This paper describes the performance of lap splice of D16 reinforcing bar on strain hardening cementbased composite(SHCC). The specimens had two types of compressive strength (30MPa and 100MPa). Both types strengthened by hybrid fibers with polyethylene fiber(PE) and steel fiber(SF) and had 60 percent lap splice length of KCI code. The experiment evaluated tensile performance and cracking behavior of lap spliced specimens. It was found that high-strength SHCC had lower tensile strength than normal-strength SHCC. Comparison tensile performance of lap splice between high-strength SHCC and normal-strength SHCC implies that development of huge initial autogenous shrinkage of high-strength SHCC affected the lap splice performance.
