Defining and comparing risks and success measures of the reference design process and traditional new product development processes

Creator:: Larson, Tasha M.
Abstract:: To address aggressive global competition, retain customers and increase revenue, firms are required to pursue New Product Development (NPD) projects. Ventures of this nature are risky and fail often. Numerous factors influence the survival of a project. In this research, 16 factors have been identified and selected as indicators of...

Chloride Binding of Portland Limestone Cement containing Supplementary Cementitious Materials

Creator:: Then, Nathalene WY
Abstract:: Chloride binding in Portland limestone cements (PLC) can be attributed to the chemical reaction between chloride ions and carboaluminate phases to form Friedel’s salt and the physical interaction between chloride ions and calcium-silicate-hydrates (C-S-H). This thesis examines the chloride binding of mortar samples containing varying amounts of limestone, fly ash,...

Equilibrium and Non-equilibrium Thermodynamic Modeling of Cement Pastes Containing Supplementary Cementitious Materials

Creator:: Glosser, Deborah B.
Abstract:: Thermodynamic modeling of cementitious material is an established tool for predicting the hydrated phase assemblages, pore solution pH, and pore solution composition of mixtures of various chemical compositions and water-to-binder (w/b) ratios. However, traditional thermodynamic techniques have major limitations for modeling mixtures containing supplementary cementitious materials (SCM), and when modeling...

Seismic Performance of Aging Prestressed Transmission Pole with Simulated Soil Foundation

Creator:: Argo, Maximo
Abstract:: The Cascadia Subduction Zone has recently been identified as a source for an impending great earthquake. The potential of a large earthquake has created widespread interest into the resiliency of lifelines within the potentially affected areas. One critical lifeline is the electrical distribution and transmission systems which relies on legacy...

Sustainability of Concrete in the Pacific Northwest

Creator:: Chaimov, Hilary
Abstract:: Reducing the CO2 emitted by the production of cement can greatly reduce the carbon emissions attributable to the built industry. By specifying concrete mixes with lower global warming potentials (GWPs), structural engineers can reduce the carbon emissions of concrete used in the built industry. This thesis uses a cradle-to-gate life...

Methods for strengthening flexural steel details in reinforced concrete bridge girders using a near-surface mounted retrofitting technique

Creator:: Amneus, Deanna
Abstract:: Many older reinforced concrete deck girder (RCDG) bridges contain straight bar terminations of flexural reinforcement. Common bridge design practice of the 1950s did not consider the additional demands on the terminated bars from shear and flexure. Moreover, more stringent code specifications and heavier permit trucks contribute to the insufficient ratings...

Seismic performance of diagrid steel structures using single and double friction mass dampers

Creator:: Ramadhan, Garlan
Abstract:: The steel diagrid structural system is a recent load bearing and lateral resisting structural system for tall building structures that is relatively unexplored in the western United States. One possible reason for the little use of diagrid systems in earthquake prone regions is the lack of guidelines and application examples...

Development of a new mixture proportioning method and assessing the influence of material characteristics on flowing concrete mixtures

Creator:: Hendrix, Greg
Abstract:: Cast-in-drilled-hole (CIDH) piles are often constructed to depths that are inaccessible to internal vibration of the concrete. Internal vibration is necessary to consolidate the concrete and, if not performed, then typically inspection pipes are necessary to detect the presence of voids in CIDH piles. Void detection is critical to assessing...

Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:: Barker, Laura
Abstract:: Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

The influence of seismic attack and chloride-induced corrosion on a life cycle inventory assessment of different concrete mixtures

Creator:: Christiansen, Joshua W.
Abstract:: The life cycle assessment (LCA) process is a systematic approach to determining the environmental impacts of different products and processes. LCA is a relative approach that requires functional equivalence for the results to be compared. A method is presented that achieves functional equivalence by equating the reliability indexes being compared....
