Summary
The uniaxial bending analysis of trapezoidal cross sections and the bending
analysis of rectangular cross sections are both based on the assumption of
Bernoulli's-hypothesis (all adjacent plane cross sections remain plane during
loading). However, the analysis procedures for trapezoidal cross sections deviate
from the analysis of a rectangular cross section due to a linear change in the width of
the cross section.
The paper presents a detailed analysis of a trapezoidal cross section
implementing the bilinear design stress-strain relationship for the concrete. The
paper covers both possibilities that result from the value of the maximal strain in
concrete
For both cases mentioned, the paper presents the development of the analytical
expressions for coefficients
