The goal of this research 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 ...

In recent years the idea of using partially restrained connections in building structures has become more practical and economical. Partially restrained connections resist moment and also allow rotation, therefore distributing ...

The purpose of this study is to evaluate the performance of the 5/16 in. diameter Elco Grade 8 standoff screw as a mechanical shear connector in composite joists. Standoff screws are being investigated as an alternative ...

The majority of residential construction and a significant portion of light commercial and industrial construction has been, and will continue to be light-framed timber construction. In recent years, innovations have ...

<p>Shear lag is a non-uniform distribution of stress resulting when all cross sectional elements are not directly connected. This phenomenon renders the cross section only partially effective in resisting tensile loads. ...

With the development of lightweight steel beam and steel joist-concrete slab floor systems, floor vibration problems are becoming more and more prevalent. This paper presents the experimental and analytical study of the ...

A FORTRAN computer program applying the ultimate strength/instantaneous center of rotation method was written to generate the eccentricity coefficients used for the study of this project. <p>For single line bolted connections, ...

Sophisticated design techniques such as partially restrained connections need detail information on the load-deformation response of bolted connections. The behavior of single bolt, single shear connections are studied. ...

A lightweight 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 ...

<p>The strength 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 ...
