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.

Abstract In case of accidental loading, compressive arch action and catenary action in beams and slabs can be mobilised to resist progressive collapse of reinforced concrete structures. Analytical models have been proposed for reinforced concrete beam-column sub-assemblages under compressive arch action and catenary action.

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.

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 ...

Effect of floor joint design on catenary actions of precast floor slab system
Engineering Structures, 2017Abstract 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.

Chord rotation demand for effective catenary action of RC beams under gravitational loadings
Structural Engineering and Mechanics, 2016Many experimental and analytical studies have been conducted with beam-column subassemblages composed of a two-span beam to investigate the progressive collapse resistance of RC frames. Most study results reveal a strength-decreased transition phase in the nonlinear static load-deflection curve, which may induce dynamic snap-through response and ...

Effect of Catenary Action on Dynamic Increase Factor in Progressive Collapse Analysis
2019Il 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.
