The phrase "a critical section" is correct and usable in written English.
It is typically used in computer science and programming to refer to a part of a program that accesses shared resources and must not be executed by more than one thread at a time.
Example: "To prevent data corruption, we need to ensure that only one thread can enter the critical section at any given time."
Alternatives: "a crucial segment" or "a vital section".

In the developed model, a shear critical section has been idealized with a single web element for shear and the top and bottom chords for flexure, respectively.
In the analysis algorithm, the longitudinal strain ( varepsilon_{x} ) at mid-depth in a shear critical section is initially given.
With consideration of the top and bottom chords, simple flexural analysis was employed, which gave longitudinal strain at the mid depth in a shear critical section.
The method is based on a quadratic nonlinear failure criterion, using normalized driving forces, their simplified actions, and an approximate critical section location and angle.
