Abstract

A 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 diaphragms are properly tied together to form a structural unit. When diaphragms and shear walls are used in the lateral design of a building, the structural system is termed a "box system".
