Transient Response Analysis of a Submerged Floating Tunnel under Seismic and Wave Excitations
In this study, a numerical procedure is described for the transient response analysis of a submerged floating tunnel with reference of a designed tunnel in Japan. Tension legs seizing the tunnel are simply modeled by a spring elements and the tunnel itself is assumed by two rigid bodies between which a flexible joint is used. A recorded seismic excitation is used while the wave load is calculat...
متن کاملOPTIMUM PERFORMANCE-BASED DESIGN OF CONCENTRICALLY BRACED STEEL FRAMES SUBJECTED TO NEAR-FAULT GROUND MOTION EXCITATIONS
This paper presents a practical methodology for optimization of concentrically braced steel frames subjected to forward directivity near-fault ground motions, based on the concept of uniform deformation theory. This is performed by gradually shifting inefficient material from strong parts of the structure to the weak areas until a state of uniform deformation is achieved. In this regard, to ove...
متن کاملDeformation Performance of the Karkheh Earth Dam with Mixed and Pure Clay Coreunder Seismic Excitations
The number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. Nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. In the past, earth dams usually designed with pure clay core, but in recent decades t...
متن کاملMoving 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...
متن کاملHydrodynamic Performance Evaluation of Step Floating Breakwaters through Experiment and Artificial Intelligence
A new type of floating breakwaters (FBs) is introduced by changing the longitudinal section of π-shaped FBs into a stepwise shape. The hydrodynamic performance of so-called step floating breakwaters (SFBs) is evaluated through 144 experiments on SFBs of different types as well as π-shaped FBs. Initially, using the experimental data, the performance of SFBs was evaluated by comparison against π-...
