An Overview of Progressive Collapse Behavior of Steel Beam-to-Column Connections
Applied Sciences, 2020 Local failure of one or more components due to abnormal loading can induce the progressive collapse of a building structure. In this study, by the aid of available full-scale test results on double-span systems subjected to the middle column loss ...

Development of Long Span Type Overhead Rigid Conductor Line of Catenary System
IEEJ Transactions on Industry Applications, 1998 An overhead rigid conductor line in a tunnel is free from the fear of disconnection because the contact wire is not tensioned, and it is superior in maintenance saving. In order to introduce this in open sections, we have developed “a long-span-type overhead rigid conductor line of catenary system.” This contact line structure consists of a contact ...

Contact Loss Simulator to Analyze the Contact Loss of a Rigid Catenary System [PDF]
Journal of Electrical Engineering and Technology, 2017 In this paper, a contact loss simulator for a rigid catenary system was designed and used to analyze the effect on the power source according to the conditions of the rigid catenary system and pantograph. R-bar applied to a high-speed train among the real rigid catenary system was used in the contact loss simulator for rigid catenary systems.

TWO-NODE CATENARY CABLE ELEMENT WITH RIGID-END EFFECT AND CABLE SHAPE ANALYSIS
International Journal of Structural Stability and Dynamics, 2011 The effect of rigid ends is considered in the formulation of a general two-node cable element for the analysis of cable-supported structures. The stiffness matrix of the catenary cable element was derived as the inverse of the flexibility matrix, with allowances for self-weight and pretension effects.

Development of Virtual Tools for the Validation Study of Rigid Catenary Installations
, 2023 AbstractElectrification systems in the railway field have evolved over time, adapting to the new needs that have arisen as technology advanced. The applicable standards seem to leave the systems in which the overhead contact rail is implemented so far in the background, resulting in references to it that are clearly insufficient, even in the most ...

Characterization of the Dynamic Behavior of Transition Systems between Rigid and Flexible Catenary
2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019 The study presented will deal with the dynamic behavior that exists before the transition that occurs at the entrance and exit of a tunnel when a rigid catenary has been installed in the latter while flexible catenary systems are maintained abroad. The transition beam used is an element that aims to mitigate the dynamic differences in the strength of ...
