摘要
本文以作者完成的钢筋混凝土框架中间层端节点足尺试件的静力试验结果为主要依据，同时参照已收集到的国内外其它试验结果，对框架中间层端节点中梁负弯矩筋直角弯折锚固端的承载力进行了分析，对国家标准《混凝土结构设计规范》（ＧＢＪ１Ｉ－８９）中关于这类锚固端水平锚固长度的规定作了进一步验证，对这类锚固端的设计概念和设计规定提出了改进建议。
On the basis of the results of static tests of the full-scale subassemblage of exte-rior joints in reinforced concrete frames,and with reference to other experimental results of homeand abroad.This paper analyses the load-earrying capacity of the anchorage end of 9O-degree bentbeam reinforcement in the exterior joints,verified the horizontal development length of this kind ofanchorage end Specified in the state standard' Concrete Structure Design Code'',and proposes im-provements for the design concrete and specification for this kind of anchorage end.
