Hydrodynamic Analysis of Submerged Floating Tunnel Structures by Finite Element Analysis

Moving Load Analysis of Submerged Floating Tunnels

The concept of floating submerged tunnels becomes increasingly attractive idea to cross the straits. The structural solution in these bridges includes buoyancy force on tunnel body plus tension in mooring tethers. This paper investigates the effect of submergence on the dynamic response of submerged floating tunnels due to moving load. The inertial effect of the fluid on the submerged structure...

Appropriate Loading Techniques in Finite Element Analysis of Underground Structures

Stability of underground structures is assessed by comparing rock strength with induced stresses resulted from ground stresses. Rock mass surrounding the opening may fail either by fracture or excessive deformation caused. Accurate calculation of induced stresses is therefore fundamental in the stability analysis of an opening. Although numerical methods, particularly finite element method, are...

Finite Element Analysis of Solids and Structures

The finite element method is a numerical method for obtaining approximate solutions for boundary value problems that are defined in terms of a set of governing mathematical equations, boundary and/or initial conditions, constitutive laws and other secondary relations such as the strain-displacement relations. In general, any one of a number of different principles (e.g., virtual work principle,...
