Strength, rigidity, capacity of elongation, bond stress-slip relations etc. of grout-filled coupling steel sleeves with interior projections under cyclic loads were investigated. Experimental variables adopted in this study were development length of reinforcing bars, compressive strength of grout as filler materials and magnitude of cyclic loads. Following main conclusions are obtained (1)Mechanical performance of the splices subjected to cyclic bad is improved significantly with increase in development length of reinforcing bars and compressive strength of grout (2)Assumption of constant bond stress between grout and reinforcing bars in the splices leads equations to estimate strength and failure types of the splices.
