Dynamic Response of Submerged Vertical Cylinder with Lumped Mass under Seismic Excitation

numerical investigation on accuracy of mass spring models for cylindrical tanks under seismic excitation

the main objective of this article is evaluation of the simplified models which have been developed for analysis and design of liquid storage tanks. the empirical formulas of these models for predicting maximum sloshing wave height (mswh) are obtained from mass spring models (msm). a finite element modeling (fem) tool is used for investigating the behavior the some selected liquid storage tanks...

Simplified Seismic Dynamic Analysis of Sloshing Phenomenon in Rectangular Tanks with Multiple Vertical Baffles

Sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. In recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. On the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...

The Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics

Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...

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...

Nonlinear dynamic response of floating piles under vertical vibration

This paper presents the influence of non-linearity on the dynamic response of floating pile foundation subject to vertical vibration. A detailed theoretical investigation of stiffness and damping parameters is made for floating piles with different shear modulus reduction ratio of the weak zone soil. The accuracy of the non-linear analysis for predicting the dynamic response depends upon the ch...
