How much weight can I hold for No. 30 I-beam?
The No. 30 I-beam is a four span continuous beam, span 3 meters, only bending capacity, 10 tons of midspan load is more than enough.So, I think it's not very meaningful for the project to only calculate the beam carefully! Design the whole structure carefully.
This is a steel structure, safe bearing capacity of steel structure, it is important to combine different components, structure and computing node is very important, not only to see the I-beam girders, columns, joints and foundation are very important. Take the landlord used 108 * 4 steel, the section is estimated to be less than 1257mm -, 215N/mm - axial compressive strength design value, the stability coefficient estimates of less than 0.5, and the eccentricity is not considered, a preliminary estimate of each pipe under the load calculated only ten tons, and then divided by partition coefficient of load!
This is calculated, in fact, the actual load-bearing area should be in the distance between the iron pipe, 12/5, 3 meters apart According to the interval of 4 meters, 30# I-beam is divided into 32A and 32C two, bearing respectively 9.7T and 10.6T, that is, each two supporting iron pipe can load 9.7 tons.
