Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

Creator:: Lostra, Mackenzie M. W.
Abstract:: Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...

Performance Based Tests on Cross Laminated Timber - Concrete Composite Floor Panels

Creator:: Blank, Curtis
Abstract:: This project determines the short term and long term effective stiffness values for Cross Laminated Timber (CLT) with a reinforced concrete topping. The reinforced concrete was attached to the CLT panels with interface connections, and different types of interface connections were tested. Throughout this project, there are 31 tests with...

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...

Finite Element Modeling Strategies for Seismic Collapse Assessment of Non-planar Slender Reinforced Concrete Structural Wall Resisting Systems

Creator:: Mohammed, Mohammed A.
Abstract:: For mid-rise and high rise buildings, slender reinforced concrete (RC) structural walls are commonly used as the main structural elements to resist lateral applied loads in high seismically areas around the globe. These RC structural walls can provide substantial deformation capacity, stiffness, and lateral strength through the contribution of their...

Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

Creator:: Mahr, Kolton J.
Abstract:: Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...

Multi-hazard Damage and Loss Assessment of Bridge Networks

Creator:: Burns, Patrick O.
Abstract:: The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

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...

Effects of Moisture Intrusion on the Performance of a Cross-Laminated Timber (CLT) Angle Bracket Connection

Creator:: Bora, Shrenik S.
Abstract:: Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...

High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

Soil-bridge interaction during long-duration earthquake motions

Creator:: Romney, Kyle T.
Abstract:: Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...
