Honeycomb fiber-reinforced polymer sandwich composites for development of aquaculture raceway systems
It is argued that the utilization of impaired mine waters abundant in WV and other mid-Appalachian states for fish culture can substantially increase aquaculture economic development. The primary limitation to the effective utilization of discharged waters is the lack of suitable fish culture tanks …

Concrete Innovation Museum: A Symphony of Liquid Stone and Light
This thesis explores how diverse concrete construction methods—cast-in-place, precast, concrete blocks, and 3D concrete printing—can be integrated to shape spatial experience, manipulate sunlight, and enrich architectural expression. The project is sited in DuSable Park, a 3.4-acre remediated site …

Refinement of the Inverted T-Beam Bridge System for Virginia
The inverted T-beam bridge system is a bridge construction technique that follows accelerated bridge construction processes. The system was discovered in France and first adopted in the U.S. by the Minnesota Department of Transportation. In 2012 the system was modified and adopted by Virginia, with …

Fiber-Reinforced Polymer Bridge Girders for Extremely Aggressive Environments
<p>In 2012, the federal government estimated that $17.5 billion was spent on inspection, rehabilitation, maintenance, and replacement of the nation’s bridges. While the average lifespan of steel and reinforced concrete bridges is 50 years, certain bridges subjected to extremely aggressive marine …

Integration of Zip-formwork and conventional formwork systems for shape-optimized concrete in large scale construction
Cast-in-place concrete production plays a dominant role in the architecture, engineering and construction (AEC) industry, particularly in large-scale projects, contributing significantly to global material consumption, construction costs, and embodied carbon emissions. Shape optimized concrete has …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Inverted T Beam System
The inverted T-beam system provides an accelerated bridge construction alternative. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking and reduces the likelihood of cracking due …

An Architecture of Light: A Catholic Church for Blacksburg, Virginia
This thesis is an investigation on how in architecture structure and material modulate the perception of light. This idea was implemented in the design of a catholic church for the parish of Blacksburg,Virginia. The vision of the church as a community in constant interaction resulted in the design …

Slab-on-girder prestressed concrete bridges: linear and nonlinear finite element analysis and experimental load tests
“A diaphragm is a transverse stiffener, which is placed between girders in order to maintain section geometry”, (AASHTO, 2002). Intermediate diaphragms, usually placed at the midspan or third points of a bridge, are thought to contribute to the overall distribution of live loads in bridges. …

Global and local performance of prestressed girder bridges with positive moment continuity detail
… behavior of prestressed girder bridges made continuous by adding continuity diaphragms with a recently proposed positive moment continuity detail were investigated in this study. The focus of the investigation is on the positive moment caused by temperature gradients, time dependent effects such …

Prestressed PCBT Girders Made Continuous and Composite with a Cast-in-place Deck and Diaphragm
… prestressed PCBT girders made composite with a cast-in-place concrete deck and continuous over several spans through the use of continuity diaphragms. The current design procedure in AASHTO states that a continuity diaphragm is considered to be fully effective if a compressive stress develops in …
