Progressive collapse analysis of reinforced concrete in buildings L-shaped plan [PDF]

open access: yesJournal of Structural and Construction Engineering, 2018
One of the most important issues discussed structural passive defense is progressive collapse. Progressive collapse occurs the sudden destruction caused by the deliberate structural member by accidents or disasters, such as earthquakes and terrorist ...

A review of progressive collapse research and regulations [PDF]

open access: yes, 2014
History has demonstrated that buildings designed to conventional design codes can lack the robustness necessary to withstand localised damage, partial or even complete collapse. This variable performance has led governmental organisations to seek ways of

Active Control of Contact Force for a Pantograph-Catenary System

open access: yesShock and Vibration, 2016
The performance of the high speed trains depends critically on the quality of the contact in the pantograph-catenary interaction. Maintaining a constant contact force needs taking special measures and one of the methods is to utilize active control to ...

A Modified Catenary Model with Application to the Analysis and Design of Retrofit Cables for Progressive Collapse

open access: yesInfrastructures, 2018
Progressive collapse, the extensive or complete collapse of a structure resulting from the failure of one or a small number of structural components, has become a focus of research efforts and design considerations following events occurring at the Ronan

Influence of Embankments with Parapets on the Cross-Wind Turbulence Intensity at the Contact Wire of Railway Overheads [PDF]

open access: yes, 2010
Winds as an environmental factor can cause significant difficulties for the railway system operation. The railway overhead has been particularly vulnerable to cross-winds related problems, such as development of undamped oscillations due to galloping ...

Numerical Simulation of Vortex-Induced Vibration of TTR and SCR

open access: yesJournal of Marine Science and Engineering, 2022
Top tensioned risers (TTRs) and steel catenary risers (SCRs) have been widely used in the field of marine engineering. They are commonly used to transport fluids from subsea wells to surface platforms. Under the action of ocean currents, these risers are

Energy efficiency and integration of urban electrical transport systems: EVS and metro-trains of two real European lines [PDF]

open access: yes, 2019
Transport is a main source of pollutants in cities, where air quality is a major concern. New transport technologies, such as electric vehicles, and public transport modalities, such as urban railways, have arisen as solutions to this important problem ...

Experimental and Theoretical Investigations on Progressive Collapse Resistance of the Concrete-Filled Square Steel Tubular Column and Steel Beam Frame under the Middle Column Failure Scenario

open access: yesShock and Vibration, 2019
A static loading test was carried out on a 1/3-scale concrete-filled square steel tubular column-steel beam frame (CFSTSBF) specimen with 2 spans to study its progressive collapse behaviors under the middle column failure scenario using the alternate ...

The Progressive Collapse Resistance Mechanism of Conventional Island Shield Buildings in Nuclear Power Plants

open access: yesBuildings, 2023
In China, conventional island shield buildings (CISBs), which are situated close to the nuclear islands of nuclear power plants, are class III seismic items. This is the most important level in the seismic fortification standard.
