Equations for the section moduli of common shapes are given below. There are two types of section moduli, the elastic section modulus (S) and the plastic section modulus (Z).

Jan 5, 2025 · How do you calculate the section modulus? The Section modulus S is calculated by dividing the Moment of Inertia I by the distance z from the Cross-section centre to the edge.

Use this tool to calculate the section modulus, second area moment, and neutral axis of many structural profiles, given their dimensions.

The plastic section modulus is calculated as the sum of the areas of the cross section on either side of the PNA, each multiplied by the distance from their respective local centroids to the PNA.

The plastic section modulus is necessary to calculate plastic moment capacity of the section. The plastic section modulus is the sum of moment of area of area under compression about PNA …
