Tests of Full‐Size Gusset Plate Connections

Abstract

The paper presents an evaluation of the behavior and strength of gusset plates on the basis of an experimental investigation of full‐scale diagonal bracing connections. Sugh connections commonly occur in heavy industrial structures, for example. The evaluations are based on analyses of load and deformation data that were generated during the tests, including the failure patterns for the plates. A total of six tests were run, using three bracing member orientation angles. The results are correlated with analytical studies, with special emphasis on recent finite element work. The results are found to be in reasonable agreement Current design practices are discussed briefly; some of the methods are shown to be in acceptable agreement with the tests. It is shown that plate boundaries, plate buckling, and related out‐of‐plane bending phenomena have significant effects on the plate behavior. Recommendations for additional work are also made.
