Importance of soil material damping in seismic responses of soil-MDOF structure systems

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

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

The Importance of Soil and Alluvial and Quaternary Deposits Conditions in Seismic Risk Analysis

The land of Iran is a seismic active prone that is located in the mountainous and instable crust due to special geological position. Continuous tectonic stress from the Arabic and Indian plates has exposed seismic active faults. The huge and destructive earthquakes that occur every few years in this area reflect the tectonic conditions of the plateau of Iran. Since, the path of faults and fract...

Evaluation of Torsional Provisions of Seismic Codes Considering Effects of Soil-Structure Interaction

In this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real Iranian earthquake records by considering soil-structure interaction. Then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of Iran, ATC-3, New Zeland, Canada, Mexico, Austral...
