Energy harvesting from wind-induced vibration of suspension bridges
… weight of 2 kg is proposed to be installed on a suspension bridge deck to harvest energy and to control the motion of the bridge deck. The feasibility of the installation of the device is studied with respect to the amount of energy that could be harvested. The commercial software SAP2000 was …

The application of parallel computer technology to the dynamic analysis of suspension bridges
… onset of aerodynamic instabilities in long span suspension bridge structures, such as flutter which is a catastrophic aeroelastic phenomena. The thesis is set out in two distinct parts:- Part I, presents the theoretical background of the main forms of aerodynamic instabilities, presenting in …

Aerodynamic stability of bridges
… of research on the Aerodynamic Stability of Suspension Bridges. Wind has wrecked suspension bridges for over a century but the underlying cause, an increasing harmonic amplitude due to wind, has been ignored until recently. For many years bridges have been designed to withstand horizontal …

Investigation of a grid induced turbulent environment for wind tunnel testing
… turbulent flows for testing sectional models of suspension bridges is discussed. The power spectra of the turbulence was found to agree quite well with the von Karman spectrum equation for atmospheric turbulence. The integral length scales were found to increase with increasing distance …

Verificação experimental de um novo sistema estrutural para pontes de grandes vãos
… uses an association of general principles of suspension bridges and concrete bridges. An ultimate load test on a model of a "beam with hanging effect" was performed, and the results are presented in tables and graphs and are briefly discussed and compared with analytical values. The performed …

Wired for Business: The Roebling Story.
… Roebling's innovation in wire-rope, modern suspension bridges, high-rise elevators, construction cranes, and cable cars would not have been possible. Yet historians have virtually ignored Roebling and other civil engineers, entrepreneurs, and inventors who built America's infrastructure. …

Carbon nanotubes and their application to very long span bridges
… fast-expanding, the overall design of long span bridges has not progressed significantly, and the increase in span chiefly depends of new materials. Carbon nanotubes, with their extraordinary Young's modulus and tensile strength far exceeding steel, allow the production of ultra-strong cables …

Orb weaver capture thread biomechanics and evolution
… fibers bow and the droplets extend, forming a suspension bridge configuration whose biomechanics sum the adhesion of droplets and dissipate the energy of struggling insects. Given this performance, the second study predicts that the material properties of both thread components have evolved in …

Microstructure and mechanical properties of cold drawn steel wires
… used for a variety of applications, such as suspension bridges, steel cords for automobile tires, and springs. Much research has been done to increase their mechanical strength. With advances in modern production technology, both the drawing speed and the quality of drawn steels have been …

Experimental and numerical investigations on wind characteristics and wind induced vibrations of bridge structures
… and more flexible structures such as long span bridges and suspension bridges are built in the world, their increased flexibility can cause serious concerns for researchers and engineers. For such structures, wind load has become one of the most important dominant loads under consideration in …
