Abstract
Dealing about dynamic behavior of concrete structures, precast elements are subjected to several loading conditions, from their manufacturing, transport, assembly, connection and finally to service. Prestressing technique is often applied in precast elements, so the influence of prestressing forces on dynamic parameters must be considered. Also typical double-T panels and hollow core slabs were analyzed by Finite Element Method (ANSYS® software) and analytical and numerical results were compared. A discussion of the results about the Service Vibration Limit State is made. This work also presents an experimental study on a reinforced concrete beam provided with external prestressing tendons. The goal of this study was to demonstrate dynamic tests to characterize dynamic parameters and to discuss vibration control. Keywords: Precast concrete. Prestressing. Floors. Dynamic analysis.
