Improving Logistics Efficiency Through Collaborative Truck Routing, Patrick Dougherty 2021 University of Arkansas, Fayetteville

Improving Logistics Efficiency Through Collaborative Truck Routing, Patrick Dougherty

Industrial Engineering Undergraduate Honors Theses

The logistics industry is among the world’s largest and most essential. Specifically, trucking is a massive component of the modern logistics system. In 2012, truck transportation carried 68% of all freight tonnage in the U.S. However, trucking currently faces significant problems with efficiency and sustainability. Of all miles driven by trucks yearly in the U.S., 25% are driven with empty loads and 36% are driven with underutilized loads. In addition to this economic inefficiency, the industry faces social and environmental challenges. Driver turnover rates are near 100%, and trucking accounts for a significant level of greenhouse gas ...

Development Of Hybrid Ultra-High Performance Concrete Thermoplastic Composite Panels For Blast And Ballistic Protection, Alyssa M. Libby 2021 University of Maine

Development Of Hybrid Ultra-High Performance Concrete Thermoplastic Composite Panels For Blast And Ballistic Protection, Alyssa M. Libby

Electronic Theses and Dissertations

In recent years, ultra-high performance concrete (UHPC) has become a material of interest for structures needing resistance to impact and blast loadings. These types of loadings have induced brittle flexural failure in UHPC due to punching shear from the impactor. One way to improve the impact resistance, energy absorption, and ductility of UHPC is by adding fiber-reinforced polymer (FRP) skins to the front and rear faces of the concrete, resulting in a sandwich configuration. In this study, E-glass fiber-reinforced thermoplastic laminates were bonded to UHPC panels using a heated consolidation process known as stamp thermoforming. The bond between the UHPC ...

Burst Capacity Evaluation Of Corroded Pipelines Under Internal Pressure And Internal Pressure Combined With Longitudinal Compression, Shulong Zhang 2021 The University of Western Ontario

Burst Capacity Evaluation Of Corroded Pipelines Under Internal Pressure And Internal Pressure Combined With Longitudinal Compression, Shulong Zhang

Electronic Thesis and Dissertation Repository

Central to the design and integrity assessment of oil and gas transmission pipelines is to accurately evaluate their pressure containment capacities, i.e. burst capacities. Corrosion defects threaten the structural integrity of pipelines as they cause thinning of the pipe wall and therefore reduce the burst capacity. Corroded in-service pipelines may be subjected to longitudinal compression resulting from, for example, ground movement or formation of free spans, in addition to internal pressures. The main objective of the research reported in this thesis is to facilitate Fitness-For-Service (FFS) assessment of corroded pipelines.

The first study investigates the conservatism associated with the ...


Modeling Considerations For Built-Up Compression Members In Communication Towers, Ghada M. El-Mahdy P.Eng., CEng, Amro A. Alawamry 2021 The British University in Egypt

Modeling Considerations For Built-Up Compression Members In Communication Towers, Ghada M. El-Mahdy P.Eng., Ceng, Amro A. Alawamry

Civil Engineering

It is a well-established fact that built-up compression members exhibit extra flexibility than their equivalent solid members due to the shear action which effects the overall stability. This is usually taken into consideration by using a modified slenderness ratio for buckling modes that involve relative deformation of the interconnectors. Built-up members are often used as space truss members in communication towers. When modeling communication towers in structural analysis programs like SAP2000, the built-up member is usually defined as a single member element with a double section cross section. This does not catch the increase in deflection in the member due ...

Buckling Of Thin Cylindrical Shells: Imperfection Sensitivity, Non-Destructive Technique For Capacity Prediction And Application For Wind Turbine Towers, Kshitij Kumar Yadav 2021 University of Massachusetts Amherst

Buckling Of Thin Cylindrical Shells: Imperfection Sensitivity, Non-Destructive Technique For Capacity Prediction And Application For Wind Turbine Towers, Kshitij Kumar Yadav

Doctoral Dissertations

The presence of imperfections significantly reduces the load-carrying capacity of thin cylindrical shells and the reduction depends on the shape and the size of the imperfections. As a result, the prediction of the shells' buckling capacity requires a priori knowledge about the imperfections---a difficult, expansive, and time-consuming adventure, if not impossible. Consequently, thin cylindrical shells are designed conservatively using the knockdown factor approach that accommodates the uncertainties associated with the imperfections present in the cylinders; almost all the design codes follow this approach explicitly or implicitly. However, cylindrical shells can be designed more efficiently by making them insensitive to imperfections ...


Cold-Formed Steel Stud Assemblies Bearing On Concrete Slabs, Abbas Joorabchian 2021 University of Massachusetts Amherst

Cold-Formed Steel Stud Assemblies Bearing On Concrete Slabs, Abbas Joorabchian

Doctoral Dissertations

Cold-formed steel (CFS) bearing walls are frequently installed on concrete slabs, which do not provide perfectly rigid and uniform bearing conditions. Existing design guidance assumes bearing conditions have no impact on the axial capacity, though cold-formed steel compressive members are particularly susceptible to end conditions. Studs are typically installed at the edge of concrete slabs, which is prone to spalling and geometric irregularities. Moreover, they are occasionally installed inadvertently overhanging from concrete slabs. In this research project, the impact of non-uniform and partial bearing conditions on the axial strength of cold-formed steel wall assemblies is identified and characterized experimentally and ...

Artificial Intelligence Driven Infrastructure Management And Maintenance Plan, Julian Jesso

PhD Dissertations and Master's Theses

Rapid development in trucking technology and increasing demands in freight transportation has led to longer and heavier vehicles traveling on Florida’s highway system. Vehicles with gross vehicle weight (GVW) over 80,000 pounds, or permit vehicles, have significant effects on infrastructure, thus requiring an approved permit prior to departure. The combination of these increasing loads and harsh environmental conditions that Florida is subject to requires an enhanced infrastructure management program. Additionally, there is a need to eliminate inconsistencies in permit applications and derive a uniform maintenance practice for Florida’s infrastructure. In this research, the focus was to develop ...
