In order to repair the damage, the first step is to support and minimally raise the truss to relieve the presently overstressed members and connections. My intent is to design a structural steel frame to pick up the truss at the structurally appropriate locations, and use bottle jacks supported from shoring platforms to gently raise the frame. I am comfortable with the design of the shoring platforms; however, I would like to know of any references that might be helpful in detailing the support assembly consisting of the bottle jacks and steel frame. My primary concern is stability at the bearings of the steel frame on the jacks.
Thanks in advance for your assistance,
