（清華大學土木工程系 北京 100084）[提要] 介紹了兩個鋼筋混凝土巨型框架梁柱節(jié)點的試驗，研究了節(jié)點區(qū)不開洞、梁端破壞的梁柱節(jié)點的破壞過程、破壞形態(tài)和受力性能，用極限分析建立了巨梁整體受彎承載力的計算方法。
[關(guān)鍵詞] 鋼筋混凝土 巨型框架 梁柱節(jié)點 極限分析Experiment on two reinforced concrete beam-column joints of mega-frame is intruduced. Failure procedure, failure pattern and mechanical behaviour of the joint are studied. The calculation method of the overall flexural strength of mega-beam is established by limit analysis.
Keywords: reinforced concrete; mega-frame; beam- column joint; limit analysis
