Abstract
Numerous welded steel moment-resisting connections failed by brittle fracture during the Northridge, California earthquake of January 17, 1994. The results of tests of three full-scale specimens of a typical interior moment-resisting connection, one a bare steel specimen and two with a composite floor slab, along with a corroborating computational investigation, are described in this paper. The preliminary results indicate that the strains near the bottom flange of the specimens with a slab are significantly larger than those near the top flange. These results, which show evidence of both brittle and low cycle fatigue fractures, help to explain the predominance of bottom flange failures, and they indicate that changes may be required in design codes which currently ignore unintended composite floor action.
