Evaluation of deck fasteners functioning as shear connectors for composite steel joists
… as shear connectors for composite open web steel joists is studied. Results of thirty-six push-off tests are evaluated in terms of strength and behavior. Six types of deck fasteners are considered. They are: 1. #12-24 Teks/5 self-drilling, self-tapping screws. 2. 1/4-14 Teks/3 with a 1 1/4 …

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 …

Feasibility Study of Partially Restrained Connections
… throughout the element. Combining this idea with steel joists, which are also quite common in construction, makes for shallower story heights and lower steel weights. This initial study analyzes partially restrained connections for both hot rolled shapes and steel joists using non-composite and …

Elastic-plastic finite element modeling of long span composite joists with incomplete interaction
… 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 steel joists were …

Innovative accessible sunken floor systems for multi-story steel buildings
… accessible sunken floor systems for multi-story steel buildings with proliferating data cables and mechanical equipment. The terminology of an accessible sunken floor system or a dropped floor system is not new. Sunken floor has been used in reinforced concrete buildings with flat slabs and …

Evaluation of long span composite joists
… 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 shear connection was …

Evaluation of a proposed vibration criterion
… floor system consisting of a concrete slab on steel joists or beams is susceptible to annoying vibrations caused by walking. This investigation considers a criterion developed by Allen (1991) that indicates whether a proposed structural floor system is acceptable for walking vibrations. The …

Experiments on Cold-Formed Steel Beams with Holes
… were performed on 68 C-section cold-formed steel joists with unstiffened rectangular web holes. Four Steel Stud Manufacturers Association (SSMA) cross-section types; 800S200-33, 800S200-43, 1000S162-54, and 1200S162-97, were evaluated to explore the influence of holes on local, distortional, …

Numerical and Experimental Investigations on Static Behaviour of Composite Cold-Formed Steel and Timber Flooring System
Currently, the use of Cold-Formed Steel (CFS) joists with timber-based floorboards for constructing lightweight flooring systems in residential buildings is widespread. However, the potential benefits of composite action that arise due to the interaction of the top flange of cold-formed steel joist …

Floor Vibrations: Girder Effective Moment of Inertia and Cost Study
… in floors supported by widely spaced LH-series joists. Eight purpose-built floors of the type in question were subjected to experimental tests of girder effective moment of inertia and girder frequency. Frequencies were tested for two live loading cases. Three separate test configurations were …

A Framework for Cyclic Simulation of Thin-Walled Cold-Formed Steel Members in Structural Systems
… seismic analysis framework for cold-formed steel (CFS) framed-buildings supported by hysteretic nonlinear models for CFS members and screw-fastened connections. Design of CFS structures subjected to lateral seismic forces traditionally relies on the strength of subassemblies subjected to …
