초록

This paper presents an experimental investigation on maximum crack spacing of donut type biaxial hollow slab for theserviceability. According to the existing investigation, flexural capacity showed similar test results with general RC slab.However, in case of flexural crack spacing, it showed spacious distribution than general RC slab. Therefore, flexural crackspacing of this slab considers that it will be judged by average bond stress, and this paper verification on flexural crackspacing of the existing bending specimens were performed through pullout tests. Validity was verified through maximum crackspacing through the calculated average bond stress at pull-out tests and existing bending specimens.
