Analysis of Influence of Raft Stiffness on Tall Building Interaction System

Abstract

The raft foundation has been widely applied to tall building, in consideration of the stress state is complex and the stress mechanism is unclear, there are many unreasonable problems while determined the raft thickness at this stage. This paper used the finite element method and the interaction design method, on the basis of analysis of stress and deformation under the condition of different raft thickness, get the raft stress and deformation principle, provides a reference experiences to practical design.
