The specimens represented a subassemblage including a one-story high column between midheight of the two adjacent stories and a half span beam. One specimen (RBS-QCA) had reduced beam section with quarter circular weld access hole. The beam web was bolted to a shear tab which welded to the column flange. The other specimen (WUF-W) was designed without trimming the beam section but with weld access hole details as specified in AWS. The beam web of this specimen was welded to the column flange via a completely join penetration weld. The test results of the specimen RBS-QCA demonstrated that this specimen achieved 5% rad story drift angle with plasticity concentrated on the reduced beam section. Although minor cracks occurred at the tip of the beam flange near the penetration groove weld and the root of the weld access hole, the cracks did not propagate. Local buckling of the beam flange at the reduced section was occurred and led to minor strength deterioration. The specimen WUF-W reached 5% rad story drift angle also. Plasticity of the beam occurred near the beam-to-column interface. Minor cracks were observed at the tip of the beam flange near the penetration groove weld. With the AWS weld access hole details, no cracks occurred in the region of the weld access hole. Using either the reduced beam section or AWS weld access hole, the specimens exhibit significant, reliable strength and ductility.
