Dept. of Architectural Engineering, College of Engineering, Hanyang University, Seoul 133-791, KoreaABSTRACT This paper presents the shear capacities of biaxial hollow slab with donut type hollow sphere. Recently, varioustypes of slab systems which can reduce self-weight of slabs have been studied for increasing constructions of taller and larger build-ing structures. A biaxial hollow slab system is widely known as one of the effective slab system, which can reduce self-weightof slab. According to previous studies, the hollow slab has low shear strength, compared to solid slab. Also, the shear capacitiesof biaxial hollow slab are influenced by the shapes and materials of hollow spheres. However, the current code does not providea clear computation method for the shear strength of hollow slab. To verify the shear capacities of this hollow slab, one-way sheartests were performed. Four test specimens were used for test parameters. One was conventional RC slab and others were hollowslabs. The test parameters included two different shapes and materials of plastic balls. The shape parameters were donut and non-donut forms and the material parameters were general plastic and glass fiber plastic. The results showed that the shear strengthsvaried depending on hollow shapes and materials used in the slab.Keywords : biaxial hollow slab, hollow sphere, shear strength, experimental study, flat plate slab
