Abstract

For long-span and light floor systems, the stiffness and damping values are usually small. In that case excessive vibration may occur due to human activities, such as walking, dancing, aerobics, jumping, and audience participation in music concert, and mechanical equipment operation such as HVAC systems, washing machine, and machines operation. Such disturbances affect human comforts as well as floor performance. In order to reduce the vibration of the floor, mechanical absorbers are utilized. The floor is modeled as simple distributed parameter system with the absorber is attached at a particular point on the floor systems. The equation of motion is derived by utilizing the Hamilton’s principle. The resulting equations of motion involve normal coordinate, as well as, physical coordinates at the attachment of the absorber. Absorbers with active control strategies are discussed in order to reduce the vibration of the structure. Simulation results show that the vibration of the floor system can be reduced such that increasing the human comfort and performance of the floor system.
