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

Catenary action in strip-reinforced wood and timber beams
Construction 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 ...

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

Testing and modeling dowel and catenary action in rebars crossing shear joints in RC [PDF]
Engineering Structures, 2017 Abstract This paper presents a detailed study of the shear behavior of two-sided dowel joints, which includes initiation of dowel action at small shear displacements and development of full catenary action in the reinforcement at large displacements. In addition to experimental results, the paper also presents a simple, second order plasticity model ...

Dynamic Behaviour and Catenary Action of Axially-restrained Steel Beam Under Impact Loading [PDF]
Structures, 2017 In this paper, the dynamic behaviour and catenary action of axially restrained steel beam under impact loadings is examined through a combination of experimental and numerical investigations. It describes and discusses the results of six impact tests on the axially restrained welded H-beams by means of the drop hammer test machine. The main behavioural

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