# section modulus z

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. Any relationship between these

The plastic section modulus, Z x, is used to determine the limit-state of steel beams, defined as the point when the entire cross section has yielded. This property is unique to steel, since neither of the other materials we are considering (wood and reinforced

The plastic neutral axis (PNA) is the line through the cross-section of the beam that separates the area under compression from that under tension. This line is parallel to the direction of the applied stress. One way to define the plastic modulus (Z) is as the first

Section modulus is a geometric (that is, shape-related) property of a beam used in structural engineering. Denoted Z, it is a direct measure of the strength of the beam. This kind of section modulus is one of two in engineering, and is specifically called the elastic section modulus.

Plastic section modulus The plastic section modulus is similar to the elastic one, but defined with the assumption of full plastic yielding of the cross section due to flexural bending. In that case the whole section is divided in two parts, one in tension and one in

There are two types of section moduli, the elastic section modulus (S) and the plastic section modulus (Z). Notation North American and British/Australian convention reverse the usage of S & Z. Elastic modulus is S in North America, but Z in Britain/Australia, and vice versa for the plastic modulus.
