Research on Catenary Action of Frame Structure in Progressive Collapse with Fiber Model [PDF]
Advances in Computer Science Research, 2015 An advanced finite element model (FEM) is presented with fiber beam-column element of OpenSees in this study. Using this FEM, non-linear static push-down analysis of a steel frame structure was carried out by the alternate load path method, with two different cases that two different columns are removed respectively.

Development of an index for quantification of structural dynamic response in a railway catenary section [PDF]
, 2020 In an attempt to quantify the amount of the dynamic reaction in a railway catenary system due to the dynamic action created by the interaction with the pantograph of the train, a catenary dynamic index (CDI) is developed.

MECHANICAL BEHAVIOR AND CATENARY ACTION OF RESTRAINED STEEL BEAM UNDER FIRE [PDF]
, 2021 To investigate the mechanical behavior and catenary action of restrained steel beam under fire, experiments were performed on five H-section restrained steel beams exposed to ISO-834 standard fire. At first, mechanical property tensile tests were performed on 3 room-temperature specimens and 8 high-temperature specimens, and variation laws of the ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures
High Voltage, EarlyView.ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.
