Research on the Judgement Method for Catenary Action of Restrained Steel Beams in Fire
International Journal of Steel Structures, 2020Based 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, 2015Abstract 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.

Analytical investigation on catenary action in axially-restrained reinforced concrete beams
Engineering Structures, 2019Abstract 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.
