摘要

This study investigated the bond characteristics of embedded deformed bar in biaxial hollow slabsrnwith donut type hollow shapes. The hollow shapes are consist of the radius of curvature and thernhole diameter. In biaxial hollow slabs, bond capacity is different from general RC slab because thernvoid of slab might reduce the area of the deformed bar surrounding concrete. Therefore, FEMrnanalysis was performed to find out the effect of hollow shape on the bond characteristics ofrndeformed bar. Bond characteristics of biaxial hollow slabs were investigated according to the bondrnregion of hollow shape using the nonlinear finite element program LUSAS. The main parameterrnwas the distance between void and deformed bar. To investigate the bond characteristics, hollowrnslab was divided into 3 sections according to the distance between void and deformed bar such asrnsufficient region, transition region and insufficient region.
