Soil-Structure Interactions of Tube-in-Tube System of Tall Buildings Based on ODE Solver

Abstract:

A new analytical method for the analysis of interactions between the superstructure and foundation and foundation soil of a tall building is formulated. The computational model of a structural system and its foundation are simplified equivalently and continuously into a three-dimensional model, a combination of thin-walled tubes on a semi-infinite elastic subgrade. The various stiffness coefficients for evaluating elastic strain energy stored in foundation soil are as well derived by using the principle of energy equivalency. Some satisfying conclusions are obtained by the interaction analysis for the tube-in-tube structural system adopted by Guangdong Guomao Building.
