Standoff Screws Used In Composite Joists
… screw as a mechanical shear connector in composite joists. Standoff screws are being investigated as an alternative to welded shear studs in short span composite joists. The data and results obtained from 106 pushout tests performed on the Elco Grade 8 standoff screw are presented. The …

Evaluation of long span composite joists
… and stiffness characteristics of longspan composite open-web steel joists are studied. Eight full scale single span composite joists were tested to failure to evaluate their performance in both the elastic and inelastic ranges. The test specimens' spans, depths, slab depth, and amount of …

Strength Calculation Model for Standoff Screws in Composite Joists
… the use of this shear connector in design of composite floor systems. The study considers results from push-out tests using this type of screw reported by Hankins et al. (1994), Alander et al. (1998), Webler et al. (2000), and Mujagic et al. (2000). Further, this study identifies the …

Standoff screws functioning as mechanical shear connectors in composite joists
The results of sixty-five double-sided pushout tests utilizing the Elco grade 8, 5/16 in. diameter, standoff screw functioning as a mechanical shear connector are presented. In all tests, the base material, through which the screw was fastened, was fabricated out of back to back angle to simulate …

Strength of welded headed studs in ribbed metal deck on composite joists
Standards for stud strength in composite joists are presently not available. Existing standards for composite design are targeted for composite beam design while design of a composite joist requires more emphasis on stud strength to fully develop the joist bottom chord. Stud placement in the deck …

Elastic-plastic finite element modeling of long span composite joists with incomplete interaction
… finite element analyses of seven long span composite open-web steel joists. These analyses account for the incomplete interaction between the concrete slab and the steel joist by modeling the nonlinear behavior of the steel shear connectors. Experimental tests on long span composite open-web …

Investigation of Ultimate Strength of Composite Open-Web Joist-Girders
… was to study several methods of generating composite action using open-web joist-girders, designed and manufactured by Nucor Corporation. In addition to comparing the relative performance of these systems, it was intended to determine whether the current accepted design procedure for …

Ultimate strength analysis of partially composite and fully composite open-web steel joists
The behavior of composite steel joists with various degrees of shear connection is investigated. The results of eight full-size composite joist tests, conducted as a portion of the study, are presented. Joist spans range from 24 ft. to 30 ft. and depths from 8 in. to 18 in. Six types of mechanical …
