A study on dynamic behavior of medium-rise building with pile foundation supported by different diameter piles

Abstract

When a building has high- and low-rise part or eccentrically-located core unit, it may need to use pile foundation supported by different length or diameter piles because of eccentricity for planar loading. In this study, the influences upon the dynamic behavior of building and pile by irregular pile position for the medium-rise building with pile foundation supported by different diameter piles are investigated using 3D FEM. As a result, the irregularity of the pile group has relatively less impact on the response of the building. However, It is found that the irregularity makes significant impact on response of piles.
