  • Numerical Characterization and Modeling Uncertainty of Frame-Spine and Frame-Spine-FLC Full-Scale Specimens Tested at E-Defense Shake-Table

    Creator:
    Astudillo, Bryam
    Abstract:
    The characterization of the seismic performance of structures relies on numerical simulations. However, estimates of seismic response are subject to various sources of uncertainty, including modeling uncertainty. This research estimated the response of two full-scale structural specimens composed of a moment resisting frame, elastic spines, and force-limiting connections (FLC), which...

  • Use of benthic sediments as indicators of marina flushing

    Creator:
    Noble, Scott Morgan
    Abstract:
    This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...

  • An Integrated Conceptual Framework for Sustainable Public Housing

    Creator:
    Sharafeddin, Asma
    Abstract:
    Public housing (PH) provides a substantial portion of the housing in both developed and less developed countries, and the demand for it is increasing. The PH projects, however, are facing many challenges that are affecting their performance and cause their failures. The United States has demolished large portions of their...

  • Reliability-based Serviceability Limit State Design Procedures for Shallow Foundations

    Creator:
    Huffman, Jonathan C.
    Abstract:
    Reliability-based geotechnical foundation design focusses on soil and structure analysis that meets necessary safety, performance and/or serviceability criteria, calibrated based on probabilistic analyses and an accepted level of risk. As the civil engineering community seeks to better harmonize geotechnical and structural design methodologies, reliability-based design is being incorporated more into...

  • Construction risks allocation : optimal risk allocation decision support model

    Creator:
    Alsalman, Ali Abdullah
    Abstract:
    It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

    Creator:
    Li, Wennan
    Abstract:
    The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...

  • Performance-based seismic design of light-frame shearwalls

    Creator:
    Kim, Jun Hee
    Abstract:
    Performance-based design has gained interest in recent years among structural designers and researchers. Performance-based design includes selection of appropriate building sites, structural systems and configurations, as well as analytical procedures used in the design process, to confirm that the structure has adequate strength, stiffness and energy dissipation capacity to respond...

  • Steel confined yielding damper for earthquake resistant design

    Creator:
    Newell, James D.
    Abstract:
    An experimental study of a passive energy dissipation tension-compression yielding brace or buckling restrained brace has been conducted. The Confined Yielding Damper (CYD) consists of a steel yielding core confined within a tube filled with non-cohesive media. The external tube and confined non-cohesive media provide lateral stability to the core...

  • Are watershed management plans selected and preferred by stakeholders considering current climate conditions robust against climate change scenarios? A sensitivity study of stakeholders spatially-explicit preferences

    Creator:
    Cannady-Shultz, Kenneth R.
    Abstract:
    In the light of the changing climate, the importance of designing effective watershed management plans that are likely to be implemented is becoming ever more important. This research introduces a new concept, consensus, for incorporation into stakeholder-guided interactive optimization of watershed management plans. User preferences were mathematically simulated based upon...
