  • Response of guyed offshore towers to stochastic loads in the presence of steady current

    Creator:
    Brynjolfsson, Sigurdur
    Abstract:
    The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....

  • The application of a band variable-inertia flywheel to an urban transit bus

    Creator:
    Moosavi-Rad, Hamid
    Abstract:
    This dissertation investigates by means of computer simulation the potential of a Band Variable-Inertia Flywheel (BVIF) to store energy for an urban transit bus. Replacing both a fixed-inertia flywheel (FIF) and a continuously variable transmission (CVT), the Band Variable-Inertia Flywheel is capable of accelerating a vehicle from rest to a...

  • Three-dimensional experiments and modeling of anisotropic clay

    Creator:
    Anantanasakul, Pongpipat
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the stress-strain, volume change, shear band formation, and strength characteristics of normally consolidated anisotropic clay under fully three-dimensional stress states. A series of consolidated drained true triaxial tests with a constant mean effective stress and constant Lode...

  • Selection and performance evaluation of a test method to assess thermal cracking resistance of asphalt-aggregate mixtures

    Creator:
    Jung, Duhwoe
    Abstract:
    Thermal distress in asphalt concrete pavements is a widespread problem around the world. Thermal cracking can be divided into two modes of distress: low temperature cracking and thermal fatigue cracking. Low temperature cracking results from extremely cold temperatures; thermal fatigue cracking results from daily temperature cycles. Low temperature cracking is...

  • Robust controller design for robotic manipulators with saturation

    Creator:
    Liang, Zuyang
    Abstract:
    The development of modern industries calls for the robotic manipulators with high speed and accurate tracking performance. Many authors have paid attention to robust control of robotic manipulators; however, only few authors have also considered the control problem of manipulators with power limitation. In this dissertation, the robotic manipulator is...

  • Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

    Creator:
    Senturk, Ahmet Ekin
    Abstract:
    Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

  • A study of compression loading of composite laminates

    Creator:
    Berbinau, Pierre J.
    Abstract:
    The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

  • A composite-beam finite element for seismic analysis of wood-framed buildings

    Creator:

    Abstract:
    A computer program called SAPWOOD which possesses the capability of performing linear or nonlinear, static or dynamic response including seismic excitation for wood-framed buildings with semirigid connection systems is presented in this study. Program SAPWOOD is a modification of the program NONSAP by adding new elements such as a linkage...

  • Parametric uncertainties in reliability analysis of bridge structures

    Creator:
    Hamutcuoglu, Osman Murat
    Abstract:
    Probability-based reliability methods have placed an increased emphasis on realistic simulation of structural behavior in bridge engineering. Uncertainty is present in every aspect of structural analysis. Aleatory uncertainties in the loading and load-carrying capacities, and epistemic uncertainties in mathematical idealization of bridge systems are the major contributors to uncertain structural...
