Abstract: The bottom flutes of a fluted deck or diaphragm of a building are fixedly attached to a horizontal load bearing member supported by vertical load resisting members. A load translation member precludes relative movement between the top flutes en masse and the bottom flutes en masse. By precluding relative movement of the top and bottom flutes, the shear loads imposed upon the diaphragm by earthquakes and/or high winds are translated throught the load translation member and the load bearing member to the vertical load resisting members.

Abstract: A poured concrete building deck structure of the type having corrugated sheet metal form deck wherein the edges along sides parallel to the corrugations of the major form deck at the edges of the deck and edges of internal openings through the deck are formed by a corrugated sheet metal form having corrugations at about 90.degree. to the major portion of the corrugated sheet metal form deck, the ends of the deck around all sides of the building or around all sides of the internal opening being spaced a distance from the desired building line or opening and an edge bracket fastened to the outer ends of the sheet metal forms extending outwardly to the desired relationship to the building line or opening and providing a means to retain poured concrete.

Abstract: An improved concrete slab and steel construction wherein a pan is extended between adjacent joists, said pan having a bend line axially along its length, a portion of said pan resting a joist, a second portion being transversely notched such that said pan straddles adjacent joists at said notches, said pan serving to support poured in place concrete such that said concrete haunches down to supporting beams, thereby forming a composite concrete slab and steel structure.

Abstract: A corrugated sheet for use as part of a composite concrete deck comprising parallel spaced crest surfaces connected to parallel spaced soffit surfaces by upstanding connecting web surfaces that converge towards each other as they approach a common crest surface, all the crest, soffit and web surfaces being generally planar with at least the crest surfaces furthermore being provided with upstanding, continuous, longitudinally extending beads made from the crest surface material and with laterally extending upstanding projections running between the beads and connecting them together. The panels between the beads and the projections function as shear panels. An alternate embodiment provides shear panels that are slightly depressed with respect to the surrounding surface material, projections that have flat upper surfaces, and a panel edge portion that is shaped to enable the panels to be secured together in overlapping relationship.

Abstract: This invention relates to a sheet metal structural shape for use in building construction having a generally box shape with outwardly extending flanges at one end of the substantially parallel sides and inwardly extending flanges at the other end of the parallel sides forming a slot between the ends of the inwardly extending flanges and a closure between the ends of the outwardly extending flanges closing the space between the sides at that end. The sheet metal structural shape may be advantageously used as a structural shape in deck structures and in wall structures according to this invention. One deck structure of this invention uses the sheet metal structure shape as a sub-purlin, or purlin on short spans, supporting insulation on the bottom outwardly extending flanges and having sheet metal roofing material fastened to the inwardly extending flanges at the top end of the structural shape. Thus, a deck is provided with at least a major portion of the insulation beneath the steel roof decking.

Abstract: A sheet metal structural shape for use as a stud or mullion in wall construction or a purlin or sub-purlin in deck construction which is symmetrical about a vertical bisecting plane having a central vertical web, two diagonal legs projecting downwardly from one end of the web forming an included angle of about 30.degree. to about 90.degree., each of the diagonal legs having a leg projecting downwardly at its extremity in a plane substantially parallel to the web, each of the parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of the flanges enclosing the area formed by the diagonal sides, parallel sides and closure side, and a stiffening member at the other end of the web. A wall structure utilizing a spaced series of the metal structural shapes with a wall material attached to the flanges of adjacent structural shapes.

Abstract: A fluted deck for use in the building industry includes a plurality of vents disposed within the webs interconnecting top and bottom flutes. Since the webs are proportionally stronger than the top and bottom flutes, the vents do not reduce the inherent strength of the deck. The vents are inwardly oriented louvers longitudinally aligned with the troughs developed in the deck. When concrete fill is poured upon the deck and particularly when the concrete fill is covered by non-porous insulating material, the vents promote and insure more uniform and more complete curing than unvented deck. The inwardly directed louvers form recesses or depressions within the concrete fill to physically interlock the deck with the concrete fill and form a high strength unitary diaphragm for buildings.

Abstract: An impact-resistant wall structure is fabricated from two types of sheet metal cellular panel units and concrete columns which are enclosed thereby. Inner sheet metal cellular panel units are secured to outboard members of a building framework. Outer sheet metal cellular panel units are secured outboard to the inner sheet metal cellular units with the cells of the inner units perpendicular to the cells of the outer units. The inner sheet metal cellular units cooperate with the outer sheet metal cellular units to provide total peripheral metal enclosure for concrete columns. The outer sheet metal cellular units are fastened to the inner sheet metal cellular units at contiguous points preferably by means of threaded fasteners which extend into the concrete columns. Reinforcing rods positioned within the cells of certain or all of the panel units provide increased tension reinforcement, increased shear resistance, and produce local damage to impacting missiles.

Abstract: This invention relates to boardlike, load bearing, construction units formed from a tensile portion substantially uniformly distributed over the entire area thereof and which also has fastener holding properties and a cementitious material of good compressional strength forming substantially the remaining portion of the unit with novel means for effecting a bond between the tensile and compressional portions along with means for manufacturing the units and their use in various systems of construction.

Abstract: A composite slab assembly having an elongated metal deck provided with a number of longitudinally oriented upwardly directed integrally formed ribs and a concrete layer disposed on the metal deck with longitudinally oriented portions in complementary surface to surface engagement with the underlying metal deck. A transversely oriented integral reinforcing beam formed by a thickened portion of the concrete layer and having a lower extremity disposed below the level of the uppermost surfaces of the metal deck. The metal deck having at least one transversely directed discontinuity within which a portion of the transverse beam is received. Reinforcing rods may be provided in the integral reinforcing beam.The metal deck rib discontinuity may be partial and take the form of a number of longitudinally spaced notches generally aligned with similar notches in other ribs. The discontinuity may also be total with a complete transverse deck gap in the region of the beam.
