WebJan 21, 2024 · As a side question, you mentioned that when using collectors like the ones shown in blue, they tend to run the collector back full width across the diaphragm in order to use the main diaphragm's back … WebThere still needs to be a chord at gridline C for that diaphragm when loaded in the left-right direction. The collector is for dragging the load into the shear wall when you are analyzing lateral load in the up-down direction. Sometimes, a member can act as a collector in one direction and a chord in the other. WebDiaphragm boundary elements (chords and collectors) are often glulam timber beams. Connections at the ends of timbers serving as boundary elements must be detailed to resist the axial forces induced into them to maintain the continuity of the chords. sharlayan aether oil ff14

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 Figure 1.)
