With the aim of exammmg shear stress transfer mechanism in construction joints of concrete structures, shear tests which compare the specimens of construction joint having different degrees of roughness with unjointed ones were conducted. As the result, it has become clear that the shear transfer mechanism is subdivided into approximately four stages: before crack initiation, crack propagation stage, transition stage, and interlocking stage, and that the difference of shear transfer between construction joints and unjointed specimens is caused by the difference of behavior in the transition stage. Futhermore, the existence of shear softening in the crack propagation stage was shown by the tests.
