Performance Study for T-Stub Considering the Bending Capacity of Bolt

The bending capacity of the beam end-plate or the column flange and the tensile property of the bolt could be expressed by an equivalent t-stub model. In this paper, ten groups of different sizes of T-stub are designed for monotonic loading test. The accurate element models are established for comparable study with the experimental result. The stress distribution and deformation characteristics of the T-stub and bolts are determined. A theoretic formula of tensile stiffness for T-stub is derived, it is presented that the calculation results are consistent with the tests.
