|Description:||Series B T-stubs were cut from a W21 x 93 and were designed for a beam set back of 2 in.
A total of 48 T-stubs were tested individually under cyclic and monotonic loads. The component tests consisted of T-stubs cut from 4 different W-sections and divided into four series labeled A through D. Within each of these different series, parameters such as bolt grade, diameter, gage, and spacing, were systematically varied to study the effects of prying on the tension flange and bearing on the stem. Various configurations of 7/8” and 1" diameter A325 and A490 bolts were used. The four series of T-stubs were further divided into groups based on bolt diameter.
See Tables 4-3 and 4-4, and Section 4.6.3 in the James Swanson Dissertation in the documentation to understand the setup of each group.
The components were subjected to axial loads based on expected beam flange forces in actual connections. The axial loading is a simplification of the actual conditions, since both localized bending and shear forces present in the actual connection were missing in the component tests.
