STIFFNESS OF PILE GROUPS DURING LATERAL PUSHOVER

Research output: Contribution to journalArticlepeer-review

Abstract

A pushover analysis is carried out to study the performance of square precast piles supporting quasi-static lateral loading conditions as an approach to determine single piles, single pile groups, and multi pile groups failure criteria. The piles are modeled as embedded beam elements. The structure is modeled and analyzed using Plaxis3D. Pile stiffness, yielding, and hinge formation patterns in the piles during the increment of quasi-static lateral loading are simulated with Plaxis 3D. During displacement increment, stiffness changes of the single pile, pile groups during displacement increment. Piles and piles group stiffness ratio will be observed between pile stiffness at a certain displacement to its initial stiffness. Piles dan pile groups damage level criteria for a certain range of displacement are obtained from pile failure observation and pile stiffness reduction during displacement increment.
