摘　　要：提出了一种基于挠度法的节点刚度测试新方法。这种方法从节点刚度的基本定义出发,认为梁上某点测得的挠度值实际上是由两部分组成的,一是因梁的理想弹性弯曲产生的,二是因节点域变形导致梁发生转动而产生的。通过挠度测试,可以求出因节点域变形导致梁发生转动而产生的挠度值,进而可以得到梁柱夹角发生的改变量。It is put forward that a new method of testing steel framework joints stiffness, deflection method.From the basic definition of the joints stiffness,it considers that the deflection of a certain point of the beam consists of two parts,one is produced by the beam′s ideal elastic bend,the other is produced by the deformation of joint field.By the deflection test,the deflection produced by the deformation of joint field can be gained,accordingly,the change in the included angle that the beam axis relative to the pole axis can be gained too.
