Abstract
This paper presents the results of tests conducted for beam-column subassemablages having a beam section of H-600×250×12×25 and joined by a method of shop-welding type. A total of 40 specimens were tested, with the type of connection details, type of run-off tabs, method of welding, and loading rate as primary test variables. Major findings include that (1) specimens whose beam-to-diaphragm weld had a weld pass sequence of one path per layer failed early; (2) ductility capacity was generally larger for flux run-off tabs than for steel run-off tabs because of early crack growth observed in specimens with steel run-off tabs; (3) plastic deformation capacity remained relatively unchanged regardless of the type of connection details; and (4) dynamic loading did not reveral visible decrease in plastic deformation capacity compared to quasi-static loading, with a possible reason identified as significant temperature rise observed in dynamic loading.
