FINITE ELEMENT PROCEDURE FOR MODELING SOILSTRUCTURE- FOUNDATION INTERACTION IN BUILDING SEISMIC DAMAGE RESPONSE

An Investigation of the Seismic Interaction of Surface Foundations and Underground Cavities Using Finite Element Method

In this study, the seismic interaction of surface foundations and underground cavities was investigated. For this purpose, a parametric study of geometric dimensions of the foundation and cavity, their location, and the effect of the interaction between surface foundations and underground cavities was evaluated. The variable parameters include the ratio of the overburden height to the foundatio...

Spectrally formulated finite element for vibration analysis of an Euler-Bernoulli beam on Pasternak foundation

  In this article, vibration analysis of an Euler-Bernoulli beam resting on a Pasternak-type foundation is studied. The governing equation is solved by using a spectral finite element model (SFEM). The solution involves calculating wave and time responses of the beam. The Fast Fourier Transform function is used for temporal discretization of the governing partial differential equation into a se...

Finite-difference modeling experiments for seismic interferometry

In passive seismic interferometry, new reflection data can be retrieved by crosscorrelating recorded noise data. The quality of the retrieved reflection data is, among others, dependent on the duration and number of passive sources present during the recording time, the source distribution, and the source strength. To investigate these relations we set up several numerical modeling studies. To ...
