Abstract:
Considering the interaction of super structure, raft foundation and ground base by using the calculation method of ANSYS procedure and the condition of the stationary balance of the linked point between super structure, raft foundation and the distortion harmony condition, the effects of super structure stiffness on the stress, strain of the raft foundation, and effects of raft foundation on the stress and strain of super structure were analyzed; the influence regularity of the interaction was discussed. Results show that when considering the interaction, super structure bears some load of raft foundation and reduces the stress and strain, however, when considering the stiffnessof the raft foundation,because of whole bending,super structure stress isre-distributed; the added flexural stress is produced in beams, and the stress of super structure is increased. To make the projects more security and economical, the effects of interaction should be taken into consideration in the engineering design.
