Two legs of the Chinese JZ-20 multi-leg platform were instrumented to measure the loads that result from advancing sea ice floes. One leg was equipped with five load panels, which allowed the local load and total leg load to be determined. The other leg was strain-gauged, providing another estimate of the leg load. In 1990, the loads were measured simultaneously on two legs of the platform, providing a unique data set for assessing the resultant load on two legs, in comparison to the total load on an individual leg. The simultaneity of the measured ice load on two legs is examined using a representative sample of the load information from each leg. Peer reviewed: Yes NRC publication: Yes
