How is the combined cross-sectional area of the web and the stirrup (small end) calculated? How is the bending moment capacity factor of the combined section of the web and stirrups (at the smaller end) calculated? Which expert can offer some guidance?
Calculate the combined cross-sectional area of the web and stirrup (small end) by yourself. For the bending moment capacity factor of the combined section of the web and stiffener (small end), please refer to the relevant sections in the Mechanical Design Handbook.
1. The number of reinforcement plates: there is a certain number in each row. 2. Calculate the center of the cross-section of the reinforcement plates; for each row of cross-sections in the web, the calculation must be performed once. 3. Calculate the height of the section’s centroid. 4. Calculate the moment of inertia for each section. 5. Calculate the total moment of inertia. 6. Determine the flexural section modulus by dividing the total moment of inertia by the height of the centroid. 7. Calculate the combined cross-sectional area of the web and the stiffeners.
In AutoCAD, draw the cross-section and turn it into a region; then move the centroid of the cross-section to the 0 point, and you can proceed with the query.
The question that arises right away is: what exactly are you calculating, and which standards apply?
In mechanics of materials, there is something called parallel displacement, and there’s a formula related to it. You’ll know once you see it
