Pushover analysis of bridges including soil-structure interaction effects
Abstract
This paper deals with the effects of soil-structure interaction (SSI) on the displacement capacity of multi-span RC bridge founded on shallow foundations. Modal pushover analyses are carried out in transverse direction. Target displacement of the monitoring point is calculated using N2 method The SSI is considered through boundary springs according to NEHPR Two different soil properties are considered according to EN1998-1. Analyses are carried out using SAP2OOO, considering fixed- and flexible-base models. The obtained results are discussed.
