The objective of this study is to evaluate the location of a failure surface generatrix and the punching shear strength of hollow plat slabs. The main test parameters was the location of a starting position of hollow materials that varied between 1d and 3d, where d is effective depth of slab section. Based on test results, the starting position of hollow materials in plat slabs is recommended to be more than 2d to avoid the reduction of concrete punching shear strength.
