Investigation of Ultimate Strength of Composite Open-Web Joist-Girders
(Virginia Tech, 1999-09-16)
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 ...
Feasibility Study of Partially Restrained Connections
(Virginia Tech, 1997-02-10)
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 ...
Standoff Screws Used In Composite Joists
(Virginia Tech, 1998-05-05)
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 ...
Monotonic and Cyclic Performance of Structurally Insulated Panel Shear Walls
(Virginia Tech, 1997-12-10)
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 ...
Investigation of the shear lag coefficient for welded tension members
(Virginia Tech, 1989-12-05)
<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. ...
Vibration characteristics of joist and joist-girder members
(Virginia Tech, 1996-05-15)
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 ...
Predictive equations for bolted connections
(Virginia Tech, 1990-02-14)
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, ...
The load deformation response of single bolt connections
(Virginia Tech, 1995-09-05)
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. ...
Evaluation of a proposed vibration criterion
(Virginia Tech, 1992-05-05)
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 ...
Evaluation of long span composite joists
(Virginia Tech, 1990-12-15)
<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 ...
