This is the accepted version of the paper.This version of the publication may differ from the final published version. In view of the grave socioeconomic consequences of earthquake damage to bridge structures, along with their critical role in modern and older road and rail networks, this article attempts to identify and summarise the current trends in the use of semi-active control technology in bridge engineering, as an enhanced seismic response control solution, combining increased adaptability and reliability, compared to passive and active schemes. In this context, representative analytical and experimental studies, as well as some full-scale applications of semi-active control devices are first reviewed and a brief description of relevant benchmark studies is subsequently presented, with a view to serving as a point of reference for further research and development. A framework of performance-based control principles aiming at the aforementioned objectives is finally set forth. Permanent

Abstract.A conglomerate, composed of granular materials encapsulated in a tight, flexible envelope, and submitted to an internal underpressure, changes its properties in the function of the vacuum range. The underpressure level, controlled by a vacuum pump, enables controlling the behavior of such a medium. This particular ability could be useful in some specific applications.In this paper authors consider different mathematical formulations for description of nonlinear properties of Vacuum Packed Particles. Basing on various experimental tests such as compression tests with different strain rates or stress relaxation tests the authors discuss the encountered problems in defining a global rheological model for considered extraordinary materials.

A seat suspension with a rotary magnetorheological damper for heavy duty vehicles AbstractThis paper presents the development of an innovative seat suspension working with a rotary magnetorheological (MR) fluid damper. Compared with a conventional linear MR damper, the well-designed rotary MR damper possesses several advantages such as usage reduction of magnetorheological fluid, low sealing requirements and lower costs. This research starts with the introduction of the seat suspension structure and the damper design, followed by the property test of the seat suspension using an MTS machine. The field-dependent property, amplitudedependent performance, and the frequency-dependent performance of the new seat suspension are measured and evaluated. This research puts emphasis on the evaluation of the vibration reduction capability of the rotary MR damper by using both simulation and experimental methods.
