Methods of analysis of a reinforced concrete section under bending with axial force in the post-yield range

open access: yesBudownictwo i Architektura, 2014
Predicting the behaviour of plastic hinges subjected to large inelastic deformations caused by extreme loads such as earthquakes plays an important role in assessing maximum stable deformation capacities of framed concrete structures. This paper presents
