摘　　要：通过九榀钢筋混凝土梁柱偏心节点试件在低周反复荷载下的试验研究 ,探讨了梁柱偏心和梁端水平加腋对节点核芯区抗裂性能的影响 .试验中观测和记录试件的初裂荷载和裂缝的开展与分布 。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 distribution of cracks were measured in the experiment.An equation is developed to calculate crack resistance capacity of eccentric beam column joints.Some suggestions on improving crack resistance of eccentric joints are proposed.

关 键 词：梁柱偏心节点 加腋宽度 抗裂度 抗裂性能
