Bondslip reinforcements and pile foundations
Title Bondslip Reinforcements and Pile Foundations Author(s) Gerd-Jan Schreppers, TNO DIANA BV Published January 2015 Pages 5 Keywords bond-slip, bondslip, embedded reinforcement Summary In the embedded reinforcement concept in DIANA the reinforcement particles share the displacement degrees of freedom with the continuum elements in which they are located. As a consequence no relative displacement between […]
