Investigate the control vibration deck cable bridges using System Expansion Joint
ABSTRACT: Damping, characteristics for structure are unknown . also can not, the exact value for damping be determined . These characteristics can be, two earthquakes where,directions the focal and distances are different . In to cable bridge most important element that are cables where the connections are not good , overall the bridge very little damping . Due to the high flexibility cable bridge, these bridges have characteristics of, nonlinear behavior . Also they are apply most important factor is the behavior of large span , And should in a variety be Analysis of static and dynamic , nonlinear behavior. So it is new system recommended , The system abilities include : Tensile control of forces on cables , Vibration control deck , Control tower Deck and torsion control during the aerodynamic force is applied .In this research have been tried, we introduce the type system , position and its application in is bridge and then the modeling of a two-span cable bridge with damper expansion joint between the bridge and without damping systems is investigated comparison . |
