Shear Failure of RC Dapped-End Beams

Table 2

The compressive strength and reinforcement details.

Specimen		Concrete type			HR		NFR	BMFR
	MPa		mm	mm	mm	MPa	mm	mm	MPa
DEB-1	27	NSC	—	—	—		310	310	470
DEB-2	27; 79	NSC; ECC	—	—	—		310	310

U = U bar (2 legs); St = stirrup (2 legs); = nib horizontal reinforcement, = nib vertical reinforcement; HR = = hanger reinforcement; NFR = nib flexure reinforcement; BMFR = beam main flexure reinforcement; = concrete compressive strength; and = yield stress of reinforcement.
