Site-specific load models and hazards for probability-based design

Creator:: Lee, Kyung Ho
Abstract:: Structural design codes have evolved continuously since modern codes were established. The allowable stress design format has been widely used since the late 191h century. During the past two decades, probability-based limit states design concepts have evolved and are increasingly being used for various material and structural types. Limit state...

Metal and organic emissions from RDF and large volume contributor combustion

Creator:: Lee, Taejin, 1961-
Abstract:: The use of municipal refuse (RDF) as fuels has received widespread attention for reason of its energy equivalence and the increasing lack of available landfill sites. The principal obstacle to the construction of combustion facilities is that RDF produces toxic compounds, including heavy metals and such organic compounds as PCDD...

Finite element analysis of wave-structure interactions in the time domain

Creator:: Lee, Jaw-fang
Abstract:: The time-domain simulation of wave-structure interactions using the finite element method is presented in this study. Combined initial and boundary value problems for diffraction and radiation of waves by large structures are posed. Linearized free surface boundary conditions are used, but motions of the structural boundaries compared to the wave...

Wave interaction with permeable structures

Creator:: Lee, Chung-pan
Abstract:: A theory is developed to provide an analytical solution to an unsteady flow field which is partially occupied by a porous structure. The flow is induced by a small amplitude incident wave train. The porous structure may contain multi-layer anisotropic but homogeneous media. Three typical porous structures are investigated: a...

Evaluation of desktop learning modules in civil engineering classrooms to promote inductive and interactive learning

Creator:: Buker, Kamilah E.
Abstract:: Students in undergraduate engineering programs typically do not synthesize content learned from disparate course work until the end of their final terms of college. As an example, in undergraduate civil engineering programs, transportation engineering concepts (e.g., geometric alignment, asphalt design procedures) and geotechnical engineering concepts (e.g., shear strength of soils,...

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...

Pedestrian safety at signalized intersections operating the flashing yellow arrow

Creator:: Tuss, Halston
Abstract:: At signalized intersections, pedestrians are considered to be amongst the most vulnerable. When in the crosswalk at intersections without protected left-turn phasing, pedestrians are particularly at risk from left-turning vehicles. Until recently, a wide variety of indications were in use across the US to indicate a permissive left-turn condition to...

Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

Creator:: Marnell, Patrick Stanley
Abstract:: Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues...

Pedestrian distraction : pedestrian behaviors at midblock crossings considering geometric and environmental conditions

Creator:: Kautz, Julia Anne
Abstract:: Pedestrian distraction at roadway crossings has been correlated with a higher risk of pedestrian-vehicle collisions due to the pedestrian's cognitive, visual, and motor attention being drawn to a wide variety of secondary tasks. This study is different from previous field studies of pedestrian midblock crossings in that the geometric layout...

Development of a Reliability-Based Framework and Empirical Models for Justifying Allowable Chloride Limits and Quantifying Critical Input Variables for Predicting the Service Life of Reinforced Concrete Structures

Creator:: Shakouri Hassanabadi, Mahmoud
Abstract:: Significant progress has been made over the past 20 years in developing models to estimate the service-life of reinforced concrete systems. The basic understandings of the mechanisms that control the transport of ions and moisture in concrete systems have been well researched and models for determining corrosion initiation, specifically chloride-induced...

Use of Flashing Lights in Traffic Safety of Vulnerable Road Users

Creator:: Ahmed, Ananna
Abstract:: Vulnerable road users, anyone interacting with the roadway facility without the protection of an automobile, experience greater risk for more severe crash outcomes. Multimodal roadway facilities often times provide less separation and more points of conflict between different types of road users. To promote vulnerable road user safety, transportation agencies...

A Review of Current State Department of Transportation Practice for Promoting and Documenting the Safety of Field Employees

Creator:: Barlow, Zachary Wesley
Abstract:: State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...

Integrating Driving Simulator Experiment Data with Multi-Agent Connected Automated Vehicle Simulation (Ma-Cavs) Platform to Quantify Improved Capacity

Creator:: Chand, Cadell Y.
Abstract:: Autonomous vehicles (AVs) at varying market penetrations will change traffic flow and highway performance. At AV market penetrations between 0% and 100%, human driven vehicles (HVs) will be interacting with AVs. However, little is known about how HVs interact with AVs. This study attempts to quantify HV headways when following...

Transportation Infrastructure to Support Bicycling in Dense Urban Environments : Design and Operational Considerations for Bicycle Lanes in Proximity to Commercial Vehicle Loading Zones

Creator:: Ghodrat Abadi, Masoud
Abstract:: While sophisticated plans have been adopted nationally and globally to increase bicycling’s share of daily commutes, safety concerns have negatively impacted targeted bicycling growth. Specifically, truck traffic plays a pivotal role in bicyclists’ perceptions of safety and comfort, because of the severe consequences of bicycle-truck collisions. Several types of engineering...

Modeling estuary pollution by computer simulation

Creator:: Grenney, William J.
Abstract:: A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

Sound and Vibration Analysis of Alternative Rumble Strips

Creator:: Horne, Dylan Ross
Abstract:: Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

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...
