I'm trying to make a comparison between the maximum allowable uniform load of a beam made of steel vs LVL.

Here is a table of allowable uniform loads for steel W beams:

Here is a table of allowable uniform loads for LVL beams:

https://www.westfraser.com/sites/default/files/products/LVL/LVL%20Users%20Guide%20-%20US%20%20v0415.pdf

In the case of W beams, there is just 1 number for allowable load based on the span. In the case of LVLs, there is 'LL (L/360)', 'TL(L/240)', and 'BEARING.'

"To size a beam for use in a floor, it is necessary to check both live load and total load. Make sure the selected beam will work in both rows. When no live load is shown, total load will control. Spans shown are measured center-to-center of bearing."

Based on this, my understanding is that the TL(L/240) values are most comparable to the allowable load limits for the W beams.

In other words, if I'm reading this right:

Please correct me if I am misunderstanding that :) Also, can anyone tell me what the "BEARING" value of 1.6/4.1 means in this case?

**A W10 x 30 beam with a 14 foot span has a maximum allowable load of 37,000 lbs, while a 1 3/4" x 11 1/4" 2.0E LVL with a 14 foot span would have a maximum Total load (L/240) of 309 lbs/LF * 14 ft = 4,326 lbs.**Please correct me if I am misunderstanding that :) Also, can anyone tell me what the "BEARING" value of 1.6/4.1 means in this case?
