A time interval of zero is similar to the EOID affliction. When utilizing the proprietary Laptop software package application GRLWEAP™ made by Pile Dynamics, Inc. it is crucial to recognize that these WEAP analyses are made using a default time interval of 168 several hours (7 days) to report their predicted ultimate resistance capacity.
