Section Modulus Calculation

Section modulus is a geometric property for a given cross section used in the design of beams or flexural members.

Section modulus calculation. To calculate the section modulus the following formula applies. Where i moment of inertia y distance from centroid to top or bottom edge of the rectangle. Optimal beam free section properties calculator registered users.

Free tool to calculate section properties such as area centroid moment of inertia section modulus and radius of gyration. The links below on the left are section modulus calculators that will calculate the section area moment of inertia properties of common shapes used for fabricating metal into various shapes such as squares rounds half rounds triangles rectangles trapezoids hexagons octagons and more. Z max and z min.

Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. Equations for the section moduli of common shapes are given below. 4768 beams solved.

For asymmetrical sections two values are found. Z x b h 2 h 4 b h 2 h 4 bh 2 4. Calculating the section modulus.

The plastic section modulus for a rectangular cross section can be determined by multiplying each section half e g the shaded area shown in figure 1 50 by the distance from its centroid to the centroid for the whole section. Any relationship between these properties is highly dependent on the shape in question. 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.

For symmetrical sections the value of z is the same above or below the centroid.
