Gh.H. Ranjbar; K. Shahriar; K. Ahangari

Volume 11, Issue 3 , Summer 2020, , Pages 737-751

http://dx.doi.org/10.22044/jme.2020.8979.1785

Abstract
  Although segmental tunnel linings are often used for seismic areas, the influence of segment joints on the segmental lining behavior under seismic loading has not been thoroughly considered in the literature. This paper presents the results of a numerical study investigating the effects of the rotational, ...  Read More

2. Effect of segmental joint stiffness on tunnel lining internal forces under static conditions

Gh. H Ranjbar; K. Shahriar; K. Ahangari

Volume 10, Issue 4 , Autumn 2019, , Pages 1031-1043

http://dx.doi.org/10.22044/jme.2019.8581.1738

Abstract
  According to the wide application of segmental lining in mechanized tunneling, recognizing the behavior of segmental lining joints is important in tunnels designing. In the structural analysis of the tunnel segmental lining, segmental joints can be considered as elastic joints, and their stiffness characteristics ...  Read More

Seyed S. Mousavi; M. Nikkhah; Sh. Zare

Volume 10, Issue 1 , Winter 2019, , Pages 95-112

http://dx.doi.org/10.22044/jme.2018.7159.1566

Abstract
  In this work, we tried to automatically optimize the cost of the concrete segmental lining used as a support system in the case study of Mashhad Urban Railway Line 2 located in NE Iran. Two meta-heuristic optimization methods including particle swarm optimization (PSO) and imperialist competitive algorithm ...  Read More

4. Evaluation of structural analysis of tunnel segmental lining using beam-spring method and force-method (Case study: Chamshir water conveyance tunnel)

M. Nikkhah; Seyed S. Mousavi; Sh. Zare; O. Khademhosseini

Volume 8, Issue 1 , Winter 2017, , Pages 111-130

http://dx.doi.org/10.22044/jme.2016.573

Abstract
  The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms ...  Read More
