An axial compressive force-pulse (rapid) load test applied directly to a deepfoundation element, per ASTM D7383 or EN ISO 22477-10. The loading lasts tens to afew hundred milliseconds, between the seconds-to-minutes timescale ofdiggs:StaticLoadTest and the millisecond-or-shorter timescale ofdiggs:DynamicLoadTest, and the measured force pulse needs an inertial and dampingcorrection (analysisMethod) to give a load-settlement response. EN ISO 22477-10classifies a rapid test by purpose, as an investigation test (a sacrificial pileloaded to the ultimate limit state) or a control test (a working pile loaded to aspecified load above the serviceability limit state); ASTM D7383 does not name thedistinction, so give testCategory where it applies and leave it out otherwise. Thetwo named analysis methods, the Unloading Point Method and its modified form, areused by the practitioner communities of both standards.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
