Abstract
Waffle panels have attracted the attention of many building designers due to their numerous advantages. The punching shear strength and performance of these panels are some of the key determining factors in their design process. Due to the geometrical difference between the lattice area and the solid area around the column in this type of roof, the dimensions of the solid area can be a crucial factor in the punching shear performance of this slab. In this study, 10 waffle plates of 2300 x 2300 mm were meticulously modeled and analyzed using ABAQUS software. Samples with and without openings were examined in two separate groups to provide a comprehensive analysis. The punching shear performance of the plates was thoroughly examined in both groups and finally, the punching shear strengths determined from the software and the ACI 318-19 code were compared. The results indicate that by increasing the area of the solid zone around the column, the punching shear capacity increases, and the ductility changes. Additionally, the placement of openings on the panels reduces the punching shear capacity and ductility. However, the dimensions of the solid area do not seem to affect the strength of the impacts caused by the openings, providing essential insights for design considerations.
