A New Approach in Equivalent Spring-Dashpot Method for Seismic Soil-Structure Interaction Analysis of Long Bridges Including Non-uniform Excitations
Abstract This paper is conducted on evaluating the seismic responses of long bridges under the effect of the soil-structure interaction (SSI) and spatially varying earthquake ground motions (SVEGM). The commonly used spring-dashpot method for analysis of the pile-supported structures under the effect of (SSI) improves to a more capable model. Also, a comprehensive investigation of the dynamic response of a long bridge subjected to spatially varying earthquake ground motions (SVEGM) is performed based on a proposed analytical model which includes the effect of (SSI). The modeling methodology is discussed in detail. To emphasize the importance of the SVEGM and SSI, bridge responses are also determined for the uniform ground motion and fixed base cases. This study proposing a compatible analytical model concerns the relative importance of the SSI and SVEGM and shows that these effects cannot be neglected in seismic analysis and design of long bridges.
