ASTM E564
Full Name
ASTM E564 – Standard Practice for Static Load Test for Shear Resistance of Framed Walls for Buildings
Scope
ASTM E564 outlines a standardized procedure for determining the shear resistance of framed walls used in building construction. This practice employs static load testing, a crucial method for assessing the structural integrity and safety of wall assemblies subjected to lateral forces, such as those experienced during wind or seismic events.
Key aspects of ASTM E564 include:
- Test specimen: the standard details the construction and preparation of test specimens, typically representative full-size sections of the framed wall assembly intended for use in the building. This includes specifications for framing materials, sheathing, fasteners, and any applied finishes.
- Loading method: ASTM E564 focuses on static load application, meaning the force is applied gradually and held constant until the desired deformation or failure point is reached. This contrasts with dynamic testing methods that simulate rapid load changes.
- Instrumentation and measurement: the standard specifies instruments and procedures for accurately measuring applied load, deflection at various points on the wall assembly, and other relevant parameters throughout the test. This data is critical for determining the wall’s load-deflection behavior and ultimate shear strength.
- Analysis and reporting: ASTM E564 provides guidance on analyzing the collected data, including the determination of key performance metrics such as the maximum load capacity, stiffness, and failure mode. The standard also outlines reporting requirements to ensure clear and comprehensive documentation of the test results.
