Effect of soil-structure interaction on response of building frame supported on pie foundation

摘要

Superstructure frames are normally analyzed considering their bases to be either completely rigid or hinged. Notwithstanding, the foundation resting on deformable soil also undergoes deformation depending on the relative rigidities of the foundation, the superstructure and soil. Interactive analysis is, therefore, necessary for the correct assessment of the response of the superstructure. Many interactive analyses have been reported in the literature. While the majority of these analyses report either interaction of frames with isolated footings or the interaction of frame with raft foundation, few of them reports interaction of frame with combined footings. At the same time, much work is available on pile foundation (single as well as pile group). However, hardly any work reports the analysis of framed structure resting on pile foundation, thus accounting for soil-structure interaction. Brief review of the literature on the interaction analyses of framed structures and analyses of pile foundation is given in the subsequent section.
