Which performs better in terms of load bearing, H-shaped steel or I-shaped steel? How to analyze it? Are there any relevant references?
It must be I-beams; the prices vary, and the standards applied are different as well. H-beams are generally used in welding for ordinary steel structures.
See http://bbs.hcbbs.com/viewthread.php?tid=319161
I have studied the content related to the 3rd floor and find it good; I-beams are generally produced by hot rolling, and there are heavy-duty and light-duty types； H-shaped steel is generally fabricated by welding steel plates; I believe that I-beams should be the first choice in design, with H-shaped steel being used only when necessary.
It’s definitely because I-beams have better load-bearing capacity; I-beams are generally produced by hot rolling, while H-beams are usually fabricated by welding steel plates together.
What was said upstairs is incorrect; H-shaped steel was developed relatively late, so it isn’t well-known to many people. In fact, H-shaped steel can also be produced through hot rolling, and there are corresponding **standards** for it. Whether to use I-beams or H-shaped steel depends on the requirements, as H-shaped steel has better mechanical properties.
I agree with the opinion above; H-shaped steel was originally produced through welding (as specified in YB3301-1992), but it has now evolved into a **standard product manufactured by hot rolling, with the standard number being GB/T11263-1998. The specific stress conditions are related to the specifications of the steel sections and the direction of the applied forces; under the same conditions, H-shaped steel can withstand stresses better.
Refer to the H-beam **standard GB/T11263-98.
It cannot be generally said which one, H-shaped steel or I-shaped steel, has better load-bearing capacity; the appropriate choice should be made based on specific dimensions and application scenarios. If one type of profile is better than another in every situation, then the inferior profile has no reason to exist. Then no one will choose it.
There are differences of opinion regarding the forces at play; do they each have advantages depending on the direction of the forces acting on them? Could that expert conduct a detailed force analysis? Thank you!
I feel like nobody has read through the content of that link. Nowadays, most H-shaped steel is produced by hot rolling, and in terms of load-bearing capacity, it’s clear that H-shaped steel is superior to I-beams; it is an economical cross-sectional profile with excellent mechanical properties. Compared to traditional hot-rolled I-beams, its stiffness in the weak axis can be increased by more than twice. It is **’s encouragement to use profiles. For specific details, please refer to my reply in the above topic; I will not repeat it here. Additionally, I hope the moderator can provide appropriate comments based on the replies, to avoid misleading everyone. Thank you so much, moderator!
