The mechanics of plastic-aluminum composite I-beams
… an initial investigation of the mechanics of I-beams developed with plastic-aluminum composite technology. Plastic-aluminum composites in structural beam/frame/truss elements are a relatively new concept that has seen little, if any, application in modern construction. This technology has …

Cyclic lateral-torsional buckling of short I-beams
… buckling and post-buckling behavior of short I-beams subjected to cyclically reversing loads. The eccentrically braced frame, used in the earthquake resistant design of building structures, provides an application in which lateral buckling of short I-beams under cyclic loading is relevant. Our …

Implementation of Infrared Non-Destructive Evaluation in Fiber-Reinforced Polymer Bouble-Web I-Beams
… fiber-reinforced polymers (FRP) in double-web I-beams (DWIB) to replace steel beams in bridge applications, there are many benefits along with the disadvantages. A bridge has been built with this new type of beam after only short-term proof testing for validation. Nondestructive evaluation (NDE) …

Neural Network Fatigue Life Prediction in Steel I-Beams Using Mathematically Modeled Acoustic Emission Data
… research is to predict fatigue cracking in metal beams using mathematically modeled acoustic emission (AE) data. The AE data was collected from nine samples of steel I-beam that were subjected to three-point bending caused by cyclic loading. The data gathered during these tests were filtered in …

Low Proof Load Prediction of Ultimate Strengths of Fiberglass/Epoxy I-Beams Using Acoustic Emission
… testing was used to monitor fiberglass/epoxy I-beams. The experiment consisted of loading the I-beams in cantilever fashion with a hydraulic ram. While testing, AE waveforms were collected from the onset of loading to failure. After acquisition, the AE data from each test were filtered to …

Experimental and Theoretical Investigations of a New Flat Slab System Incorporating GFRP Stay-In-Place Structural Forms and Embedded I-Beams
… (GFRP) I-sections as primary and secondary beams, with columns supporting the primary beams. GFRP stay-in-place (SIP) structural forms span the spacing between, and are bonded to, the lower flanges of the I-beams. Different components of the floor were investigated. Flexural behaviour in the …

An Investigation of Beam-to-Column Connections for Composite Structural Systems
I-beams with angle connections are becoming the standard framing method for composite structures. We claim that closed sections are often a more appropriate member selection. We also present the cuff connection; a novel beam-to-column connection element suited to closed structural members. We …

Web crippling of high strength cold-formed steel beams
… behavior of high strength cold-formed steel beams subjected primarily to web crippling was investigated analytically and experimentally. In this study hat sections and I-beams, formed from five different types of high strength sheet steels commonly used in the automobile industry, were …

A Solution for Commodity Field Hauling with Self-Unloading Semi-Trailers
… has a framework of ribs supported by two I-beams. This unique rib design combined with the main I beams act as large vertebra, which results in a rigid underbody that maintains flexibility and strength. Special consideration was taken while creating this design to account for dynamic loading …

Design analysis of single-span advanced composite deck-and-stringer bridge systems
… of cellular box decks and wide-flange I-beams as stringers is presented. The design analysis covers: (1) ply stiffnesses and strengths; (2) laminate engineering stiffnesses; (3) apparent stiffness properties for composite decks; and (4) stringer stiffness properties. Finite element …

Elastic Lateral Torsional Buckling of Beams Strengthened with Cover Plates while under Loading
… method for strengthening existing steel I-beams is to weld either one or two cover plates to the flange(s). In many cases, it is not feasible to completely unload the beam before carrying out the strengthening procedure. In these conditions, operators resort to strengthen beams while under …
