This paper proposed a dry construction method for RC slab to connect with unbonded PCaPC frame structure, which is considered to extend reuse of structural members after earthquake damage. Then, a static loading test was conducted on unbonded PCaPC frame with RC slab assembled by dry construction method. As a result, the effects of slab on the stiffness and strength of beam were quantitatively grasped, and an evaluation method considering this effect was proposed. In addition, the possibility of reusing RC slab was confirmed by employing residual crack width, which is significant engineering quantity to evaluate repairability performance.
