Cable Force Identification With Unknown and Variable Elastic Boundary Supports: Theory and Validation

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The vibration method is widely used for identifying cable tension. However, the boundary conditions of cables in structures are often not ideally hinged, resulting in a significant error in identifying cable forces. To precisely determine the stress state of cables, this paper proposes a methodology for cable force identification with unknown and ...

Fast evaluation on the fatigue level of copper contact wire based on laser induced breakdown spectroscopy and supervised machine learning for high speed railway

High Voltage, Volume 9, Issue 6, Page 1302-1310, December 2024.
Abstract High‐strength copper contact wire is of great significance to the electrified railway power supply system, which constantly provides electric power to the trains during operation. However, contact wire is subject to pressure, vibration, and natural forces such as wind, rain, ice, etc.

Experimental investigation of dowel action in reinforcing bars using refined measurements

Structural Concrete, Volume 25, Issue 4, Page 2732-2758, August 2024.
Abstract In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either explicitly in mechanical models or implicitly in empirical relationships.

Robustness improvements for 2D reinforced concrete moment resisting frames: Parametric study by means of NLFE analyses

Structural Concrete, Volume 25, Issue 1, Page 9-31, February 2024.
Abstract This study develops a 2D computational parametric analysis of ordinary reinforced concrete (RC) frames, located in seismic zone, with the aim to evaluate some design suggestions with respect to their effectiveness in increasing the structural robustness.

Experimental study and numerical analysis of progressive collapse resistance of composite frames [PDF]

, 2013
A partial damage caused by an abnormal load could trigger progressive collapse of high rise buildings which may lead to terrible casualties. However, in the process of column failure, "catenary action" plays an important role in redistributing the ...

Semiactive Control of Nonlinear Parametric Vibration of Super‐Long Stay Cable in Cable‐Stayed Bridge Installed with Magnetorheological Fluid Damper

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
As the stay cables of cable‐stayed bridges become longer, parametric resonance with a large amplitude is more easily triggered, which becomes a vibration hazard of super‐long stay cables. An increasing number of practical applications of vibration mitigation on stay cables demonstrate that vibration control strategies can effectively facilitate hazard ...
