Additive Manufacturing Of Engineered Cementitious Composites With Ultra-High Tensile Ductility, Amir Bakhshi

Civil Engineering ETDs

One of the critical factors in the development of additive manufacturing in the construction industry is designing suitable materials for 3D printing applications. 3D concrete printing (3DCP) has gained significant attention due to the abundance and availability of concrete. However, concrete is a brittle material and, without proper reinforcement, cannot meet the requirements for structural purposes. Engineered Cementitious Composites (ECC), known for high ductility, and strain-hardening with low fiber contents, can potentially eliminate the need for steel reinforcement in 3D printing without any need for manual placement of reinforcement. A set of systematic tests on ECC mix designs' fresh and …

The Influence Of Corrosion Mitigating Fluids On Post Tensioned Tendon Grout Properties And Steel To Grout Bond Strength, Sarita Ale Magar

USF Tampa Graduate Theses and Dissertations

Corrosion has been a persistent problem causing the failure of post-tensioned tendons in segmentally constructed bridges. To address this issue, the impregnation method has been considered where the corrosion-mitigating fluids are pressure injected into the interstitial spaces between the seven wires of steel strands. A previous study showed that this method was able to arrest corrosion. However, it compromised the bond strength between the steel and the strand. For that reason, this study aims to identify a fluid that can be impregnated into the interstitial spaces without sacrificing bond performance. The most promising fluid found in the study is an …

The Influence Of Bipolar Electrochemical Cell Geometry On The Studies Of Pitting Corrosion, Amin Kazem Ghamsari

In this study, commercially available connected vehicle data are used to develop crash prediction models for crashes at …

Modeling Vehicle-Miles Of Travel Accounting For Latent Heterogeneity, Fatemeh Nazari, Abolfazl (Kouros) Mohammadian

Civil Engineering Faculty Publications

Vehicle use is associated with negative externalities such as traffic congestion, air pollution, and greenhouse gas emissions. Particularly in the U.S. as a car-oriented country, vehicle use — in terms of vehicle-miles of travel (VMT) — has been on the rise and is projected to increase in the future. To curb the VMT growth and mitigate the associated externalities, policy makers can design informed strategies based on VMT predicted by vehicle use models. However, traditional vehicle use models capture merely the observed heterogeneity across vehicle decision making units (e.g., individuals) and ignore the latent or taste heterogeneity sourced in …
