The Cross Section Builder can be used to build up a custom cross section and calculate the associated section properties. See the reference section for details on the methodology and the equations used.

### Inputs

Specify each individual shape within the overall (composite) section:

Display Units:

### Calculated Properties

#### General Properties

 A = area xc = centroid location in x-direction yc = centroid location in y-direction W = overall width of section H = overall height of section

 cx = centroidal distance about x-axis Icx = centroidal moment of inertia Sx = section modulus rx = radius of gyration

 cy = centroidal distance about y-axis Icy = centroidal moment of inertia Sy = section modulus ry = radius of gyration

You may add this section to your cross section database. Note that the x-axis of this cross section will be considered the primary bending axis.
