Connecting new steel roof trusses to the old stone building

[Eng.Oarkeed]

Hi!

What are your recommendations for connecting a new steel roofing system to an old concrete historical building? and can you provide a reference to design the connection?

One that only impose vertical loads would seem like a good idea, but you're going to need to provide more information than "an old concrete building"
