Abstract
The behavior and analysis of bolted flange plate connections in rectangular hollow section tension members is considered, with the bolts along only two opposite sides of the rectangular hollow section. Sixteen tension tests on such connections are described, and it is shown that one can, by selecting specific connection parameters, fully develop the tensile resistance of the member by bolting along only two sides of the tube. The application of traditional prying models developed for T‐stubs is found to not correlate well with the test results, so analytical models based on plastic theory are consequently proposed, and these are found to predict the failure mode and the joint ultimate strength to within 6%.
