The role of I-beams

1. I-beams are the main load-bearing members of steel structures. Due to the relatively wide flange of I-beams, the beam height and span can be greatly reduced, making it easier to manufacture larger spans with smaller materials

2. At the same height, the smaller the ratio of cross bar (or longitudinal) to web thickness, the greater the height of the bending section.

3. For the same bearing capacity, the thicker the web, the better the stiffness

4. When subjected to dynamic loads, small cross bar spacing and narrow flange can reduce the moment of inertia;

5. For structures of the same height, the actual working pressure of I-shaped steel structures with large web thickness is greater than that of thin-walled steel structures;

6. When the structure requires certain overall stability requirements (such as high-rise buildings), it is preferable to choose the I-shaped section form with a narrow web width;
