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。试验中观测和记录了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 development and distribution of cracks were measured and recorded in the test.The equation is given for computing crack resistance capacity of the eccentric beam column joints,and some suggestions are proposed about improving crack resistance of the eccentric joints.
