Good Afternoon,
I am looking for input on the plan I have for reworking the framing of an old shed on my property.
The shed has a gambrel roof and I am looking to increase the overhead space to make use of that room, but the current support structure is limiting that. Part of the issue is that the ridge beam and “purlins/secondary ridge beams” are not solid 24′ beams but rather are 12′ beams with a 4′ beam and an 8′ beam on either end of each beam.
The plan I have is to place doubled 2×10 crossmembers (yellow in the picture) below the joint on each secondary ridge beam to span the width between the secondary beam. The ridge beam would then be supported by this crossbeam, and the cross beam would be supported by doubled up 2x4s (blue) that would be secured to the foundation.
I have attached some pictures showing what I am thinking. What am I missing? What am I not considering?
Thanks,

How about a 24 ft beam under each existing beam?
Might not have the support strength at each end of the 24' beam that you suggest.
This really requires input from a structural engineer having complete knowledge of the existing structure. Gambrel roofs can be tricky to modify.
Might be helpful to know where this structure is located
I considered replacing the ridge beams but was hoping that there were other alternatives that would allow me to make use of the overhead space without ripping apart the roof.
I'm located in North Idaho BTW so I do need to consider that we get snow.
I don't have a quick & easy solution without understanding the entire structure.
