What are the load-bearing capacity of rectangular and I-beam steel sections of the same size?
You check the steel form to see a Wx value in it, which represents the most important load condition.There are two general force formulas:F/A: force / areaM/Wx: bending moment / flexural modulusThere are other instability calculations.
Therefore, if the stability is not considered, the bearing capacity of I-beam is large.But the stability of the rectangular steel is better, it is not easy to lose stability.
In the same section size, the web and wing plate of I-beam are higher than rectangular steel, so the modulus of bending section is also high.
