Foreword

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

This standard replaces JG/T 209-2007 "building energy damper." this standard is JG/T 209-2007 "building energy damper" revision, compared with the JG/T 209-2007 main technical changes as follows.

--- Added "metal yielding damper, buckling restraint energy consumption support terms and definitions" (see 3.3,3.4);

--- Added "metal yielding dampers, buckling restraint energy consumption support classification and labeling" provisions (see 4.3,4.4);

--- Added "metal yield damper, buckling restraint energy consumption support technical requirements" (see 6.3,6.4);
