GB 50205-2001: Code for Acceptance of Construction quality of Steel Structures

This Code is divided into 15 chapters, including General, Terms, Symbols, Basic Requirements, Admittance of Raw Materials and Finished Products, Welding Work, Connection Work of Fasteners, Processing Work of Steel Parts and Copper Components, Assembly Work of Steel Elements, Test Assembling Work of Steel Elements, Installation Work of Single-layer Steel Elements, Installation Work of Multilayer or High Steel Elements, Installation Work of Net-type Steel Structures, Preparation and Installation Work of Metal Contour Plates, Coating Work of Steel Structures, Acceptance of Subitem-works of Steel Structures, and 9 appendixes. The Work of Steel Structures is divided into 10 subitem-works in principle, which are presented in separate chapters respectively. Though the Admittance of Raw Materials and Finished Products is not one of the subitem-works, it is presented in one independent chapter, aiming at emphasizing and enhancing the importance of the admittance inspection of raw materials and finished products and therefore ensuring the construction quality by controlling the quality of the source. Additionally, the Acceptance of Subitem-works of Steel Structures is also presented in an independent chapter in order to provide further convenience for the operation of the acceptance of construction quality.

Preface
This Code was compiled by revising the Code of Acceptance of Construction Quality of Steel Structures (GB 50205-95) and the Standard of Inspection and Assesment of Construction Quality of Steel Structures (GB 50221-95). It was jointly drafted by the General Architecture Research Institute of Metallurgy Ministry and other related organizations, according to the Notice on the Issue of the Plan of Preparing and Revising the Construction Standards during 2000 - 2001 (JB [2001] No. 87).
During the revision, the team responsible for the compilation have carried out extensive surveys; summarized the practical experiences on the acceptance of construction quality of steel structures in China; taken the current version of the state standard of the Uniform Standard of Acceptance of Construction Quality of Steel Structures (GB 50300) as the basis and revised it holistically according to the approach of "Separate the test and evaluation; strengthen the acceptance; enhance the means and process control"; widely solicited the views and opinions, in various ways, from the relevant organizations of the country; and modified the main issues repeatedly, so as the approval-version is finalized. This code is divided into 15 chapters, including General, Terms, Symbols, Basic Requirements, Admittance of Raw Materials and Finished Products, Welding Work, Connection Work of Fasteners, Processing Work of Steel Parts and Copper Components, Assembly Work of Steel Elements, Test Assembling Work of Steel Elements, Installation Work of Single-layer Steel Elements, Installation Work of Multilayer or High Steel Elements, Installation Work of Net-type Steel Structures, Preparation and Installation Work of Metal Contour Plates, Coating Work of Steel Structures, Acceptance of Subitem-works of Steel Structures, and 9 appendixes. The Work of Steel Structures is divided into 10 subitem-works in principle, which are presented in separate chapters respectively. Though the Admittance of Raw Materials and Finished Products is not one of the subitem-works, it is presented in one independent chapter, aiming at emphasizing and enhancing the importance of the admittance inspection of raw materials and finished products and therefore ensuring the construction quality by controlling the quality of the source. Additionally, the Acceptance of Subitem-works of Steel Structures is also presented in an independent chapter in order to provide further convenience for the operation of the acceptance of construction quality.
This Code may be revised where necessary in the future. The information about the revision of any parts of this Code and the revised clauses will be published on the magzine Standardization of Construction.
This Code?€?s clauses highlighted in boldface are mandatory.
