Abstract: In recent dynamic problems dealing with high-frequency excitations, such as ultrasonic vibrations, a proper representation of rods transmitting kinetic energy from the interface attached to the ...

Abstract: This study focuses on how to determine an optimal radius minimizing the bending strains of vertical, cylindrical fixed-head piles embedded in a homogeneous elastic stratum in soil-pile-structure systems where the kinematic ...

Abstract: Using digital IR data obtained by SMS I satellite, the large-scale behavior of convective activity was investigated over the tropical Atlantic within the GATE area. Spectral analysis has revealed the existence of two ...

Abstract: This paper describes the correspondence of planetary wave activity between the troposphere and the stratosphere during the Northern Hemisphere winter from December 1981 to March 1982 using Elliassen?Palm E;P) flux diagnostics. ...

Abstract: A rule-based control algorithm for active tuned mass dampers (TMDs) is proposed. First, perturbation solutions of the linear quadratic regulator (LQR) feedback gains for the active TMD system are derived. Using these ...

Abstract: A design method of tuned mass dampers (TMDs) for structures with bilinear hysteresis subject to harmonic excitation is proposed. Conventional TMDs fail to control a bilinear structure as the equivalent natural frequency ...

Abstract: This study presents a methodology to make a simple equivalent model of frequency-dependent impedance functions of soil-structure interactions using a frequency-independent spring and dashpot, together with a proposed element ...

Abstract: This study presents formulas for determining structural properties by which the maximum ductility factors and strain energies stored in elastic-perfectly plastic springs composing a structural system subjected to static ...
