The following functions are used for calculating the section properties of various shapes defined by using T=”Section” objects. By utilizing these functions, you can seamlessly extract essential properties that aid in design, analysis, and engineering tasks. Explore the following functions to empower your workflow and gain valuable insights into the structural behavior of diverse shapes. The naming convention is informative and helps users understand the purpose of each function.

Here are the functions;

sectionAx( Section ) → number

This function requires a T=”Section” object as input and calculates the section area. If the section is a composite section, the function automatically converts determines the modulus and calculates the equivalent area.

sectionAg( Section ) : → number

This function requires a T=”Section” object as input and calculates the gross area of the section without converting section modulus if the section is composite.
