WebThe geotechnical design of spun pipe piles considers the development of axial geotechnical resistance through end bearing on bedrock in accordance with the methodology for drilled shaft tip resistance on rock and the selection of an appropriate resistance factor. For design, the structural capacity is based on the steel Webthe single resistance factor, and the importance factor is set to 1.0. The resistance factor in this paper can thus be thought of as the product of a geotechnical resistance factor (capturing site uncertainty) and a consequence factor (capturing failure consequence, the consequence factor is the inverse of the im-portance factor). new employee injury rates https://t-dressler.com
