Floor-wall diaphragm connection unknown [FWC99]

It is not known if there are any connections between the floor diaphragm(s) and the walls that are capable of transfering in-plane forces from floors to wall and restraining outward displacements of walls. There is insufficient information available or the connections are not visible from a survey.

It is not clear if floor-wall diaphragm connections are present for this unreinforced brick masonry building (S. Brzev)
