Decision Making to Optimize Two-Way Slabs Thickness for Sustainable Development in Structural Design

This study investigates the minimum thickness requirements for two-way slabs, focusing on their effectiveness in controlling deflection under service loads. Using finite element analysis in ANSYS Workbench, a parametric study was conducted to assess the impact of various parameters, including slab thickness, span lengths, and applied loads, on the overall structural response. The research aims to determine whether the provisions outlined in ACI 318 adequately satisfy the maximum allowable deflection limits established by the code. The results indicate that while the minimum thickness requirements provide a baseline for design, additional considerations, such as concrete material properties and reinforcement ratios, are necessary to ensure optimal performance. The findings contribute valuable insights into improving design practices for reinforced concrete structures, highlighting the need for more nuanced guidelines that account for various influencing factors.
