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.

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 ...

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.

Catenary Action during Collapse of Steel MRF Buildings

Structures Congress 2006, 2006
Detailed finite element simulations are used to investigate the large deformation behavior of seismically designed beam-column subassemblies. The numerical model employs a micromechanical fracture model for steel that is calibrated to existing test results.

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,

Finite element analysis assessing partial catenary action in steel beams

Journal of Constructional Steel Research, 2015
Abstract One potential means for designing steel structures for progressive collapse resistance is to include considerations of catenary action in order to efficiently and economically allow beams to be designed to resist increased levels of load relative to what is currently considered in practice. However, the current inventory of typical girder-to-

Component-based Model of Bolted-Angle Connections Subjected to Catenary Action

Proceedings of the 10th International Conference on Advances in Steel Concrete Composite and Hybrid Structures, 2012
Traditional design of connections is limited to moment-rotation characteristics and the information about the deformation capacities of connection components is quite limited. Thus, it is necessary to develop a new mechanical model, which could predict the deformation capacity of each connection component and the development of catenary action. In this

Considering Catenary Action in Designing End-Restrained Steel Beams in Fire

Advances in Structural Engineering, 2005
When a building compartment is subjected to fire attack, there are complex interactions between the fire affected members with the surrounding members. The behaviour of the steel frame members in fire can be drastically different from that of its member in isolation. This paper studies the behaviour of steel beams with the increase of temperature from

Impact of Buckling Restrained Braces on Catenary Action in Steel Framed Structures

2014
Buckling restrained braces (BRBs) are passive control devices that have superior ductility and energy dissipative behavior compared to other lateral resisting systems. Previous research has shown that BRBs can be utilized to minimize the damage in steel structures resulting from seismic loads.

Catenary action of restrained steel beam against progressive collapse of steel frameworks

Journal of Central South University, 2012
The changing law of internal forces during the whole deformation development process was analyzed. The process was divided into five stages based on the internal force state of the beam and the assumptions of internal force relationship of five stages were proposed.
