Analytical Model for Compressive Arch Action in Horizontally Restrained Beam-Column Subassemblages [PDF]
ACI Structural Journal, 2016 This paper presents an analytical model to predict the compressive arch action (CAA) of reinforced concrete beam-column subassemblages. In the model, a new method is proposed to quantify the strains of longitudinal reinforcement in the beam. Instead of equivalent rectangular concrete stress block, the constitutive model for concrete is employed to ...

Applied Sciences, 2023 The great diffusion of masonry arch bridges, sometimes of historical interest, requires the development of simple but effective methodologies for a preliminary but reliable evaluation of their static and seismic capacity. In this paper, the behaviour under longitudinal seismic actions is analysed by using the mechanism method.

Simplified Compression Arch Action Model for R/C Beam-column Assemblages
Journal of Engineering Research and Reports, 2019 A set of analytical equations are developed for calculating the beam-column assemblage flexure action capacity and compression arching action capacity under a middle column removal scenario. The suggested equations covered most of the main parameters affecting the assemblage behavior including seismic detailing, longitudinal reinforcement ratios ...
