The "K" Series joist web is a single bent bar running zig zag between top and bottom chords. The minimum bearing re- quirement on masonry for a K-series joist is 4 inches, If the joist is detailed to be anchored to a steel bearing plate, the plate must be at least 6 inches wide . If the compression in the top chord of the open-web joist due to partial connection exceeds the buckling capacity of the top chord then the buckling capacity governs the design. Open-web steel joist design is governed by CSA S16-01, under section 16. While this example illustrates the design of a wood diaphragm, a similar methodology is applicable to untopped steel deck diaphragms. Roof diaphragm design.
