A simplified analysis of catenary action in steel beams in fire and implications on fire resistant design

Steel and Composite Structures, 2006
This paper describes the results of a numerical investigation of the large deflection behaviour of steel beams under fire conditions, taking into consideration the effect of catenary action provided by the surrounding structures. The main focus is on the development, validation and application of a simplified calculation method that may be adopted in ...

Finite element modelling of reinforced concrete framed structures including catenary action

Computers and Structures, 2010
In this paper, a 1D discrete element is formulated for analysis of reinforced concrete frames with catenary action. A force-based formulation is developed based on the total secant stiffness approach and an associated direct iterative solution scheme is derived.

Catenary action in steel-framed buildings

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2007
The current paper is of relevance to engineers engaged in the design of buildings in which severe column damage resulting from malicious actions is a design scenario. The tying force method as used for providing robustness to steel-framed buildings relies upon catenary action to redistribute loads following column damage.

Research on the Judgement Method for Catenary Action of Restrained Steel Beams in Fire

International Journal of Steel Structures, 2020
Based on fire tests, a parametric numerical simulation on the catenary action of restrained steel beams in fire was performed by the finite element software ABAQUS. It can be known that axial constraint stiffness, rotational constraint stiffness and load ratio are key factors that affect the catenary action in fire.

Catenary action in steel framed buildings with buckling restrained braces

Journal of Constructional Steel Research, 2015
Abstract Progressive collapse is disproportionate failure of the structure due to the failure of a relatively small part of it. Catenary action is a load mechanism that is developed to resist the additional loads as a result of sudden column loss and prevent disproportionate collapse.

Numerical analyses of steel beam–column joints subjected to catenary action

Journal of Constructional Steel Research, 2012
Abstract This paper presents the numerical results of 6 beam–column joint tests using six types of connections: web cleat, fin plate, top and seat with web angles (TSWA) (8 mm thick angle), flush end plate, extended end plate, and TSWA (12 mm thick angle). Both static and explicit dynamic solvers were employed to overcome the problems of convergence,

Analytical investigation on catenary action in axially-restrained reinforced concrete beams

Engineering Structures, 2019
Abstract Catenary action featuring axial tension forces plays a critical role in resisting the applied load when reinforced concrete beams with adequate axial restraints experience large deformations. It can be used as the last line of defence under some extreme scenarios.

Effect of floor joint design on catenary actions of precast floor slab system

Engineering Structures, 2017
Abstract To prevent progressive collapse of building structures, the establishment of the catenary action mechanism of beams or slabs is crucial so that adequate post-collapse resistance can be attained. It is believed that the joint design of precast floor system, e.g. the tie design, plays a key role in facilitating such a mechanism.

Effect of Catenary Action on Dynamic Increase Factor in Progressive Collapse Analysis

, 2019
Il collasso progressivo è una modalità di collasso che ha inizio con il danneggiamento prodotto in pochi elementi strutturali da condizioni di carico anomale. Il collasso di tali elementi strutturali in presenza di eventi eccezionali è un fenomeno non lineare e dinamico che mobilita diversi mec-canismi resistenti.
