Standard Guide for Conducting Flexural Tests on Beams and Girders for Building Construction

SCOPE
1.1 This guide covers the flexural testing of beams and girders under simulated service conditions to determine their structural performance characteristics. Methods following this guide are intended primarily for constructions that may not conform with the relatively simple assumptions upon which well-known flexural theories are based. In some cases, they are also suitable for determining the structural adequacy of the design, materials, connections, and fabrication techniques. The methods are not intended for use in routine quality control tests.
1.2 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. For specific precautionary statement, see 7.1.
