[提要]  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，探讨了粱柱偏心和粱端水平加腋对节点核芯区抗裂性能的影响。试验中观测和记录了试件的初裂荷载和裂缝的开展与分布，提出了偏心节点抗裂度计算的建议公式和改善偏心节点抗裂性能的一些建议。

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
