The Truss Industry (WTCA and TPI) places the following general limits on shear load transfer through the truss. Trusses are permitted to transfer load in the F1 direction from the roof sheathing to the wall below, per the BCSI — B8 Summary Sheet, provided the:
Trusses that do not meet all the conditions above must resolve the lateral load transfer between the diaphragm and the wall by using blocking or some other means.
