2 & 3: Wall to Roof or Floor Anchorage
The URM walls must be tied to the horizontal diaphragms (roof and floors) to increase their capacity for out-of-plane loading and reduce the risk of catastrophic failure. There are many ways to anchor the walls to the diaphragms. Through-bolting with large bearing plates on the exterior, combined with epoxy adhesive in the URM wall wythes will provide tensile and shear resistance for the wall anchor and is one possible solution. One caveat in determining the optimal location for these anchors is usually dependent on the fact that many URM buildings utilize beam pockets to support the joists. The wall anchor will perform better when it is away from the beam pocket. When deciding on the anchor location, the midpoint between framing is more ideal, but requires additional framing elements to attach to the joists.
