（中國建筑科學研究院，北京100013）[摘要] 對《空間網格結構技術規(guī)程》的編制情況進行了系統(tǒng)的介紹。規(guī)程編制的主要工作與內容是將原《網架結構設計與施工規(guī)程》JGJ 7 -91與《網殼結構技術規(guī)程》JGJ 61 -2003從技術上合二為一，并與新頒布的有關規(guī)范標準協(xié)調一致；增加了立體管桁架與張弦立體拱架、預應力網格結構計算與節(jié)點、鑄鋼節(jié)點、銷軸式節(jié)點等方面目前國內空間網格結構發(fā)展方面一些新的技術與內容；以網殼規(guī)程中焊接空心球節(jié)點設計承載力公式為基礎，給出了改進的空心球節(jié)點拉彎、壓彎設計承載力公式；反應了最新空間網格結構方面的構造設計與施工技術要求。

( China Academy of Building Research, Beijing 100013, China)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.
