Effect of subduction zone earthquakes on SDOF bridge models

Creator:: Long, Yicheng
Abstract:: Current bridge design codes do not account for the effects of duration of mega-thrust subduction zone earthquakes. Furthermore, codes and even recent performance-based design methodologies only make use of the peak response quantities (forces, displacements, and ductility demands) and do not account for the increased number of inelastic cycles that...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

Multi-Criteria Risk Mapping Using Lean Tools for the Architecture, Engineering, and Construction Industry

Creator:: Viriato Maia Ferreira Pestana, Ana Catarina
Abstract:: Over the past two decades, the Lean Construction academic and practicing engineering community has used lean practices and tools to help improve the performance of the Architecture, Engineering, and Construction (AEC) industry. Lean practices have led to improved competitiveness of construction companies that have adopted them, by focusing on ways...

From Perception to Planning : Adaptation in Flood-risk Communities

Creator:: Gomez, Luis A.
Abstract:: This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...

Creator:: Claveria, Joseph B.
Abstract:: Distracted driving is an adverse driving behavior that is widely known to impair the safety of all roadway users and traffic flow. Despite the extensive research efforts on the prevalence and effects of distracted driving on roadway safety and performance, the number of vehicular crashes and fatalities resulting from distracted...

Modeling Unobserved Heterogeneity and the Injury Severities of Truck Drivers in Run-Off-Road (ROR) Crashes: Econometric Methods and Applications

Creator:: Al-Bdairi, Nabeel Saleem Saad
Abstract:: Recent statistics regarding large truck crashes reveal that fatality rates of large trucks per 100 million vehicle miles traveled (VMT) and fatality rates per 1,000 registered vehicles are higher than those for passenger vehicles. These statistics underscore the need for greater efforts by safety professionals to help mitigate the impacts...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Critical Assessment of Chloride States and Quantities in Ordinary Portland and Specialty Cements

Creator:: Ahmed, Ahmed Abdulhaq
Abstract:: The constituent materials of concrete often contain chlorides. The presence of chlorides in sufficient amounts can disrupt the passive layer, also known as the passive film, that protects the reinforcing steel in concrete. This disruption can lead to premature corrosion of the reinforcing steel in concrete. To minimize the risk...

Influence of Concrete and Construction Parameters on Chloride Test Measurements and Critical Chloride Threshold Limits

Creator:: Vaddey, Naga Pavan
Abstract:: The issue of chloride-induced corrosion of reinforcing steel in concrete and its economic impacts are well-known. Chlorides that cause reinforcement corrosion can be from constituent materials used to prepare concrete or can enter the hardened concrete when the structure is exposed to chloride environments. To minimize the risk of reinforcement...

The Number of Lanes and Crash Injury Severities of Commercial Motor Vehicle Drivers: Advanced Econometric Models and Applications

Creator:: Kim, Jaekook
Abstract:: Considering the deadly impacts of commercial motor vehicle (CMV) crashes on road safety, many previous studies have put in efforts to find the determinants of CMV crash injury severities. However, studies examining the impact of the different number of lanes on CMV crash injury severities are lacking. Besides, the importance...
