Interaction Effects in the Hybrid Control of Euler-Bernoulli Beams
The effect of viscous and Voigt damping upon the open loop response of simple continua such as Euler-Bernoulli beams is well understood. However, when attempting to control a distributed...
The Generalized Brazier Problem for Orthotropic Straight Tubes of Finite Length
A new engineering approach, based upon a mixed variational functional, is presented for the analysis of the nonlinear static behavior of thin-walled, circular-cross-section cylindrical...
Experimental Investigation of Bending and Twisting Coupling in Thin-Walled Composite Beams
The behavior of a thin-walled ppen section composite material beam depends on the anisotropic mechanical properties of the panels that form the beam. A beam theory has been proposed for...
Eigenproperties of a Twisted, Nonuniform Rotating Beam by the Finite Element Method
A initially twisted blade with nonuniform properties along the length, is rotating with constant angular velocity about an axis perpendicular to it's elastic axis. The blade is modeled...
Evaluating Damage Detection in Bridges
Several researchers have recently considered using vibration monitoring of highway bridges as a means for detecting structural deterioration. Results to date have demonstrated that the...
Flexural and Shear Studies of Carbon Fiber Reinforced Beams
This paper presents the results of laboratory test on beams reinforced with three dimensional continuous carbon fiber grid. The grid is prefabricated by three-dimensional weaving and epoxy...
Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...
Stresses in Open Section Fiber Reinforced Composite Beams Under Constant Shear Loading
A strength of materials approach from the ply level is used to derive expressions for stresses in statically determinate open section composite beams subjected to constant shear loading....
Measuring Vibration in an Advanced Composite Beam with Localized Internal Fiber-Optic Strain Sensors
Two optical fibers embedded with different configurations were used separately as strain sensors to measure the natural frequencies and modal amplitudes of a cantilevered graphite/bismaleimide...
Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
Pseudo-Simulation Method for Stochastic Problems
A new numerical method for problems of stochastic mechanics and other areas involving a small number of random parameters is presented. It is analogous to the Monte-Carlo simulation method...
Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...
Spatial Variability Effects on the Seismic Response of Models of Bridges
The significance of the spatial variability (spatial incoherence and apparent propagation) of the seismic ground motions on the response of bridges, modeled as three-span symmetric beams,...
Reliability Consideration in Shakedown Analysis
Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual...
Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
Feasibility of FRP Molded Grating-Concrete Composites for One-Way Slab Systems
This paper describes the behavior of one-way concrete slabs reinforced with Fiberglass Reinforced Plastic (FRP) molded grating. FRP molded grating is commercially available and is mainly...
Hybrid (FRP+Steel) Reinforcement for Concrete Structures
The most popular method to prevent corrosion of steel rebars and prestressing tendons is epoxy coating. This paper presents an alternative approach consisting in the combination of a fiber-reinforced-plastic...
Behavior of Concrete-Graphite/Epoxy Sections in Composite Bridge Girders
The focus of this work is on the behavior of composite bridge girders constructed from carbon-fiber-reinforced-plastic sections and concrete slabs. The study examines four-point bending...
Structural Performance of Hardwood-Metal Composite Beams
This research examines the deflection characteristics of layered timber/steel composite beams with hopes of applying such principles to large timber structures such as highway bridges....
Tunnel Takes Cathodic Protection
Cathodic protection is nothing new for bridges and parking garages, but it has never been installed in a tunnel�until now. As part of a $15 million rehabilitation project, the method is...
