Details of the test specimens.

Specimen	Infilled concrete	Web anchorage plates	Thickness of the RC slab (mm)	Reinforcements
SBJ1	C30	Stiffening	NA	NA
CBJ1	C30	Nonstiffening (VAR)	100	10 mm@100
CBJ2	NA (VAR)	Stiffening	100	10 mm@100
CBJ3	C30	Stiffening	120 (VAR)	10 mm@100
CBJ4	C30	Stiffening	100	10 mm@100

Note. 10 mm@100 denotes reinforcements of 10 mm in diameter and 100 mm in spacing; C30 is the grade of the concrete in the Chinese standard; CBJ denotes a composite beam joint; SBJ denotes a bare steel beam joint.
