Experimental Study on Two-Step Concrete Corbels with Several Interface Conditions

Table 1

Summary of geometry and interface surface conditions of the tested specimens.

Specimen ID	Dimensions of the section of corbel () (mm)	fcu (MPa)	Interface surface condition
M1	200 × 300	32	Control, monolithically
M2			Contact surface mean roughness depth = 4 mm
M3			Contact surface mean roughness depth = 8 mm
M4			Using epoxy adhesive without surface roughness
M5			Implanted main steel reinforcement and vertical stirrups
M6			Implanted main steel reinforcement only

Note. b, width of corbel; h, height of corbel.
