[提要] 提出了結(jié)點剛域長度不僅與結(jié)點結(jié)構(gòu)布置而且與結(jié)點受力狀況有關(guān)的概念，推導出T型結(jié)點剛域長度的修正公式，并將其應用在框筒的平面框架子結(jié)構(gòu)法中，得到了令人滿意的結(jié)果。
[關(guān)鍵詞] 結(jié)點剛域長度 框筒結(jié)構(gòu) 平面框架子結(jié)構(gòu)One new conception is proposed that the length of stiffness zone of a joint is affected by its internal force, as well as its layout.A formula to obtain such a length of T-shaped intersection joint has been derived, which is applied in plane frame substructure program to analyse a 30-storey frame tube structure and the satisfactory result is achieved.
Keywords: stiffness zone length; joint; frame-tube structure; plane frame substructure
