Total Ice Forces on Multi-legged Structures

Abstract

The total horizontal ice force acting on multi-legged structures in ice-infested seas is estimated by summing the force on a single pile. Non-simultaneous loading of first peak force and subsequent force acting on each pile as well as simultaneous loading of first peak force are considered in the method. It is obtained that total ice force of nonsimultaneous loading, which is more realistic case, is estimated to be approximately 80% of that of simultaneous loading.
