This study examines the role of slab stiffness in reinforced concrete structures during seismic events. Typically, slab panels are neglected in structural analysis due to their complex behavior. However, slabs significantly increase lateral load resistance during earthquakes due to their in-plane stiffness. Slabs distribute loads in structures and come in types like ribbed and waffle, used for large spans and high loads. These slabs reduce reinforcement needs and provide stiffer, lighter floors, ideal for areas requiring minimal columns. The study emphasizes uniform distribution of mass, stiffness, and strength to improve earthquake resistance. It also identifies a gap in research on the suitability of these slabs for tall structures, aiming to evaluate their performance and assess their cost, stability, and strength advantages.
