Diaphragm chord and collector
Did you know?
WebHome National Institute of Building Sciences 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.
WebBoundary elements for diaphragms include chords, collectors, their splices, and their connections to the vertical lateral force-resisting system (VLFRS). Boundary elements in CLT diaphragms can include steel straps, framing components supporting the CLT such as steel or timber beams, or the CLT panels themselves. WebAnswer: The collector forces within a floor diaphragm m= ay be measured through the following process: Define a semi-rigid diaphragm, then apply diaphragm forces, as shown= in Figure 1: ... Figure 5 - Compression and tension chord forces. For shear and collector forces located at the connection between the= diaphragm and a shear wall, draw or ...
WebBecause the panelized wood roof diaphragm in this building is idealized as fl exible, lines A, B, and E are considered lines of resistance for the east-west seismic forces. A collector is needed along line B to drag the tributary east-west diaphragm forces into the shear wall on line B. The loading and shear diagrams are shown in Figure 2-4. WebIf adequate connection is made between the band joist and the wall top plate, then the diaphragm sheathing, band joists, and wall framing function as a composite chord in resisting the chord forces. Thus, the …

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.
