Influence of silt size and content on static liquefaction potential of sand

Creator:: Monkul, M. Murat
Abstract:: Different specimen preparation methods such as moist tamping, dry funnel deposition, slurry deposition, dry air pluviation have been reported in the literature to investigate the undrained behavior of silty sands. Similarly, different means have been used to densify the soils prepared with such methods. However, the influence of the densification...

Behavioral thresholds in mixtures of sand and clay

Creator:: Simpson, Daniel Corder
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Right-hook crash causality at signalized intersections

Creator:: Jannat, Mafruhatul
Abstract:: A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...

Behavior of open grid steel bridge decks under service and fatigue loads

Creator:: Fetzer, Peter C.
Abstract:: Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

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...

Evaluation of ground motion duration effects on the damage prediction of building and bridge structural and soil-structural systems

Creator:: Belejo, Andre
Abstract:: The role of ground motion duration on the seismic performance of civil engineering structures remains unclear. Thus, the role of earthquake strong ground motion duration is assessed in a three manuscript thesis, which includes: (1) assessment of the effects of ground motion duration on the seismic performance of a model...

Shrinkage study of high performance concrete for bridge decks

Creator:: Fu, Tengfei
Abstract:: In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...

The Pozzolanic Reactivity Test and the Properties of Portland Limestone Cement

Creator:: Choudhary, Antara
Abstract:: The pozzolanic reactivity test (PRT) is used to quantify the pozzolanic reactivity of supplementary cementitious materials (SCMs). The PRT computes reactivity by measuring heat release (Q) and calcium hydroxide (CH) consumption, as interpreted using thermodynamic modeling. The robustness of PRT is examined by experimentally varying CH-to-SCM ratio, solution-to-solid ratio, sulfate...

Evaluation of Driver Behavior during Right Turn Maneuvers at Signalized Intersections: Mitigation of Driver-Pedestrian Conflicts with a Right Turn Flashing Yellow Arrow

Creator:: Jashami, Hisham
Abstract:: Accommodating motor vehicles that are turning (left or right) at signalized intersections requires a careful understanding of the safety and efficiency of design and operational variables. Turning vehicles are the primary collision risk for non-motorized road users at signalized intersections. When turning movements need to be controlled, proper driver response...

Enhancing Technology Integration in the Construction Industry : A Focus on Safety Technologies

Creator:: Nnaji, Chukwuma A.
Abstract:: Recent statistics suggest that the construction industry continues to experience poor project performance. Specifically, construction productivity has witnessed a meager annual growth of 1% over the past 20 years while the industry constantly records both a high number of fatalities and a high fatality rates relative to other industries. The...
