Application and Recent Development of a Numerical Model for Composite Beams with Partial Shear Connection
This paper deals with numeric analysis of composite steel and concrete beams for loads up to the ultimate beam capacity. Two versions of a numerical model are presented addressing such...
ICAO's ACN-PCN Method and Aircraft-Pavement Interaction
Multi-wheel gear assemblies of future aircraft are not compatible with pavements rated in the ACN-PCN system given by the International Civil Aviation Organization (ICAO). The Aircraft...
Evaluation of Elastic Layered Theory for Airfield Pavements, Using Nondestructive Testing and In-Place Response Measurements
Airfield pavement deflections measured under actual aircraft loads were compared to predictions based upon elastic layer theory and moduli backcalculated from failing weight deflectometer...
Execution and Evaluation of High Capacity Caisson Load Tests in Glacial Deposits
As part of the Boston Harbor clean up project, the new 1,000 mgd Deer Island Sewerage treatment plant includes ten 240 feet high egg-shaped 'residuals' tanks. Contract documents called...
Bi-Directional Load Testing of Shafts to 6000 Tons
This paper describes the use of Osterberg cells (O-cells) to perform bi-directional load testing on full size production drilled shafts for a major bridge foundation near Owensboro, Kentucky....
Tying Up The Artery
After six years, preliminary design is almost complete on one of the nation's largest, and most complicated, public works project, the Boston Central Artery project. At an...
Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...
Fine Tuning the Airfield: The New Denver International Airport
This paper discusses airfield layout considerations that have been incorporated into the design of the new Denver International Airport (DIA). These concepts include some unique provisions...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
Comparison of Delay and ICU Analyses?Case Study
Traffic Management Initiative was a petition-based referendum that sought to limit traffic impacts of proposed or planned development through the use of more stringent transportation planning...
ICU?A Method of Analyzing Signalized Intersections
There is a need for decision makers, developers and the public to understand the potential traffic impacts of site development. Signalized intersection operations are a primary indicator...
Access Management ? Myth or Reality
The concept of access management has emerged over the past decade as a means of preserving the functional integrity of the arterial road system while simultaneously providing access to...
Shouldn't it be
A Traffic Impact Assessment is a single mode analytical tool that is used to evaluate new development proposals. Its use continues at a time when the transportation community is being...
Traffic Impact Studies for Marriott Corporation International Headquarters
This paper describes the steps taken in developing innovative traffic-related solutions to obtain approval for the Marriott Corporation International Headquarters site, which is planned...
Defining Traffic Impacts of Redevelopment
Developers have proposed to replace the existing, defunct Old Mill Specialty Retail Center with a primarily residential project. The balance of the Old Mill site will consist of smaller...
Are Existing Traffic Methodologies Realistic?
Several issues that will need to be addressed in the development of national uniform guidelines for Traffic Impact Statements (TIS) are discussed. A standard TIS preparation methodology...
Calibration of Redundancy Factors for Highway Bridges
The object of this study is to develop a framework for considering redundancy in design and load capacity evaluation of highway bridge superstructures. The proposed method consists of...
Probabilistic Evaluation of Bearing Capacity of Shallow Foundations
A probabilistic model is developed to evaluate the bearing capacity of shallow foundations. The bearing capacity formulation proposed by Terzaghi is used but with the bearing capacity...
Bridge Overloading Criteria
Considerable concern is being expressed by the public and government agencies over the deteriorating state of the country's infrastructure. At the same time, there is a general feedling...
Experimental Investigation of Self-Tapping Fasteners for Attachment of Corrugated Cladding Panels to Pultruded Fiber-Reinforced Plastics Beams in Industrial Building Construction
This paper describes an experimental investigation of self-tapping fasteners for the attachment of corrugated fiber-reinforced plastics (FRP) cladding panels to pultruded FRP beams. Although...
