A summary of the strength and deformation capacities of the test specimens.

Specimen	Shear strength (kN)		Displacement (mm)			Strength ratio	Ductility ratio; ( or )	Failure mode
	Yield	Max.	Yield	Max.	Ultimate
SF-0	240	278	14.0	17.5	30.0	1.0	1.25	Shear
SF-R1	413	464	32.0	44.0	120.0	1.67 (67%)	3.75	Flexure
SF-R2	515	555	46.7	56.3	118.0	2.0 (100%)	2.53	Flexure

The strength ratio is defined as the maximum load of the SF-R1 or SF-R2 specimens divided by that of the SF-0 specimen, which indicates strengthening effects in terms of shear strength capacity compared with control SF-0 specimen.
/ is the ductility ratio for shear failure of specimen SF-0, where is the maximum displacement and is the yield displacement.
is the ductility ratio for the flexural failure specimens SF-R1 and SF-R2, where is the ultimate displacement and is the yield displacement.
