Web19 Dec 2024 · To account for creep effects, secondary compression index is mostly used internationally. Therein a linear relationship is assumed in the final part of the consolidation phase in an e-logt diagram. In Scandinavia, the creep number rs of Janbu ( 1969) is more often used. Therein the time resistance R is defined as follows: WebCompression index ண.
