### (Section Modulus - TotalConstructionHelp)

The section modulus of the cross-sectional shape is of significant importance in designing beams. It is a direct measure of the strength of the beam. A beam that has a larger section modulus than another will be stronger and capable of supporting greater loads. It includes the idea that most of the work in bending is being done by the extreme fibres of the beam, ie the top and bottom fibres of the section.

### Chapter 2. Design of Beams Flexure and Shear

Select the lightest section from the AISC Manual design tables. From page of the AISC manual, select W16 x 26 made from 50 ksi steel with bMp = 166.0 kip-ft. Step III. Add self-weight of designed section and check design wsw = 26 lbs/ft Therefore, wD = 476 lbs/ft = Design of Beams (Flexural Members) (Part 5 of AISC/LRFD)on the cross-section a A Z = 2 = plastic section modulus of the cross section Shear Shear stresses are usually not a controlling factor in the design of beams, except for the following cases:1) The beam is very short. 2) There are holes in the web of the beam. 3) The beam is subjected to a very heavy concentrated load near one of the supports. I/H section (double-tee) calcresourceMay 12, 2021 · A_c=A_t. , the plastic modulus, of an I-section, around x axis, is calculated like this:Z_x = A_c Y_c + A_t Y_t \Rightarrow. Z_x = 2 A_c Y_c \Rightarrow. Z_x = 2 {A\over2} {1\over A} \left ( {b h^2 \over 4} - { (b-t_w) h_w^2 \over 4}\right) \Rightarrow. Z_x = \frac {bh^2} {4} - { (b-t_w) h_w^2 \over 4}

Section Modulus - an overview ScienceDirect TopicsFor a simply supported beam with a uniform distributed load over its full length, the maximum bending moment is wL2 /8 and thus the maximum bending moment for this beam is 10 × 4 2 /8 = 20 kNm. Hence, the required section modulus is:Z = M max = 20 × 10 3 8 × 10 6 = 2 5 × 10 3 m 3.
