Effects of Corrosion on Compressive Arch Action and Catenary Action of RC Frames to Resist Progressive Collapse Based on Numerical Analysis. [PDF]

open access: yesMaterials (Basel), 2021
Many negative factors can influence the progressive collapse resistance of reinforced concrete (RC) frame structures. One of the most important factors is the corrosion of rebar within the structure. With increasing severity of corrosion, the duration, robustness, and mechanical performance can be greatly impaired.

Strain and crack development in continuous reinforced concrete slabs subjected to catenary action [PDF]

open access: yesStructural Engineering and Mechanics, 2015
Several structural calamities in the second half of the 20th century have shown that adequate collapse-resistance cannot be achieved by designing the individual elements of a structure without taking their interconnectivity into consideration. It has long been acknowledged that membrane behaviour of reinforced concrete structures can significantly ...

Resistance of Reinforced Concrete Frames to Progressive Collapse at Catenary Action of Beams

open access: yesЖелезобетонные конструкции
The specific properties of deformation and failure of a reinforced concrete frame are investigated under sequential realization of arch and catenary action of beams after removal of the middle row column.

Analysis of galloping response in ice-coated transmission conductors under wind loads. [PDF]

open access: yesPLoS ONE
Conductor galloping is a low-frequency, large-amplitude vibration phenomenon induced by the combined action of ice accretion and wind loads, which poses severe threats to power grid safety. For 500 kV transmission lines in Xinjiang, a strain-displacement

Catenary action in strip-reinforced wood and timber beams

open access: yesConstruction and Building Materials, 2023
At present, the popularity of timber as a structural material is booming. However, the current knowledge on disproportionate collapse prevention and extreme loading of timber buildings is scarce. To prevent disproportionate and progressive collapse, catenary action is an important mechanism, where the axial capacity of bending members is activated ...

Simulation Study on Surface Temperature Distribution of Collector Strip Material Under Pantograph-Catenary Arc of Urban Rail

open access: yesIEEE Access, 2023
With the increasing speed of urban rail trains, the vibration between the pantograph collector strip and the contact wire intensifies, and the pantograph-catenary arc occurs frequently, which severely wear the surface materials of the pantograph-catenary.

Numerical Investigations of Progressive Collapse Behaviour of Multi-Storey Reinforced Concrete Frames

open access: yesBuildings, 2023
This paper presents numerical simulations of multi-storey reinforced concrete frames under progressive collapse scenarios. Reinforced concrete frames with different storeys are modelled using DIANA.

Vulnerability Analysis of Catenary-Bridge-Track System

open access: yesShock and Vibration, 2023
Continuous welded rails on bridges are extensively employed in high-speed railways, where trains are predominantly electrically powered, and the open-air catenary represents the weakest link in the system.

Numerical investigation of the behaviour of bolted and welded top and seat angle connection in progressive collapse of steel structures [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
After failure of a column in structure by an abnormal loading, undesirable performance and damage of connections of the beams connected to the top of this column, can lead to the local failure of floor and in turn result in progressive collapse in the ...

Progressive Collapse Resistance of RC Beam–Slab Substructures Made with Rubberized Concrete

open access: yesBuildings, 2022
Abnormal loads can produce localized damage that can eventually cause progressive collapse of the whole reinforced concrete (RC) structure. This might have devastating financial repercussions and cause numerous severe casualties.
