by The announcement of the Ministry of Housing and Urban Rural Development on the issuance of the Guidelines for the Dimensions of Main Members of Steel Structure Residential Buildings In order to implement the Guiding Opinions of the General Office of the State Council on Vigorously Developing prefabricated building (GBF [2016] No.
71), carry out green building initiatives, and further promote the development of steel structure residential buildings, we have organized the preparation of the Guidelines for the Dimensions of Main Members of Steel Structure Residential Buildings, which are hereby issued.
Full text of the attachment: The “Guidelines for the Dimensions of Main Components of Steel Structure Residential Buildings” catalog is divided into 6 chapters and 3 appendices, including: 1.
Overview; 2.
Dimensions of beam components; 3.
Dimensions of column components; 4.
Dimensions of supporting components; 5.
Dimensions of low rise cold formed thin-walled steel components; 6.
Connection node size.
1 Overview 1.1 Purpose and Scope of Application 1.1.1 In order to implement national technological and economic policies, the standardization concept is integrated into the entire process of steel structure residential design, production, construction, operation and maintenance, guiding steel production enterprises, design units, and production enterprises to coordinate and unify the commonly used cross-sectional shapes, sizes, and lengths of components, promoting component standardization, improving efficiency, saving costs, and improving the overall construction level of steel structure residential buildings, Develop this guide.
1.1.2 This guide is applicable to the factory production and design selection of hot-rolled steel components, cold-formed steel components, and their combination components for steel structure residential buildings, including regulations on the coding rules, common lengths, common cross-sectional forms and sizes, connection nodes, etc.
of components.
1.1.3 This guide applies to beams, columns, supports, and components in low rise cold-formed thin-walled steel structures in steel residential buildings.
1.2 Basic regulations 1.2.1 The commonly used cross-sectional form, size, and length of steel structure residential components should be determined based on the frequency of use, as well as the principles of economy and applicability, and should comply with the relevant provisions of the current national standard “Building Modular Coordination Standard” GB/T50002.
The determination of the commonly used cross-sectional form, size, and length of steel structure residential components should not only be coordinated with the building functional space, structural system, peripheral protection system, interior system, equipment and pipeline system, but also with the production, transportation, construction and installation of components.
1.2.3 The components of steel structure residential buildings should choose the commonly used cross-sectional forms, dimensions, and lengths of the components provided in this guide.
Designers should still comply with the current national standards when selecting the section of the components listed in this guide
