(2008-10-30)Department: Civil EngineeringThe present research aims to propose a new methodology for the failure analysis of heterogeneous thin plates. The problem is solved under the framework of hierarchial multiscale analysis. It is assumed that plates are ...
-
(2015-02-24)Department: Civil EngineeringFor effective bridge management, monitoring its health and repairing the detected damages efficiently are essential. The first part of this study uses acoustic emission (AE) technique for real-time health monitoring. For ...
-
(2016-11-11)Department: Civil EngineeringPotentially high risk medical procedures are performed in hospital operating rooms (ORs) across the country on a daily basis. There are detailed and stringent procedures in place for routine practices, such as handwashing ...
-
(2020-11-18)Department: Civil EngineeringCritical infrastructure systems provide essential services that support modern society. However, these systems are deteriorating and becoming more vulnerable to multiple hazards. In order to improve their resilience (i.e., ...
-
(2005-07-26)Department: Civil EngineeringSingle-plate connections, also called shear tabs, are an economical and efficient way to transfer load from one member to another, and are often found in steel-frame buildings. One type of shear tab is the extended shear ...
-
(2017-09-27)Department: Civil EngineeringThis dissertation investigates methods to implement big data analytics in structural health monitoring. Four types of activities are considered: (1) data processing; (2) structural damage diagnosis and prognosis with ...
-
Comparison of Interfacial Shear Strength measurements for Bonded materials and Composite materials (2008-09-23)Department: Civil EngineeringComposite materials play an important role in today’s engineering structures. These types of materials are made of two or more individual material components with weak interfaces in-between different material types. Since ...
-
(2006-06-27)Department: Civil EngineeringA reinforced concrete structure may degrade through a combination of coupled physical, chemical and mechanical deterioration processes. This study develops an integrated finite element-based computational framework to ...
-
(2015-03-20)Department: Civil EngineeringThis dissertation presents a multiphysics model to simulate and predict the deformation and failure of metallic materials and structures subjected to extreme loading and environmental conditions. The particular focus has ...
-
(2017-12-04)Department: Civil EngineeringDamage mechanics approaches are developed for the numerical modeling of fracture evolution along sharp (i.e., zero-thickness) and diffuse (i.e., finite-thickness) interfaces and applied to investigate ice sheet fracture ...
-
(2011-08-03)Department: Civil EngineeringMany of the steel and concrete bridges built in the 20th century are reaching the end of their planned service life in the early part of the new century. Corrosion and fatigue fracture of steel, and cracking, spalling, ...
-
(2020-03-18)Department: Civil EngineeringMotivated by the increased traffic and network capacity constraints of freight railroads in the United States, and the increased availability of operational data, this dissertation addresses the development of new methods ...
-
(2006-04-13)Department: Civil EngineeringThis study investigates day-to-day dynamics in an urban traffic network induced by internal and external factors under real-time information. A robust cost network optimization algorithm to account for the randomness of ...
