What is Seismic Analysis of Large Pile Group about?
This paper analyzes the seismic response of a large 230-pile group foundation for a critical facility subjected to earthquake shaking. Three different methods are used to obtain dynamic impedances of the pile group: (1) a rigorous semi-analytical method dividing the group into subgroups, (2) a rigorous superposition method, and (3) a simplified interaction factor method. The paper focuses on properly accounting for interaction between piles, including effects of shadowing and distance on interaction factors
