GB/T 37745-2019Static and cyclic lateral load test methods for timber structure shear walls (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify the ISO 21581.2010 "wood structure shear wall static load and low cycle repeated horizontal loading test

method".

This standard has more structural adjustments than ISO 21581.2010. This standard and ISO 21581.2010 are listed in Appendix A.

The chapter number is compared to the list.

There are technical differences between this standard and ISO 21581.2010. Appendix B gives the corresponding technical differences and their causes.

Watch list.

This standard also made the following editorial changes.

--- Added informative Appendix C, providing a static load and low cycle repeated horizontal loading test record table for wood structure shear walls;

--- Modified the standard name.

This standard was proposed by the National Forestry and Grassland Bureau.

This standard is under the jurisdiction of the National Timber Standardization Technical Committee (SAC/TC41).

1 Scope

This standard specifies the terms, definitions and symbols, test pieces and test design of the static load and low-cycle repeated horizontal loading test methods for wood structural shear walls.

Preparation, test methods, test results, test reports.

This standard is applicable to the determination of the anti-side properties of static and low-cycle repeated loads of wood-structured shear wall systems under horizontal action, including failure modes.

Formula, maximum load, ultimate displacement, load-displacement curve, hysteresis curve of reciprocating load and skeleton curve.
