Catenary Action during Collapse of Steel MRF Buildings
Structures Congress 2006, 2006Detailed 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.

Simplified theoretical model for prediction of catenary action incorporating strength degradation in axially restrained beams [PDF]
Engineering Structures, 2019 Catenary action is one of the structural mechanisms that could develop in a laterally restrained beam when subjected to large deformation, and it is a primary mechanism in the resistance to progressive collapse of frame structures in the typical scenario

Finite element analysis assessing partial catenary action in steel beams
Journal of Constructional Steel Research, 2015Abstract 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, 2012Traditional 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

Impact of Buckling Restrained Braces on Catenary Action in Steel Framed Structures
2014Buckling 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.

Considering Catenary Action in Designing End-Restrained Steel Beams in Fire
Advances in Structural Engineering, 2005When 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.

Catenary action of restrained steel beam against progressive collapse of steel frameworks
Journal of Central South University, 2012The 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.

Effect of Reinforcement Detailing on Catenary Action in 2-D RC Frame
2017The survivability of a structure under progressive collapse highly relies on its toughness (energy absorption prior to failure). In a 2-D Reinforced Concrete (RC) frame for example, if catenary action is developed, the provision of greater rotational capacity at the support interface would contribute to larger deformations (improving toughness) and ...

Evaluation of progressive collapse potential of steel moment frames considering catenary action
The Structural Design of Tall and Special Buildings, 2008AbstractThis study investigated the effect of catenary action on the progressive collapse potential of steel moment framed structures. Non‐linear static and dynamic analyses of three‐ and six‐story model structures with and without bracing were carried out following the alternate path method recommended by the General Services Administration 2003 ...

Effect of partial debonding on catenary action of reinforced concrete frames
2013Progressive collapse resistance of buildings can be evaluated by introducing a middle column removal scenario to mobilize alternate load paths (ALP). Catenary action, one of ALPs, uses tensile force in beams to balance external loads applied onto structures.
