  • Seismic performance and collapse assessments of reinforced concrete lateral- force resisting systems

    Creator:
    Buniya, Mustafa Kamil
    Abstract:
    Nonlinear response history analysis (NRHA) is increasingly becoming more accessible and prevalent in research and practice. As the accuracy of the NRHA results depends on the ground motion characteristics and the robustness of the numerical model, research has focused on the development of guidance for performance-based seismic design and assessment...

  • Evaluation of finite element techniques for soil reinforcement applications

    Creator:
    Berg, Ryan Robert
    Abstract:
    A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...

  • Lateral Load Path Analysis : Practical Methods for Light-Frame Modular Structures

    Creator:
    Huynh, Thanh Q.
    Abstract:
    The objectives of this study are to use SAP2000 to investigate lateral load paths and system behavior in a modular, light-frame wood structure by investigating different foundation configurations and to further develop and validate existing modeling techniques of shear wall elements based on the Perforated Shear Wall Method. The modeling...

  • Large scale model testing of the FMC submerged wave attenuation device

    Creator:
    Huber, David S.
    Abstract:
    This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

  • Evaluation of polymer modified asphalt in hot mix pavements

    Creator:
    Ifft, Charles
    Abstract:
    Polymer modified asphalts have recently been the focus of much attention in the U.S. due to claims that polymer additives will lengthen the life of an asphalt pavement. Much of the published research on this topic has been concentrated on the effects of polymer modifiers on binder and mixture properties....

  • Sand pumping efficiency of a water ejector apparatus

    Creator:
    Saguanwongse, Suvat
    Abstract:
    The purpose of this investigation is to study the effect of the solid transport capacity in pumping operation: A special type of jet apparatus was investigated which emits a water jet downward counter current to delivery flow, from inside of the suction pipe toward sediment to be excavated. Two sizes...

  • The Effects of Construction Practices on Concrete Construction Joint Performance

    Creator:
    Panduranga Setty, Shreyas
    Abstract:
    Concrete is the most widely used construction material in the world. When constructing large concrete structures, concrete may have to be placed in multiple lifts. In these cases, fresh concrete is placed on hardened concrete. The interface that is formed between these two lifts of concrete is known as a...

  • Cyclic performance of connections used in hybrid cross-laminated timber

    Creator:
    Mahdavifar, Vahid
    Abstract:
    One of the recent additions to the panoply of engineered wood products is cross-laminated timber (CLT). CLT is a prefabricated, large-scale, solid wood panel that consists of multiple layers of lumbers stacked together, with each layer arranged perpendicular to the next layer, glued with structural grade adhesives, and pressed. The...

  • Ambient current effects on vertical selective flow withdrawal in a two layer reservoir system

    Creator:
    Charbeneau, Randall Jay
    Abstract:
    Withdrawal from a two-layer flow field is examined in terms of the degree of selectivity of the withdrawal flow and its dependence on an ambient current. Selectivity is defined as the bias of withdrawing one layer more strongly than the other; the extreme' case is complete selective withdrawal, where one...

    Evans, Gary L.
    Abstract:
    The purpose of this report is to address the problem of supplying construction aggregates to Oregon's coastal areas that are currently, or will in the near future, be deficient of good quality materials. This is done primarily by studying methods of utilizing marginal aggregates that are abundantly available in the...
