National Standard of the People's Republic of China: Code for Design of Timber Structures GB 50005—2003

The code is written in Chinese and English. The Chinese text shall be taken as the ruling one in the event of any inconsistency between Chinese text and the English text.

There are totally 11 chapters and 16 appendices in this revised version. Major revisions are as follows:
1. To adjust the reliability index for timber structures based on the revised edition of Unified Standard for Reliability Design of Building Structures and Load Code for the Design of Building Structures;
2. To add design requirements on imported timbers, derivation of strength value for imported dimension lumber and major points of field-grading and main characteristics of timbers;
3. To revise and complement part of calculation on members of timber structures;
4. To add a section of light wood frame construction, with each chapter to be set up for common timber structures and light wood timber structures;
5. To make some revisions and complements on the glued laminated timber structures, which constitutes this code as an independent chapter;
6. To add a section of light wood frame construction, with each chapter to be set up for common timber structures and light wood timber structures;
7. To establish a chapter for fire protection of timber structures in light of the characteristics of timber structures
8. To get such preservations from decay and insect attack made up this code as one chapter.
