Abstract: High-performance control systems (HPCS) are sophisticated vibration-mitigation devices that include active, semiactive, and hybrid systems. HPCS leverage feedback mechanisms to dynamically adjust the damping force in ...

Abstract: Performance-based design (PBD) is becoming a benchmark approach for design and performance assessment of civil structures because it facilitates communication between stakeholders and design professionals with decision ...

Abstract: Supplemental damping devices, including passive, semiactive, and active systems, can be employed to reduce vibrations caused by various hazards. This paper examined tuned liquid column dampers (TLCDs), a specialized type ...

Abstract: This paper investigates the performance of a novel semiactive damping device at mitigating nonsimultaneous multihazard loads. The device, termed modified friction device (MFD), has been previously proposed by the authors. ...

Abstract: High-performance control systems (HPCSs), including active, hybrid, and semiactive control strategies, can perform over a wide excitation bandwidth and are therefore good candidates for multihazard mitigation. However, the ...

Abstract: Structural health monitoring of civil infrastructures is a difficult task, often impeded by the geometrical size of the monitored systems. Recent advances in conducting polymers enabled the fabrication of flexible sensors ...

Abstract: Fatigue cracks are critical structural concerns for steel highway bridges, and fatigue initiation and propagation activity continues undetected between physical bridge inspections. Monitoring fatigue crack activity between ...
