Standard Test Method for In Situ Compressive Stress within Solid Unit Masonry Estimated Using Flatjack Measurements
|Publication Date:||1 January 2004|
|ICS Code (Walls. Partitions. Façades):||91.060.10|
This test method covers the determination of the average compressive stress in existing unreinforced solid-unit(Footnote 2) masonry. This test method concerns the measurement of in-situ compressive stress 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 in place.
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.

Footnote 2 - Solid-unit masonry is that built with stone, concrete, or clay units whose net area is equal to or greater than 75 % of the gross area.
