Abstract: This paper aims to show, through numerical parameter analysis on a finite-element method with axisymmetry hypothesis, the long-term effect involving the creep and shrinkage of the concrete lining in deep tunnel problems. ...

Abstract: A numerical model for the study of prestressed members with bonded and unbonded tendons has been implemented, considering the hybrid type finite element formulation for planar frames. With such an approach, accurate curvature ...
