Standard Test Method for In Situ Measurement of Masonry Deformability Properties Using the Flatjack Method
|Publication Date:||1 January 2004|
|ICS Code (Walls. Partitions. Façades):||91.060.10|
This test method describes an in situ method for determining the deformation properties of existing unreinforced solid-unit(Footnote 2) masonry. This test method concerns the measurement of in-situ masonry deformability properties in existing masonry by use of thin, bladder-like flatjack devices that are installed in saw cut mortar joints in the masonry wall. This test method provides a relatively non-destructive means of determining masonry properties.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
