Section Modulus I Beam

Other geometric properties used in design include area for tension radius of gyration for compression and moment of inertia for stiffness.

Section modulus i beam. Strength of materials beam deflection and stress. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. A beam that has a larger section modulus than another will be stronger and capable of supporting greater loads.

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 concrete has the necessary ductility to reach this state. Therefore strength of any section will be dependent over the section modulus and we can say that if a beam has higher value for section modulus then beam will have more capacity to bear the bending moment for a given value of bending stress or beam will be stronger and hence section modulus of the beam will indicate the strength of the section. Any relationship between these properties is highly dependent on the shape in question.

It is a direct measure of the strength of the beam. The section modulus of the cross sectional shape is of significant importance in designing beams. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members.

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.
