THE P-DELTA AND SOIL-STRUCTURE INTERACTION EFFECT ON BRIDGE PIERS

The purpose of this study is to investigate the P-Delta effect on bridge piers with consideration of soil-structure interaction effect. The traditional P-Delta effect was calculated assuming the base of the structure is fully fixed. However, all structures in real life are supported by soil, and so...

The traditional P-Delta effect was calculated assuming the base of the structure is fully fixed. However, all structures in real life are supported by soil, and soil is deformable. Therefore, under wind or earthquake loads, the additional lateral deflection of a bridge pier caused by the deformation of the soil, which supports the pier, should be considered. The traditional method regarding the computation of the deflection of a pier caused by wind or earthquake loads does not take soil-structure interaction effects into account.
