  • 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...

  • Post-Earthquake Performance Assessment of Steel Strongback Braced Frames

    Creator:
    Rhoades, Katharine
    Abstract:
    Traditional braced frames are an efficient and economic means of resisting seismic demands. However, braced frames are prone to story mechanisms, which can result in concentrations of demands and damage during seismic events. Including steel strongbacks in conjunction with traditional braced frames can mitigate story mechanisms. The SBF results in...

  • Numerical Analysis of a Spine as a Retrofit of a Moment-Resisting Frame

    Creator:
    Rivera Torres, David M.
    Abstract:
    Steel moment-resisting frames (MRFs) are widely used in the United States to resist seismic forces. MRFs have many advantages, including architectural versatility, vetted member and connection detailing requirements, and high ductility for special MRFs (SMRF). However, MRFs require large members to meet story drift criteria. Moreover, strong-column-weak-beam requirements can result...

  • Coupled Eulerian-Lagrangian Finite Element Modeling Approach Applied to Wave Structure Interaction: Effects of Shielding, Channeling, and Wall Removal

    Creator:
    Al-Sayhood, Zeyad A.
    Abstract:
    The impact of tsunamis on coastal structures gained great a new impetus following the 2004 Indian Ocean Tsunami and the 2011 Tohoku earthquake and tsunami. While several experimental programs have been performed to gain a fundamental understanding, numerical models are needed to study additional features that cannot all be tested...

  • Improving Braced Frame Modeling Application

    Creator:
    Groshong, Corey
    Abstract:
    This work analyzes the numerical curvature of buckling braces. An existing brace modeling learning tool, which in its current state allows users to change the inputs within a simulated model of a braced element, was modified to display the curvature diagram. The curvature diagram was verified through comparison to existing...

  • Optimization of Construction Equipment Efficiency and Cost using Simulation and Field Data

    Creator:
    Kumar, Deepak
    Abstract:
    Unlike other industries, overall efficiency of construction projects has been growing minimally which directly causes cost overruns of projects. Though reducing idle time and increasing operational efficiency of construction equipment could result in significant cost saving, there is lack of practical knowledge of adjusting operational efficiency and integrating cost and...

  • Practical Design Considerations for Steel Slit Panel Frames

    Creator:
    Parikh, Madhav
    Abstract:
    Steel Slit Panel Frames (SSPFs) are an innovative and resilient lateral force resisting system. Steel Slit Panels (SSPs) are bolted to the beams and act as replaceable seismic fuses, dissipating energy through flexural yielding in links between vertical rows of slits. SSPFs have shown promise as a lateral force resisting...

  • Evaluation of ground motion duration effects on the damage prediction of building and bridge structural and soil-structural systems

    Creator:
    Belejo, Andre
    Abstract:
    The role of ground motion duration on the seismic performance of civil engineering structures remains unclear. Thus, the role of earthquake strong ground motion duration is assessed in a three manuscript thesis, which includes: (1) assessment of the effects of ground motion duration on the seismic performance of a model...

  • Crack Penetration and Deflection Behavior at Interfaces

    Creator:
    Alam, Mahabub
    Abstract:
    This study computationally and experimentally examines the mechanisms of crack penetration, deflection and the transition between penetration and deflection. The finite element analysis based computational modeling work used strength-and-energy based cohesive-zone approach to study the effect of dimensionless parameters (e.g., interfacial incident angle, fracture-length scale, and normalized toughness) on penetration/deflection...

    Slaven, Kelli R.
    Abstract:
    The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...
