground surface is not strong and the weight of the building must be carried by deeper soil layers. Is the static friction between the piles and soil along the entire length of the piles is taken into consideration when determining the piling needs?

yes friction between piles and soil taken into conideration and it is one of prencipals of chosen the pile

Usually piling considers end bearing resistence or skin friction. If the layer of soil beneath in strong enough to support the pile whereby the set of the last blow is less than 25mm to the previous blow, we consider it set or based on end bearing. However, if the pile is not piled to set, either due to the weak soil or high cost to pile to set, then an alternative is to calculate the skin friction to see if it can support the design load based solely on skin friction.

There are some pile designs that depend strictly on skin friction to do their job. This is very common where there are no sand layers or similar supporting features in the soil.

when you say friction piles these are really designed for frictions on the soil rather than the bed rocks were non friction piles are usually use these friction piles are usually tubular piles driven in an slight angle or what they called baterred piles

It can be, but depends on what type of pile your designing and what the soil conditions are around and below the pile.
