Dynamic behavior of soil-foundation-structure systems subjected to scour

چکیده

Earthquake and scouring are the leading causes of bridge failure worldwide, resulting not only in casualties fatalities but also enormous societal economic losses. A great number bridges earthquake-prone countries cross rivers have shallow foundations, which renders them highly vulnerable to combined effects earthquake flood-induced scour. Thus, research on dynamic response with foundations under scour hazards is timely imperative. This study investigates problem through development a numerical model for evaluating effect impedance functions massless rigid strip foundation resting homogenous elastic half-space. The developed then used an extensive parametric analyzing changes fundamental frequency piers different combinations geometrical mechanical properties soil-structure-foundation system. results shed light vibration important implications inverse techniques identification based evaluation modal properties.

Soil–Foundation–Structure Interaction Effects in Seismic Behavior of Bridges

Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented in this paper addresses the influence of inelastic behavior of both the soil and the structural components during seismic response evalu...

Nonlinear Dynamic Analysis of Pile Foundation Subjected to Strong Ground Motion Using Fiber Elements

In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...

Dynamic soil±pile±foundation±structure interaction: records and predictions

The problem of soil±pile±foundation±superstructure interaction is examined, and a simple rational procedure to analyse the response of a structure supported on pile groups is presented. This procedure combines theories for the computation of the dynamic impedances and kinematic±seismic response factors of pile foundations with a multi-degree-of-freedom structural model. The procedure is applied...
