Flat slab systems in reinforced concrete structures present a critical issue related to punching shear, particularly under fire conditions. This study conducts a parametric analysis to numerically assess the behavior of slabs exposed to high temperatures, using a 3D Finite Element model in ABAQUS and the Concrete Damage Plasticity (CDP) constitutive model. Key factors such as temperature and the thermo-mechanical properties of concrete and steel are varied across different thermal scenarios. The numerical results highlight the influence of each parameter on the structural response and their role in the global failure mechanism under extreme thermal conditions.
