[摘要] 对《空间网格结构技术规程》的编制情况进行了系统的介绍。规程编制的主要工作与内容是将原《网架结构设计与施工规程》JGJ 7  -91与《网壳结构技术规程》JGJ 61 -2003从技术上合二为一，并与新颁布的有关规范标准协调一致；增加了立体管桁架与张弦立体拱架、预应力网格结构计算与节点、铸钢节点、销轴式节点等方面目前国内空间网格结构发展方面一些新的技术与内容；以网壳规程中焊接空心球节点设计承载力公式为基础，给出了改进的空心球节点拉弯、压弯设计承载力公式；反应了最新空间网格结构方面的构造设计与施工技术要求。

Abstract: This paper systematically introduces the development process of¨Technical Specification for Space Frame Structures" which is integrated from the original two specifications for "Design and Construction Specification, for Space Frame Structres" (JGJ 7 - 91) and "Technical Specification for Latticed Shell" (JGJ 61 - 2003) in compliance with recently - published codes.  Some newly - develop technologies applied in space latticed structures, such as spatial truss, latticed arch string structure, prestressed space latticed structure, cast steel joint, pin axis joint have been added to the specification. Based on "Technical Specification for Latticed Shell", the formula of load bearing capacity has been improved for welded hollow spherical node. The up - dated technical requirement for detailing design and construction of space latticed structures have been set out.
