Comparison of Various Methods for Determining Dynamic Behavior of Voided Floor Slabs

Floor slabs are essential load-bearing components in buildings, and their dynamic behavior plays a crucial role in their serviceability limit state. In residential or office buildings, understanding the dynamic behavior of slabs is vital for ensuring the well-being and comfort of occupants. In buildings like medical facilities or laboratories, which contain sensitive equipment, it is equally important to assess dynamic behavior to prevent vibration-induced damage to machinery. Therefore, it is imperative that the dynamic properties of floor slabs are evaluated and considered in the design stage. As there are various viable methods to calculate these properties, this paper will focus on the most widely used methods and compare the effectiveness of their results in representing the real-world dynamic behavior of a voided floor slab via a case study. As the results presented in this paper prove, simplified calculation methods are capable of providing accurate results while being time and resource-saving.
