Section Modulus Table
There are two types of section moduli the elastic.
Section modulus table. Equations for the section moduli of common shapes are given below. Western species section properties. Following table is providing properties for the following.
These tables provide cross sectional area section modulus and moment of inertia for both x x and y y axis for standard glulam sizes. Douglas fir larch. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members.
Any relationship between these properties is highly dependent on the shape in question. It is often reported using y c where c is the distance from the neutral axis to the most extreme fiber as seen in the table below. Other geometric properties used in design include area for tension and shear radius of gyration for compression and moment of inertia and polar moment of inertia for stiffness.
