Calculate plastic section modulus. If your beam has any unusual geometry such as flanges in an i beam though measure those dimensions as well. With the width and height of each rectangle entered as input data in cells c9 d9 cio d10 cll and dll the value of the plastic modulus is calculated by the spreadsheet. I hope this helps.

The cross section is divided into 3 rectangles as shown in figure 4b. The plastic section modulus is then the sum of the areas of the cross section on each side of the pna which may or may not be equal multiplied by the distance from the local centroids of the two areas to the pna. The most important values for calculating the plastic modulus of a beam are generally the width and height of the beam s cross section.

How to calculate plastic section modulus for i beam. Calculate the plastic modulus of the cross section shown in figure 4a. The plastic section modulus can also be called the first moment of area.

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. The plastic section modulus is the sum of the areas of the cross section on each side of the pna which may or may not be equal multiplied by the distance from the local centroids of the two areas to the pna.
