Integrated foundation-structure seismic assessment through non-linear dynamic analyses

Probabilistic Seismic Assessment of Structure, Foundation, and Soil Interacting Systems

Seismic Vulnerability assessment of concrete railway bridge using nonlinear analyses

Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...

Seismic Soil-foundation Interaction Analyses of the New

A new bridge that will replace the existing Woodrow Wilson Bridge is under construction over the Potomac River in Washington, DC. The river piers are supported on cylindrical steel piles of 72, 54 and 48 inches in diameter. The longest piles (at the bascule piers) are approximately 200 ft long. Outside the river, nearly all piers are supported on 24-inch square prestressed concrete piles. Altho...

Non-Linear Analysis of Asymmetrical Eccentrically Stiffened FGM Cylindrical Shells with Non-Linear Elastic Foundation

In this paper, semi-analytical method for asymmetrical eccentrically stiffened FGM cylindrical shells under external pressure and surrounded by a linear and non-linear elastic foundation is presented. The proposed linear model is based on two parameter elastic foundation Winkler and Pasternak. According to the von Karman nonlinear equations and the classical plate theory of shells, strain-displ...

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...
