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.

Analytical study on reinforced concrete frames subject to compressive arch action
Engineering Structures, 2017Abstract Reinforced concrete beams can resist applied vertical loads through the development of compressive arch action (CAA) when adequate horizontal restraints are provided at the ends. However, at the frame level, CAA tends to push adjoining columns outwards and may induce premature flexural or shear failure to the columns.

Evaluation of compressive arch action of reinforced concrete beams and development of design method
Engineering Structures, 2019Abstract This paper describes a study on the compressive arch action of reinforced concrete beams with various levels of horizontal restraints. An analytical model is proposed based on Park’s assumption, in which the tension-stiffening effect of steel reinforcement and its slip relative to beam-column joints are considered. The model is calibrated by

Abstract To investigate the compressive arch action (CAA) of prestressed concrete beam-column assemblies, bonded prestressed concrete (BPC) assembly models were established and validated using previous experimental data. The beneficial effect of CAA on the progressive collapse resistance of BPC structures is quantified by the load increase ...

Abstract Compressive arch action (CAA) is one of the important resistance mechanisms against progressive collapse in reinforced concrete (RC) frame buildings at small deformations. In this study, the distinguishing features of Gene Expression Programming (GEP) are utilized in order to establish a prediction model for the CAA capacity of RC beam ...

Compressive arch action in beams of steel frames subjected to a column loss
ce/papers, 2023AbstractSteel frames subjected to a column removal typically exhibit a complex load resisting mechanism characterised by three contributions: i) beam yielding mechanism, ii) compressive arch, and iii) catenary action. The development of compressive arch actions in the beams bridging over the lost column has not been yet thoroughly investigated in steel
