A 3D Numerical Investigation on Seismic Behavior of Sleeved-Pile with Soil–Rubber Mixture in Foundation of Structures
The installation and maintenance of buildings mounted on deep piles employing the seismic isolation system could be problematical and costly for structural applications. Regarding mentioned issue, seismic isolation using sleeved-pile while considering the damping behavior of the soil–rubber mixture as the only source of damping have been proposed. The purpose of this study is to investigate the effects and performance of sleeved-pile with soil–rubber mixture on the response of the system. Numerical modeling of soil–pile-structure system is conducted using Abaqus software. Three models have been investigated including 5, 10 and 15 floors representing low-, mid- and high-rise buildings in both conventional system and sleeved-pile with sand–rubber mixture. The results have shown that this system has reduced the inter-story drift and the horizontal acceleration on the foundation and structures consequently reducing the created forces in the structure. The advantages of the proposed system have been laid in reduction of initial construction costs by the device eliminations such as various types of dampers, easy access to resources, the lack of high technology requirement and the simultaneous elimination in both seismic control of structures and environmental protection problems.
