摘　　要：研究了H形梁和H形柱弱轴单板简支连接的受力性能。为了研究节点连接对于H形柱腹板的影响以及单板在节点受力过程中扭转问题,对H形梁与H形柱腹板的单板简支连接进行了试验研究。提出了节点部位H形柱腹板的抗弯和抗冲剪承载力计算方法;给出了提高节点单板抗扭转能力的构造要求。最后将理论计算、试验和有限元分析结果进行对比,验证了计算方法的准确性。This paper presents a study on the behavior of minor-axis H-shaped beam-to-column connections with single shear plate.Experimental studies were firstly carried out on single shear plate connections to evaluate the influence of this connection to column web as well as the distortion occurred on the single shear plate.Based on the test results, a simplified approach was proposed for predicting the ultimate bending and shear capacity of column web in H-shaped beam-to-column connections,and prescriptive specifications were given to enhance the distortion bearing capacity of single shear plate connections.Finally,the validity of the proposed approach was established through comparing predictions with results from test and finite element analysis.
