[提要]介紹了開槽墊板施工工藝的特點，并利用有限元法和斷裂力學(xué)原理對應(yīng)用開槽墊板的高層鋼框架節(jié)點的脆斷性能進行了分析。和我國目前采用的施工工藝的比較結(jié)果表明，應(yīng)用開槽墊板的節(jié)點發(fā)生脆性斷裂的可能性要小得多，是。種值得推薦的施工方法。[關(guān)鍵詞]鋼框架 梁柱節(jié)點 開槽墊板The paper introduces characteristics of grooved backup bar and analyses the performance of brittle fracture of steel frame connections using grooved backup bars. The results of analysis indicate that fracture possibility using the technique of grooved backup bars is smaller than the technique we use in china. It is significant to introduce the technique of grooved backup bars to construction of beam-column connections.Keywords: steel frame; beam-column connections; grooved backup bar
