Abstract
A series of tests on single angle connections have been performed to provide background
information for a PhD research project underway at the University of New Brunswick. Twelve
single angle connections with one leg welded to a column flange and the other bolted to a
beam web were subjected to pure shear. The parameters under consideration are the angle
thickness and the bolt line gauge distance.
The stiffness of a single angle connection increases with angle thickness and shorter gauge
distances. Yielding occurs at higher load levels for stiffer connections, resulting in smaller
deflections. The two limit states that were observed included bolt shear fracture and net section
failure of the connecting angle. The ultimate capacity of the connection was also determined to
be on average, twice as much as the calculated design values. In addition, the test setup used in
this study proved to be effective in subjecting simple confections to pure shear, in addition to
being a simple an economical setup.
