Abstract: A three-dimensional dynamic finite element model is established for the Tsing Ma long suspension Bridge in Hong Kong. The two bridge towers made up of reinforced concrete are modeled by three-dimensional Timoshenko beam ...

Abstract: A nonparametric identification method for nonlinear hysteretic systems is presented. Making use of the Duhem hysteresis operator, the multivalued relationship of hysteretic restoring force with respect to displacement and ...

Abstract: The present study involves two aspects associated with the steady‐state performance of the versatile Bouc‐Wen hysteretic model. First, influence of the model parameters on steady‐state responses and hysteresis loops of the ...

Abstract: The parametric approach to eliminating the temperature-caused modal variability in vibration-based structural damage detection requires a correlation model between the modal properties and environmental temperatures. This ...

Abstract: A fatigue reliability model which integrates the probability distribution of hot spot stress range with a continuous probabilistic formulation of Miner’s damage cumulative rule is developed for fatigue life and reliability ...

Abstract: Vibration mitigation of stay cables in cable-stayed bridges using oil dampers was experimentally investigated with scaled model cables and oil dampers. The increased cable modal damping ratios attributed to oil dampers ...

Abstract: This study focuses on how to exploit long-term monitoring data of structural strain for analytical modeling of multimodal rainflow-counted stress spectra by use of the method of finite mixture distributions in conjunction ...

Abstract: False-positive or false-negative damage may be signaled by vibration-based structural damage detection methods when the environmental effects on the changes of dynamic characteristics of a structure are not accounted for ...

Abstract: The present study is intended to develop a new method for analyzing nonlinear stochastic dynamic response of the Preisach hysteretic systems based on covariance and switching probability analysis ...

Abstract: A new method for analyzing nonlinear steady-state dynamic response of three-dimensional sagged stay cables subject to arbitrary periodic excitation is proposed in this paper. Firstly, the nonlinear ...
