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

Abstract This paper presents the analytical models to predict the reverse arch action (RAA) and the compressive arch action (CAA) of unbonded prestressed reinforced concrete (UPRC) beam-column sub-assemblages under column removal scenarios. In the models, the realistic stress–strain model for concrete is applied to calculate the compression force ...

Semi-analytical model for compressive arch action capacity of RC frame structures
Structures, 2020Abstract Compressive arch action (CAA) is one of the favorable resistance mechanisms at low deflections against progressive collapse of reinforced concrete (RC) frame buildings. In this study, Park & Gamble model for calculating the CAA capacity of RC frame structures is modified by incorporating a compressive stress block for high strength concrete (

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 ...

A review of arching and compressive membrane action in concrete bridges
Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2016It is over a century ago that testing of reinforced concrete slabs by the pioneers of the material such as Lord, Turner and Maillart showed that restrained slabs could carry significant loads. Since that time the interest in and knowledge of the internal arching, or compressive membrane action, that enhances the strength of reinforced concrete has ...

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
2020Compressive arch action (CAA) is a favourable structural mechanism to mitigate progressive collapse of reinforced concrete frames. The full development of CAA highly depends on relatively rigid boundary conditions. This paper describes an evaluation of compressive arch action of reinforced concrete beams.

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
