Well here's my question: I have a single story cinder block

Customer Question

well here's my question: I have a single story cinder block building with a wood joisted tar and gravel roof 85 x 33. there are 2 w18x50 I-beams spanning the width (33ft). 1) 15 ft from the front of the building 2) 15ft from the there with a cinderblock 15 ft from the second beam there is another I-beam between there and the rear wall. The building was built in 1965 to add another 2 stories.
JA: OK. Is there anything else the Structural Engineer should be aware of?
Customer: oops the question was what is the load limit for the 2 I-beams in the front section? Will they support a load limit of 5,000 pounds hanging between them 8 feet from the cinderblock side wall?
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Structural Engineer about your situation and connect you two.

Are you asking about this in addition to the typical dead load and snow load?

I apologize for the delay. I didn't receive a notice that you responded.So are these beans spaced at 15' on center?
What is the city and state so I can look at snow loading?
Do you know the thickness of the gravel? If not, I can make an assumption.

crazy busy week! first beam (center) 13.5' from front of building, 2nd beam 16' center, 3rd beam 18' to concrete beam with 6' span on a supporting cinder block wall spanning the width of the building, this was the original rear wall of the building prior to the loading bay being walled & roofed in, a 4th smaller beam (12" I beam) situated 16' from wall and 3' from the rear wall of the building. The building is located at***** Vancouver, British Columbia, Canada. There is very minimal gravel, we are going to re-roof the building in the near future using vinyl. Our new HVAC unit will weigh >800lbs, no sky lights. You can see in google earth the how the original wall is situated. I have an opportunity to place an 1.5" steel colum to assist in supporting the C8 beam in its center.

No problem. I will get back to you this evening with the results.

The W18x50 will work for the existing load + a 5,000 pound load 8' from the ends provided the top flange is continuously braced and the steel is Gr. 50. This is good for L/240 deflection.
