Buildings, Equipment and Pipe Networks Vibration and Noise Control using SERB – SITON Devices
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2011, Vol 8, Issue 1
Abstract
Buildings, equipment and pipe networks, herein below called ”structures”, are affected by the dynamic actions of earthquake, shocks and vibrations type, herein below called ”excitations”. The repeated action of excitations on structures most often lead to important built-up of kinetic and potential energy in structures. This leads to an increase of the amplitude in accelerations and displacements of structures accompanied by the occurrence of damages or destroy. The paper presents the performances of SERB-SITON isolation and telescopic devices used to protect buildings, equipment and pipe networks against dynamic actions. For large-size buildings such as nuclear power plants, old buildings, churches, bridges, etc., SERBSITON isolation devices with a very small and adjustable stiffness installed under the structure on any horizontal direction, are presented. For reinforced concrete or metal framework buildings such as high buildings, industrial halls, towers, etc., SERB-SITON telescopic devices with controlled stiffness and damping large force inclusively are presented. For equipment and pipe networks, SERB-SITON supports that are capable to overtake large permanent loads with relative displacements on two directions for thermal displacements, and also capable to elastically overtake and damp dynamic actions, are presented. In order to reduce the propagation of the noises and to absorb them, the SERB – SITON panels are presented.
