WebA drag truss acting as diaphragm support and boundary chord requires boundary nailing stipulation. Drag trusses interior to a diaphragm will generally receive unit shears from two separate diaphragm spans. Both sequencing and pattern of the nailing must be evaluated. The staggered nature of the sheathing generally dictates the sequencing.

"WebThe use of a consistent truss model is an essential require-ment when evaluating code provisions. The critical nodal stresses are entirely dependent on the configuration of the model and geometry of the nodal regions. In this study, a single-panel STM was used to analyze deep-beam test results (Fig. 4). Nonhydrostatic nodes were proportioned " - Diaphragm truss method

Diaphragm truss method

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.
