I have read many papers by Dr. Fellenius. It is understood that the dragload need not be deducted from the assessed geotechnical capacity. It is considered that the pile settlement under the limit state is larger than the settlement that induced the NSF.
However, for case of the end-bearing bored pile on bedrock, it is expected the pile settlement would be small relative to the settlement of surrounding soil. Should the dragload apply to geotechnical capacity for the end-bearing bored pile founding on bedrock???
Please give me some advices. Thanks a lot!!!

Well, read them again and you will realize that for your case, the neutral plane will be located at the pile toe and the maximum load at the pile toe will be the applied dead load plus the drag load ( = shaft resistance mobilized along the full length of the pile). Settlement is not the main issue, but strength of the pile might be, as well as the strength of the bedrock.
