Numerical Simulation of Piles Subjected To Lateral Spreading and Comparison with Shaking Table Results
Pile foundations are relatively vulnerable to lateral loads. During liquefaction-induced lateral spreading, this vulnerability is particularly conspicuous due to a loss of strength and stiffness in the liquefied soil. A nonlinear effective stress analysis incorporating an elastoplastic constitutive model based on Finite Difference Method (FLAC2D program) was used to numerically simulate shake t...

Numerical modeling of liquefaction-induced lateral spreading
ABSTRACT: Liquefaction-induced lateral spreading of soils caused by strong shaking requires careful evaluation to be properly accounted for in geotechnical, and structural design of strategic infrastructure located in highly active seismic coastal regions. Although a large number of empirical and semiempirical models are available, there is still a lot of inconsistency in their predictions. In ...
متن کاملOn the Optimum Placement of Dissipators in a Steel Model Building Subjected to Shaking-Table Tests
The following research presents the numerical and experimental results obtained on a reduced scale steel model of a medium-rise building structure dynamically protected with energy dissipaters. The steel-steel friction dissipates energy as the structure undergoes interstory drifts. A preliminary numerical analysis is performed to determine the best position of the friction dampers in the longit...
متن کاملLiquefaction Triggering Criterion Using Shake Table Test
Earthquake induced liquefaction in saturated granular soils is an important phenomenon causing severe damages. In order to minimize the ill-effects due to liquefaction, various lab tests, field tests are being used which assess the liquefaction potential. In the present study the shake table test has been used for assessing soil liquefaction of loose saturated cohesionless sand by simulating ea...
