Design Mentoring Tool, Bob Mccullouch, Walter Land

JTRP Technical Reports

In 2004 a design engineer on-line mentoring tool was developed and implemented The purpose of the tool was to assist senior engineers mentoring new engineers to the INDOT design process and improve their technical competency. This approach saves senior engineers time while developing a consistent mentoring approach and standardizing technical knowledge in road and bridge design. It is a self-guided tool that utilizes multi-media and web-based technologies, trains engineers in the design process and provides resources to use for developing plans and specifications. Available resources include INDOT design practices, design standards, design memos, specification and construction standards, procedures, and check …

Design And Applications Of Drilled Displacement (Screw) Piles, Prasenjit Basu, Monica Prezzi

JTRP Technical Reports

Drilled displacement (DD) piles (commonly known as „screw piles‟ in Europe) are being increasingly used as foundation elements for structures, particularly in projects requiring accelerated construction or involving the rehabilitation of foundations of existing, overstressed structures. Different types of DD piles are available in practice; each type is classified according to the design of the drilling tool and associated installation method. Installation of DD piles causes substantial changes in the state of the soil surrounding the pile. These changes result from the complex loading imposed on the soil by expansion of a cylindrical cavity to make room for the specially …

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 …

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 …
