Standard Practice for Calculating the Superimposed Load on Wood-frame Walls for Standard Fire-Endurance Tests
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers procedures for calculating the superimposed axial load required to be applied to load-bearing wood-frame walls throughout standard fire-endurance and fire and hose-stream tests.
1.2 The calculations determine the maximum load allowed by design for wood-frame wall assemblies under nationally recognized structural design criteria.
1.3 This practice is only applicable to those wood-frame assemblies for which the nationally recognized structural design criteria is the
1.4 The system of units to be used is that of the nationally recognized structural design criteria. For the NDS, the units are inch-pound.
1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.6 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.
Significance and Use
Test Methods E 119
4.1.1 Alternatively, the standard fire endurance test methods shall be conducted by applying an axial load that is less than the maximum allowable axial load as addressed by the NDS and this practice, but these tests shall be identified in the test report as being conducted under restricted load conditions. The superimposed axial load, as well as the superimposed axial load as a percentage of the maximum allowable axial design load as addressed by the NDS and this practice shall be included in the test report.
This practice describes procedures for calculating the superimposed axial load to be applied in standard fire endurance tests of wood-frame wall assemblies.
Statements in either the fire endurance test method standard or the nationally recognized structural design standard supercede any procedures described by this practice.
The NDS shall be consulted to ensure calculations are in compliance with all applicable provisions of that document.
