Procedure A<br />
The measurement value of resistance is equal to the characteristic<br />
resistance divided by the partial safety factor for the material resistance<br />
of the respective failure type. Characteristic resistances are generally<br />
specified in the approvals (tensile load: steel failure, extraction; traverse<br />
load: steel failure). Characteristic resistances are determined according<br />
to general measurement equations for the measurement of concrete<br />
failure under tensile load and traverse load (tensile load: concrete failure,<br />
cracks; traverse load: concrete failure on side opposite the load- bearing<br />
side, concrete edge failure). Edge and center distance influences are<br />
considered as well as the component thickness using the concrete<br />
capacity procedure, if necessary. The existing concrete compressive<br />
strength can also be factored in. In this measurement, the minimum<br />
measurement value of resistance in a load direction is a decisive factor.<br />
The heaviest loaded anchor is relevant for off-center stressed group<br />
fixings for steel failure and extraction under tension as well as steel failure<br />
under lateral load.<br />
The partial safety factors for material resistance depend on the type of<br />
failure and the installation safety of the anchor system and are specified<br />
in the approval documents.<br />
The partial safety factor for extraction and concrete failure under tension<br />
is determined from the mounting safety factor of an anchor or its anchor<br />
size. This mounting safety factor is derived from the results of tests that<br />
are performed as part of the approval procedure. Mounting inconsistencies<br />
that can occur at the construction site are simulated in these tests, however<br />
it is assumed that crude errors in mounting (e.g. using the wrong drill) are<br />
ruled out by appropriate measures at the construction site.<br />
