precast strongback
 

precast strongback
its been a while, but i need to design a strongback for a couple precast walls. i am taking my moment in the strongback and dividing by the depth of the strongback, to get my shear along the wall...that make sense, or is there something i am missing?
you're really missing it! if the strongback is doing all the work, you simply have a connection that is strong enough to transfer the weight of the precast to the strongback, intermitently along it's length.
