Currentness
Tiedown assemblies that are not part of an engineered tiedown system shall be listed as having been tested and found to be in compliance with the requirements of this section.
(a) A tiedown assembly consists of the ground anchor component and anchoring equipment. Anchoring equipment includes such components as:
(1) a tie, which connects the ground anchor to the MH-unit;
(2) a tensioning device, such as a turnbuckle or a yoke-type fastener; and
(3) fastening devices, such as an eye-bolt or a U-bolt-type cable clamp.
(b) A tiedown assembly shall be designed to prevent self-disconnection. Open hook ends shall not be used in any part of the tiedown assembly.
(c) Flat steel strapping used as a component of a tiedown assembly shall comply with the specifications and testing methods of ASTM Standard D3953-91, “Standard Specification for Strapping, Flat Steel and Seals,” which is hereby incorporated by reference.
(d) A ground anchor component designed for the connection of multiple ties and the means for the attachment of the ties shall be capable of resisting, without failure, the combined working load of the maximum number of ties that can be attached to the anchor.
(e) A tiedown assembly shall be tested by applying an increasing test load to the point of failure in order to determine the assembly's capacity for resistance. A working load for the tiedown assembly shall be established from the test results, which shall be two-thirds ( 2/3 ) of the amount of resistance the tiedown assembly endured without failure.
(f) The tiedown assembly shall be tested while the ground anchor is installed as recommended by the manufacturer.
(1) The type of soil in which the ground anchor is installed for the application of a test load shall correspond to one of the classes of materials shown in California Residential Code, Table R 401.4.1. The working load of the listed tiedown assembly used in the calculations shall be for one-thousand five-hundred (1,500) pound soil, consisting of clay, sandy clay, silty clay and clayey silt, as classified in the California Residential Code, Table R 401.4.1.
(2) The test load shall be applied from the direction of the tie.
(g) Failure of the ground anchor component consists of the following occurrences:
(1) The application of the test load results in an uplift of the ground anchor greater than two (2) inches or a side deflection of the ground anchor greater than three (3) inches; or
(2) The ground anchor, including the means of attachment of the tie, breaks, separates, or is deformed in a manner that threatens the integrity of the tiedown assembly. A deformity that threatens the integrity of the tiedown includes one that would allow the tie to separate from the ground anchor or that would cause the tie to wear and break.
(h) Failure of a component of the anchoring equipment consists of the following occurrences:
(1) The tie stretches to a length more than two (2) percent greater than the length of the tie prior to the application of the test load; or
(2) A component of the anchoring equipment or the attachment point to the MH-unit yields or fractures upon application of the test load; or
(3) A component of the anchoring equipment or the attachment point of the MH-unit is deformed by the working load in a manner that is a threat to the integrity of the tiedown assembly.
(i) The listing for the tiedown assembly shall include the following information:
(1) The model identification number of the tiedown assembly;
(2) The working load of the listed tiedown assembly used in the calculations, shall be calculated for one-thousand five-hundred (1,500)-psf soil, consisting of clay, sandy clay, silty clay and clayey silt, as classified in the California Residential Code, Table R401.4.1; and
(3) Installation instructions for the tiedown assembly, including the manner in which the ground anchor component must be inserted into the ground in order to maintain the working load for which the tiedown assembly is rated. Such instructions include the angle at which the anchor must be inserted and the angle at which the tie must be attached.
(j) The ground anchor component of a listed tiedown assembly shall contain a permanent label that provides the manufacturer's name and the listed model identification number of the tiedown assembly. The label shall be located on the anchor in a place that it is visible after installation, and the information shall be provided on the label in a manner that is easy to read.
