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). This standard is drafted by. Beijing Forestry University, Tsinghua University, Institute of Wood Industry, Chinese Academy of Forestry, Beijing University of Construction Xue, Nanjing University of Technology, Dehua Bunny Decoration New Material Co., Ltd., Suzhou Kunlun Green Jianmu Structure Technology Co., Ltd., Shanghai Zhongzhong Sky Green Building Technology Co., Ltd., Suzhou Xiangshan Workshop Construction Investment Development Co., Ltd., Fujian Zhangping Mucun Forest Products Co., Ltd., Dongguan Huake Dongni Instrument Co., Ltd.
