FIRST YEAR RIDGE LOAD ESTIMATION ON A VERTICAL SIDED STRUCTURE

Abstract

This paper describes the experimental study on the first year ridge load. The authors attempted to estimate ridge load by the ice tank tests despite the lack of the field data setting rough assumptions. Ridges were built in the ice tank using molds. The consolidation depth was controlled with the insulation sheet and room temperature. 800mm wide rectangular indentor with segmented ice pressure panels in water line and ridge keel direction was used to measure the local pressure characteristics. The tests were performed varying the indentation velocity, compliance of the indentor. An estimation of the fist year ridge load exerted on a vertical sided structure is attempted using the test results.
