Effect of subduction zone earthquakes on SDOF bridge models

Creator:: Long, Yicheng
Abstract:: Current bridge design codes do not account for the effects of duration of mega-thrust subduction zone earthquakes. Furthermore, codes and even recent performance-based design methodologies only make use of the peak response quantities (forces, displacements, and ductility demands) and do not account for the increased number of inelastic cycles that...

In-Plane Shear Performance of Cross-laminated Timber and Cross-laminated Timber Concrete Composite Diaphragm Connection Systems

Creator:: Taylor, Brad
Abstract:: Cross-laminated timber (CLT) panels have been gaining popularity as diaphragm elements in mid- to high-rise construction projects. In addition, CLT-concrete composite (CCC) diaphragms have been implemented to expand the use of CLT diaphragms. To understand the behavior of CLT and CCC diaphragms, this research effort sought to characterize the cyclic,...

Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

Creator:: Anderson, Christopher H.
Abstract:: Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...

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...

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...

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...

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...

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...

Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

Creator:: Loving, Carly K.
Abstract:: To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...
