ABSTRACT
Bulging or ballooning in walls can be caused by overloading of floors which transmit these loads under deflection as inclined forces on the walls. Bulging may also be exacerbated by a lack of restraint from the floor structure if the appropriate corrections to parallel joists are missing. The effect in both cases may be a full-height bulging of the wall-the cause of which will require investigation for positive identification. Note that a wall which is bulging may pull the parallel connected floor joists into deflection also.
