I、Urgent request: 7m span, total weight 12 tons, height 6 meters, width 1.5, what kind of I-beam should be used? Thank you, urgently needed
I calculated a simply supported beam consisting of two main beams with a span of 7m, a total weight of 12 tons, a height of 6 meters and a width of 1.5m. After a rough calculation of the uniformly distributed load, 28b I-beam is better. If it is a crane with concentrated load, it is better to use No. 36b I-beam. The materials are all Q235B (material selection depends on the working environment). Because your parameters are not clear, this is just a rough calculation. If you study your design carefully, the steel section should be able to be made smaller.
The span is 7.5 meters, the total length is 15 meters, and the total weight is 25 tons. It is recommended that you do not use the purchased I-beams. You can choose to weld the beams yourself, which can save a lot of materials, or use the senior brother upstairs. It is also a good choice to use angle steel and channel steel seat trusses, so that you will not be scolded by the boss. I originally had calculation pictures for you to look at, but I won’t upload them. I’ll give them to you next time I get a chance.
