Interaction Analysis of the Superstructure and Raft Foundation for Tall Building with Podium

Abstract:

Based on the three-dimensional computation model, the actual project ,a high-rise building with podiums on the jointless raft foundation, is made nonlinear numerical analysis, which aims at studying the characters of superstructure-foudation-soil’s interaction, and analyzing the stress features in raft foundations under the former interaction , the distribution of stresses on foundation plate，and the range of stress dispersion about subgrade reaction. Through the factors, which can affect superstructure-foudation interaction, are analyzed , such as superstructure’s stiffness, foundation’s stiffness and soil’s stiffness. Then, the distribution rule of stress and deformation about superstructure-foudation interaction. Which can provide some calculation basis for this kind of foundation design.
