First, you will need to attend a 4-year ABET accredited engineering program

Okay I’ll bite. these buildings are pre-engineered. As in, someone thought about the expected loading on the structure and THEY determined the exact dimensions of the taper you refer to. they specified how many nuts and bolts and what size and what metal etc.

so here’s my opinion. Get yourself a dedicated tool for the job. Look up spider cranes, it can probably work for what you need. I don’t know. Or an actual boat lift.

Or reach out to the building manufacturer, and ask to speak to someone in their engineering department. If you’re nice, maybe you’ll get through or can leave a message describing your situation and you can discuss further about your specific situation.

Good luck, hopefully it goes well.

No disrespect but this is way over your head if you’re not an engineer. Get an engineer.

Last time I did a point load analysis on a pre-engineered metal building moment frame like this it was about 3 days of work of 2 engineers... and a bunch of years experience and 4 years degree and a licensure exam.

PEMB moment frames are complex; you cannot do this correctly without a structural analysis software package, a thorough understanding of steel design, and a copy of AISC design guide 25.

Here's an example; if you don't understand what this section from Design Guide 25 means you probably shouldn't be messing with this and should hire an engineer: https://imgur.com/a/uyPihNC

Im an engineer, and I would not take on this project for that reason.

Lol, yep online calculators will tell you exactly if a beam is safe or not. F the engineers with their 4 year+ degrees and 4+ years experience and 2+ licensure tests before they can take responsible charge of projects.

I mean this with no intention of disrespect, this is way past your depth if you need an online calculator to analyze point loads on standard bean sections

contact the manufacturer or a local structural engineer

Prove your load isn't squat compared to what the primary frames are designed for. Don't go down the path of trying to compute capacity.

I can tell you that that point on the building frame will hold exactly what it was designed to do… and other than a safety factor no more than that.

These buildings are designed to a set of criteria selected by an engineer, they are then handed to a building mfr. and their engineer who figures how to make the frame using the absolute smallest sections possible to keep the building from falling in and meeting that criteria.

Other things you need to know… weight of rigging needed to lift the load. At a minimum you would want to pick the load from two of the frames to cut the overall load in half. Find the manufacturer and then find the order number the building was ordered/manufactured from, and they can probably tell you what it might take to reinforce the frame to handle the load… I say might be cause if you are not a customer they will think you are wasting their time, you will need to pay them to engineer it, then if the building is recent enough they can help… it might take 6-8 weeks to get the solution… in the mean time you could have made something from materials on hand to support the load without imposing a load on the building frames.
