Interpolation between values shown is acceptable. 0 calculates diaphragm shear, flexibility factors and uplift resistance for steel deck roof and floor systems. Where welds are shown at the supports in the "DECK" worksheet, SDI recommends using welding washers only on deck thickness less than 0. Columns and deck not designed to resist longitudinal bending (very flexible). A Precast concrete deck is made of precast hollow-core concrete slabs that are supported by steel beams. gauge of steel decking, concrete type and mix, and placement of reinforcing are then determined. Deflection under specified live load not to exceed 1/240 of span, except that when gypsum board ceilings are hung directly from deck, live load deflection not to exceed 1/360. Concentrated Loads A line load running parallel to the span should be treated as a series of concentrated loads. Our online tools will help you select the most cost effective steel decking for your project, including roof deck, floor deck, composite deck, and dovetail deck.
