What Is Section Modulus

It is a direct measure of the strength of the beam.

What is section modulus. The section modulus is used to to find the minimum required beam that will support the bending load by looking in tables provided such as in the manual of steel construction. Hull girder section modulus is a well accepted parameter measuring the longitudinal bending strength of ships. Any relationship between these properties is highly dependent on the shape in question.

Hull girder section modulus to the deck often determines the bending strength of the entire hull girder. The ratio of the maximum moment on a beam and the maximum fiber stress or moment of inertia over distance to nuetral axis of the member. Other geometric properties used in design include area for tension radius of gyration for compression and moment of inertia for stiffness.

Higher the section modulus of a structure the more the resistive it becomes to bending. It is indicated by s. 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. Also it is the measure of strength of given member. It has nothing to do with timber stainless steel aluminum plastic or your standard structural steel.

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. Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. It is termed as the ratio of second moment of area and distance from n a neutral axis to the extreme fiber.

The stress in the outermost section of beam is computed with the help of section modulus. The section modulus is a number. This modulus is perhaps the single most important design parameter describing hull girder strength.
