Seismic Analysis of Pile Groups

Author : Dr. Moinuddin Ahmed and Dr. D. Babu Rao

Engineering design of structures due to earthquake is a unique problem.Pile foundations are commonly used to support heavy structures on weak soils. Piles are commonly used in groups. Seismic resistant design of pile group involves assessment of stiffness of an individual pile and the stiffness of pile group accounting interaction effects. The natural period of the pile-soil-structure system is an important parameter for the estimation of seismic force which depends on group stiffness.
