Maximum values of angular distortion associated with plastic yielding and collapse of straight concrete sections

Description

The capacity of a reinforced concrete structure to assume an angular distortion depends among other factors on the stiffness and ductility of each section. Therefore, global values such as those established by the CTE‐DB‐C (2006) for the E.L.S. may be conservative or risky depending on the geometric characteristics of the section, their assembly, or material strength. The aim of this Communication is to establish a range of maximum values of angular distortion associated with the initial plastic yielding of the material and collapse or straight concrete section. To do this we use the modification of the classic diagram pivots and compatibility equations, as well as the method of nonlinear iterative calculation in order to obtain a balance between efforts and curvature of the section.
