Structural Condition Assessment Of Prestressed Concrete Transit Guideways
Objective condition assessment is essential to make better decisions for safety and serviceability of existing civil infrastructure systems. This study explores the condition of an existing transit guideway system that has been in service for thirty-five years. The structural system is composed of …

Development of structural condition thresholds for TSD measurements
… deflection thresholds to classify the pavement structural condition obtained from the TSD for a small subset of the Pennsylvania secondary road network. The results of the field evaluation included: (1) repeatability of the TSD, (2) ability of the TSD to identify pavement sections with varying …

Network-Level Structural Condition Data for Sustainable Pavement Asset Management
… PMS frameworks rely primarily on surface condition indicators such as cracking, rutting, and roughness to trigger treatments and allocate resources. While surface condition measures provide valuable insight into the functional performance of pavements, they do not directly capture the …

Some Assembly Required: The Structural Condition of Collage in Architecture and Urbanism
… intention through this thesis to investigate the structural condition of collage as a culturally relevant approach to understanding architectural meaning and designing architectural form within the context of the urban environment. Meaning in architecture, as it emerges both implicitly and …

Structural Condition Assessment and Service Load Performance of Deteriorated Prestressed Concrete Deck Beam Bridges
The critical signs to be observed in existing structures that will lead the inspectors to conclude that a deck beam is being overloaded were are also studied. Several conclusions were found. Cracking of the longitudinal joint has little effect on the stiffness of the bridge if the transverse rod is …

Network Level Decision-Making Using Pavement Structural Condition Information From The Traffic Speed Deflectometer
Pavement structural condition plays a critical role in the rate of pavement deterioration, yet most state highway agencies' network-level decision-making processes are primarily based on surface distresses. Despite the limitations of the traditional structural condition measuring devices, some …

Study of Condition Monitoring of Bridges Using Genetic Algorithms
A new methodology is developed to monitor the structural condition through non-destructive evaluation techniques using genetic algorithms. System identification techniques are used to establish the mathematical model of the real structural system through parametric methods. The problem of …

Condition Monitoring of Structures by Using Ambient Dynamic Responses
The thesis presents the general procedure for structural condition monitoring of civil structures by using ambient dynamic responses. The proposed monitoring system is composed of three components: the data acquisition system, the damage identification algorithm, and the damage verification …

Preservation of early wrought iron trusses : the 1848 roof of the Cochituate gatehouse
… thesis investigates the historic significance, structural condition, and preservation challenges of the wrought iron roof trusses of the Cochituate aqueduct's inlet gatehouse as the possible earliest surviving example of their type in the United States. Through an examination of the existing …

A Pavement Structural Capacity Index for Use in Network-level Evaluation of Asphalt Pavements
The objective of this research was to develop a structural index for use in network-level pavement evaluation, which facilitates the inclusion of the pavements structural condition in many pavement management applications. The primary goal of network-level pavement management is to maintain an …

Developing Condition-Based Triggers for Bridge Deck Maintenance and Rehabilitation Treatments
… system suffer from deficiencies in both their structural condition and functionality. In an effort to improve the condition of bridges, highway agencies continually seek effective and efficient approaches to maintenance and rehabilitation (M&R) treatments for their bridges. However, one …

Alternatives to PCI and MicroPAVER based maintenance solutions for airport pavements
… need to be maintained for adequate health condition by implementing cost effective maintenance solutions. Traditionally, maintenance and repair techniques have been developed based on the minimum acceptable Pavement Condition Index (PCI). However, there are pavements which show high PCI but …

Air-coupled non-destructive evaluation technology for condition assessment of railroad ties
… non-destructive evaluation (NDE) technology for condition assessment of railroad ties. Ultrasonic surface waves are generated in railroad ties using an air-coupled ultrasonic sender. Surface waves are sensed at the receiving end using an array of Micro-Electro Mechanical sensors (MEMs). The …

The Rhetoric of Gallows Humor: The Settler Colonial Unconscious in Reservation Dogs
… how Reservation Dogs uses humor to expose these conditions while fostering survivance, refusal, and community. Chapter one situates Native comedy historically as a form of gallows humor emerging from conditions of marginalization. Chapter two analyzes the Tall Man trope and representations of …

Visual inspection and bridge management
… method for bridge structures, whereby a condition rating is assigned reflecting the structural condition of a bridge, based on the judgements of a trained inspector. The impact of data collected from visual inspection is contingent on its ability to guide towards optimal maintenance …

IL CANONE DELLA RIDUCIBILITÀ ALLA PROVA DEI FATTI: CRITICITÀ PERSISTENTI NEL MECCANISMO DI LEGITTIMAZIONE DELLA PENA PERPETUA
… particular on the principle of reducibility as a structural condition for the legitimacy of life sentences. Starting from an analysis of the normative framework and the constitutional foundations of punishment, the work traces the emergence of reducibility as an essential criterion to prevent life …

The over-indebtedness of public servants in South Africa
… concept of over-indebtedness is described, as a structural condition of a consumer that experiences financial is unable to repay credit commitments. This paper briefly describes the evolution of consumer credit and discusses the causes and consequences of overindebtedness. The study evaluates the …

Development of Enhanced Pavement Deterioration Curves
… only a few models exist that incorporate the structural capacity of the pavements into deterioration modeling. This thesis develops pavement deterioration models that take into account, along with the age of the pavement, the pavement structural condition expressed in terms of the Modified …
