（1 同濟(jì)大學(xué)建筑工程系 上海 200092； 2 合肥工業(yè)大學(xué)建筑工程系 230009）[提要] 通過九榀鋼筋混凝土梁柱偏心節(jié)點試件在低周反復(fù)荷載下的試驗研究，探討了粱柱偏心和粱端水平加腋對節(jié)點核芯區(qū)抗裂性能的影響。試驗中觀測和記錄了試件的初裂荷載和裂縫的開展與分布，提出了偏心節(jié)點抗裂度計算的建議公式和改善偏心節(jié)點抗裂性能的一些建議。
[關(guān)鍵詞] 梁柱偏心節(jié)點 加腋寬度 抗裂度計算 抗裂性能Nine specimens of eccentric beam-column connections were tested under reversed cyclic loading. Experimental and analytical studies were carried out to investigate the influence of eccentricity and spread-ended beam width on crack resistance in the core area of eccentric joints. The first crack load and the development and distribution of cracks were measured and recorded in the test.The equation is given for computing crack resistance capacity of the eccentric beamcolumn joints, and some suggestions are proposed about improving crack resistance of the eccentric joints.
Keywords: eccentric beam-column joints; spread-ended beam width; crack resistance capacity; crack resistance
