Static and Wave Equation Analyses and Development of Region-specific Resistance Factors for Driven Piles

Creator:: Bougataya, Youssef
Abstract:: This study uses an existing database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation are used to develop an effective stress-based...

An Evaluation of the Random-Parameter and Latent Class Methods for Heavy Vehicle Injury Severity and Crash Rate Analysis : An Idaho Case Study by Roadway Classification

Creator:: Anderson, Jason
Abstract:: This thesis provides a comparison of advanced econometric frameworks to account for unobserved factors in crash reported data (also referred to as unobserved heterogeneity) while identifying contributing factors by roadway classification for heavy vehicle injury severity and crash rates. The presented thesis provides two manuscripts that expand the literature regarding...

An Experimental and Numerical Investigation of Tall Mechanically Stabilized Earth Walls

Creator:: Strahler, Andrew W.
Abstract:: The implementation and construction of Mechanically Stabilized Earth (MSE) walls has undergone substantial expansions in recent years, owing to its relatively low cost, ease of construction, and high efficiency compared to conventional retaining methods. As a result, MSE walls are being constructed to greater heights with complex features (e.g. multiple...

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...

Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

Multiobjective Optimization of Wetlands for Attaining Flood, Water Quality and Bird Habitat Benefits

Creator:: Noa-Yarasca, Efrain
Abstract:: A significant number of historically existing wetlands that naturally stored rainwater and attenuated flood peaks have now been drained and employed as new farming areas. Beyond the water quality and flow problem, this has resulted in loss of natural habitats of diverse ecological species. Restoring wetlands have hence been proposed...

Accuracy Evaluation of Real-Time GNSS Survey Observations

Creator:: Allahyari, Mahsa
Abstract:: Real time networks (RTNs) have become popular for Global Navigation Satellite System (GNSS) surveys because highly accurate positions can be derived in seconds to minutes compared to hours as required with static sessions. To evaluate the accuracy of these shorter-duration, RTN GNSS observations and their potential for use as a...

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...

Student Engagement : Exploring How and Why Students Engage In- and Out-of-Class

Creator:: Pascoe, Jason J.
Abstract:: Student engagement in a course plays a vital role in a student’s ability to process and construct knowledge. Student engagement research has investigated how students engage in and out of the classroom on a macro scale, through observation and survey data collection of large student populations, which lack focus on...

Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

Creator:: Gillins, Matthew N.
Abstract:: Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...
