Foreword
According to requirements of "on Notification of Printing and Publishing of [Development and
Revision Plan of Engineering Construction Standard in 2007 (first edition)]", China Institute of
Building Standard Design & Research together with organizations concerned revised the former
"Standard for structural drawings" GB/T 50105-2001 into this national standard.
In the process of revision, the drafting group of this standard carried out extensive investigation by
carefully summarizing practical experience, referring to relevant international standard and
foreign advanced standard and widely soliciting opinions and finally finalized the manuscript.
This standard consists of 5 chapters and an Appendix and the major technique content includes.
General Provisions, Basic Requirements, Concrete Structures, Steel Structures, and Wood
Structure.
Revised major technique of this standard consists of the following content. 1 added computer
CAD cartographic file, computer graphic layer and regularity of computer cartography; 2 added
figure lines; 3 added representation method of text noted member reinforcements complex joint of
the concrete structure; 4 added general requirements of steel structure working diagram and
decomposition and index of the complex joint detail drawing.
This national standard was in the charge of the administration of Ministry of Housing and
Urban-Rural Development and China Institute of Building Standard Design & Research is
responsible for the explanation of specific technical contents. If any complaint and suggestion
arise during the process of implementing this standard, please write to China Institute of Building
Standard Design & Research (Address. Zhuyu International, No.2 Building, Shouti South Road,
Hai Dian District, Beijing, Post Code. 100048).
