Verification Of Lrfd Bridge Design And Analysis Software For Indot, Amit H. Varma, Jungil Seo
Verification Of Lrfd Bridge Design And Analysis Software For Indot, Amit H. Varma, Jungil Seo
JTRP Technical Reports
NCHRP Process 12-50 was implemented to evaluate and verify composite steel I-girder bridge design software used commonly in Indiana. A test-bed of twenty one bridges was developed with the guidance from an Indiana Department of Transportation appointed research advisory panel (RAP). The test-bed included five simple-span and sixteen multi-span bridge superstructures. More than 80 parameters were required to define a bridge and they include bridge span, girder spacing, number of beams, section type, steel strength, girder sections, and other required bridge parameters. Some of these parameters were initially selected by INDOT and practitioners.
An indigenous computer program PURDUE CSBD was …
Mechanistic-Empirical Modeling In Network-Level Pavement Management, Scott Schram, Magdy Abdelrahman
Mechanistic-Empirical Modeling In Network-Level Pavement Management, Scott Schram, Magdy Abdelrahman
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Researchers and practitioners have long recognized the advantages of mechanistic modeling. As agencies implement the Guide for Mechanistic-Empirical Design of New and Rehabilitated Pavement Structures [referred to as the Mechanistic-Empirical Pavement Design Guide (MEPDG)] in the local project-level pavement management system (PMS), its potential as a planning tool in network-level analyses remains unrecognized. A unique, large-scale application of MEPDG is presented. The Nebraska Department of Roads uses a decision tree that systematically screens and identifies candidates for entry into a multiyear optimization program. The process uses linear deterioration rates that have been shown to provide an R2 value as …
Systems Approach For Estimating Field Moisture Content, Thomas M. Petry, Yuh-Puu Han, David Newton Richardson
Systems Approach For Estimating Field Moisture Content, Thomas M. Petry, Yuh-Puu Han, David Newton Richardson
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
This paper describes a software tool developed for estimation of the field moisture content of subgrade materials. Subgrade behavior is directly related to its moisture content. Unfortunately, some approaches of estimating field moisture content are too complex to be used in routine design. In this paper, the authors attempt to provide an approach that is easy to use. The software presented here was developed using expert system approaches. It is capable of analyzing data entered by the users, and providing estimations to meet different scenarios. The information entered by the user is first examined for its reasonableness and accuracy. Then, …
Sensors To Monitor Cfrp/Concrete Bond In Beams Using Electrochemical Impedance Spectroscopy, Sangdo Hong, Ronald S. Harichandran
Sensors To Monitor Cfrp/Concrete Bond In Beams Using Electrochemical Impedance Spectroscopy, Sangdo Hong, Ronald S. Harichandran
Civil Engineering Faculty Publications
The use of inexpensive electrochemical impedance spectroscopy based sensor technology for nondestructive evaluation (NDE) of bond degradation between external carbon fiber-reinforced polymer (CFRP) reinforcement and concrete is examined. Copper tape on the surface of the CFRP sheet, stainless steel wire embedded in the concrete, and reinforcing bars were used as the sensing elements. Laboratory experiments were designed to test the capability of the sensors to detect the debonding of the CFRP from the concrete and to study the effect of short-term (humidity and temperature fluctuations) and long-term (freeze-thaw and wet-dry exposure and rebar corrosion) environmental conditions on the measurements. The …
Right Turn Split: A New Design To Alleviate Weaving On Arterial Streets, Khaled Shaaban
Right Turn Split: A New Design To Alleviate Weaving On Arterial Streets, Khaled Shaaban
Electronic Theses and Dissertations
While weaving maneuvers occur on every type of roadway, most studies have focused on freeway maneuvers. Weaving occurring on non-freeway facilities, such as arterial streets, can cause significant operational problems. Arterial streets weaving typically occur when vehicles coming from a side street at an upstream intersection attempt to enter the main street from one side to reach access points on the opposite site at a downstream intersection by crossing one or more lanes. This dissertation investigates the type of problems occurring on arterial streets due to the weaving movements and recommends a new design to alleviate weaving on arterial streets. …

Evaluation Of Indot Hyperfix Project, Kumares C. Sinha, Bob G. Mccullouch, Darcy M. Bullock, Sravanthi Konduri, Jon D. Fricker, Samuel Labi
JTRP Technical Reports
In 2003 the Indiana Department of Transportation executed an ambitious interstate reconstruction project in Indianapolis, named Hyperfix. This project completely closed the I-65/70 section during reconstruction, on which approximately 250,000 vehicles travel daily. Due to the scope and risk involved, an extensive amount of planning, coordination, and cooperation occurred. The main section was rebuilt during the total closure phase, which lasted 55 days. The total closure approach had never been performed before by INDOT on such a high volume artery in a downtown metropolitan area. This present study analyzed the project and its impact on the Indianapolis area. The report …
Shear Strengthening Of Rc Beams Using Carbon Fiber Reinforced Polymer Laminates, Zhichao Zhang
Shear Strengthening Of Rc Beams Using Carbon Fiber Reinforced Polymer Laminates, Zhichao Zhang
Dissertations
Shear failure is catastrophic and occurs usually without advanced warning, thus it is desirable that the beam fails in flexure rather than in shear. Many existing reinforced concrete (RC) members are found to be deficient in shear strength and need to be repaired. Deficiencies occur due to several reasons such as insufficient shear reinforcement or reduction in steel area due to corrosion, increased service load, and construction defects. Externally bonded reinforcement such as Carbon Fiber Reinforced Polymer (CFRP) provides an excellent solution in these situations.
In order to investigate the shear behavior of RC beams with externally bonded CFRP shear …
Design Criteria For Usu Stilling Basin Pipe Flow To Open Channels, Chi-Yuan Wei
Design Criteria For Usu Stilling Basin Pipe Flow To Open Channels, Chi-Yuan Wei
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Criterion have been developed in this study for designing a stilling basin to serve as a transition from pipe flow to open channel flow. The purpose of the structure is to prevent erosion in an open channel. The unsteadiness, or smoothness, of the water surface in the model basin was used as the criterion for evaluating the effectiveness of the structure for energy dissipation.
The introduction of a short-pipe energy dissipater in the stilling basin has proven effective in dissipating energy. The stilling basin was designed for a fully submerged pipe outlet. The inflow pipe and the dissipator pipe were …
