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...
Scattering of Waves by Steel Reinforcement in Concrete
The application of wave-sensing methods to the non-destructive evaluation of concrete structures requires often the use of simple (or at least tractable) models for the solution of 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...
Locally Buckled Plastic Hinge Behavior Under Monotonic and Cyclic Loading Condition
In order to clarify the influences of local buckling under monotonic and cyclic loading conditions, experimental studies were carried out on W8x10 A-36 structural steel members subjected...
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....
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
The Design of a Permanent Lunar Research Station
The advancement of the United States efforts in space exploration and research requires the establishment of a permanent manned lunar research station. This paper explores the possible...
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...
Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...
Microbiologically Induced Corrosion
Researchers investigating a building whose columns bled a colorless liquid found that the building was under attack by microorganisms. A community of bacteria had contaminated the fireproofing...
Fiber: Good For the Concrete Diet?
Fiber reinforcement of concrete has many advantages, but after thirty years of research those benefits have most often been seen in a laboratory. Some materials, such as synthetic fibers,...
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...
