WebA diaphragm is a flat structural unit acting like a deep, thin beam. The term “diaphragm” is usually applied to roofs and floors. A shear wall, however, is a vertical, cantilevered diaphragm. A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit. (See ... http://www.nehrp.gov/library/techbriefs.htm WebWhen the load under consideration is seismic, the diaphragms themselves often constitute a majority of the inertial mass, as well as the means of delivering inertial forces to the vertical elements of the seismic load resisting system (SLRS). fll baggage claim map
