Modern architecture and construction design, leading floor system to have longer spans, lighter weight, and lower damping. However, it can cause a floor system to have excessive vibration. Vibration on the floor system is the second most frequent source of complaints from building occupants. Hollow Core Slab (HCS), are precast concrete floor elements widely used nowadays in multiple construction buildings. HCS has the advantage of lightweight and prestressed that makes the possibility to create long-span floors that are in line with modern construction design. In this study, we research the HCS floor's vibration behavior and its compliance with the minimum standards for serviceability criteria. The test is carried out by giving an impact loads using the impact test method. The accelerometer sensor used to measure the vibration that occurs. The test is carried out on two treatments, first on simply supported HCS, and the second is HCS supported to the beam with a shear connector. The test location is on a two-story parking building with several variations in the floor dimension, and the HCS thickness is 150 mm. This research shows that all of the floor's natural frequency meets the minimum frequency requirement, 3 Hz. Some floor's natural frequency had gotten in the human body's sensitive frequency range 4-8 Hz. The majority of the slabs have low-frequency floor categories. The natural frequency tends to be higher if the span of floors is smaller, and the natural frequency tends to be higher on HCS supported to the beam using a shear connector.
