Behaviour of tall buildings and structures in strong winds: Dynamic properties, response characteristics and vibration mitigation

摘要: This paper presents techniques and instrumentation employed in the measurement of dynamic structural properties tall buildings structures, long-term monitoring their responses strong winds, vibration mitigation systems installed actual structures. The merits limitations these are discussed. Natural frequencies vibration, deflected mode shapes damping values can be determined reliably through measurements on buildings, results provide invaluable validations numerical modelling generalised prediction formulae. improved accuracy processes, coupled with a better understanding building performance monitoring, lead to significant cost savings wind-resistant design construction buildings.
