Did you know?
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. These construction systems can be used when designing a building for wind or seismic lateral loads. WebNov 1, 2024 · The alcove creates re-entrant corners in the diaphragm that can tear open and therefore needs collectors. NEHRP and FEMA have documents on this. haynewp (Structural) 2 Nov 17 01:11.

WebDepending upon the increased diaphragm shear demand and building footprint, interior shear walls may need to be engaged. Framing a drag truss over an interior shear wall can help alleviate stress concentrations at diaphragm openings, re-entrant corners, offsets, or reduce the aspect ratio of the diaphragm. WebDiaphragm openings immediately adjacent to the shear walls constitute less than 25 percent of the wall length, and the available length appears sufficient. For conforming buildings, …
WebThe re-entrant corners, where projections of the structure past the re-entrant corner are more than 15 percent of its plan measurement in the given direction is accepted in shapes like L, T, H, C, + shapes. 2. OBJECTIVE OF THE STUDY . To study the impact of intermittent diaphragm and re-entrant WebTypical design of these decks is based on idealization of the diaphragm as a flexible element spanning laterally to (or across) effectively rigid lateral supports at frames and …
WebDec 4, 2024 · So on reentrant corners, basically 'L' shaped diaphragms, by flexible analysis you would have two collectors (beams) in the X and Y direction running the full length of the diaphragm at the bend in the L to accumulate the shear force and then a drag strut connector would be required to connect the collector to the shear wall in some way by …
