Which bearing capacity is stronger?
Under the same thickness, the bearing capacity of I-beam will be better than that of channel steel, and the price of channel steel will be lower than that of i-beam.
On both sides of I-beam symmetrical shape, the stress is not eccentric, and channel forming easy, cheap, and their "strong bearing capacity, which is closely related with their size and shape, a special mechanical bending section coefficient We - shape coefficient in mechanics of materials, according to the size of the check material the manual, the who, who is that the" strong bearing capacity ", because the maximum stress of B beam and the bending moment is proportional to M, and the cross-section coefficient is inversely proportional to We.
Both I-beam and channel steel should be used as beam members, and the bending moment can be greater than that of other kinds of materials under two weight conditions. Because when it is used as a beam, the stress produced by the bending moment is X type, the stress at the top and the lower part of the beam is maximum, and the middle part is smaller, while the I-beam and the channel steel are both the top and the bottom.
