Abstract: Effects of a tuned mass damper on the modal responses of a six-story building structure are studied first to demonstrate the damper's ineffectiveness in seismic applications. Multistage and multimode tuned mass dampers are ...

Abstract: New criteria for decoupling of primary-secondary systems have been recently proposed by the first writer. They are defined by a limited variation of the maximum transfer function of a secondary system that is connected to ...

Abstract: Two distinct groups of bond models were developed on the basis of dominant concrete splitting and rebar–concrete interfacial failures, respectively. Their accuracy highly depended on the specific test data sets selected ...

Abstract: A new perturbation method is developed to solve any eigenvalue equation of the form

Abstract: A new control algorithm is proposed in this paper to control the responses of a seismically excited, nonlinear 20-story building with piezoelectric friction dampers. The passive friction damping mechanism is used for ...

Abstract: This paper presents a recursive Hilbert-Huang transform method for the time-varying property identification of shear-type buildings under base excitations. To overcome nonorthogonality and modal perturbation issues, all ...

Abstract: The concept of power flow, which has been found to be a powerful tool in the dynamic analysis of complex systems with conservative connecting elements, is extended to the case of nonconservatively ...

Abstract: Exact solutions are presented for the mean-square responses of a class of complex structure-equipment systems under dynamic loads. The complex systems consist of an

Abstract: A condensation procedure for the coupled analysis of multidegree‐of‐freedom primary‐secondary (PS) structural systems is developed based on energy principles. It provides a simple and consistent approach to the response ...

Abstract: Bridges have recently been exposed to an increasing number of natural hazards such as earthquakes and tsunamis. These extreme events have resulted in transverse offsets, overturning moments, and even dropping-off of ...
