Paper Title:
3-D Numerical Analysis on Performance of Prestressed and Precast Concrete Segment Joint
  Abstract

The rotational angle of joint is the key factor for segment lining design. Using the nonlinear finite element program of MARC (MSC2003), the 3D numerical analysis on segment joint of prestressed concrete lining has been carried out. During the analysis, Coulomb and Stick-slip friction models were used as the friction type between the concrete and the prestressing steel strands. The selection of friction model used in the numerical analysis is very important. The study showed that the Stick-slip friction model is more suitable than Coulomb friction model for analysis of the P&PCSL joint. The value of friction coefficient should be thought over carefully.
