Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
Reconstruction Under Traffic: A Study of Some Effects of the Dan Ryan Project on Motor Carrier Operations in Northeast Illinois
The paper discusses preparations by the Chicago Area Transportation Study for a study of the operational responses of truckers to whatever effects upon the regional highway system are...
The Truck Commodity Survey in the New York-New Jersey Metropolitan Area
The Truck Commodity Survey was designed to gather information on the characteristics of truck traffic at toll barriers with minimal disruption to traffic flows. It was developed by the...
Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...
Engineering Design Concerns Regarding Steel Fabrication
The precise fabrication of structural steel pieces is an essential part of the process leading to the satisfactory erection and connection of the individual steel elements into the final...
Effective Length Factors for Type-PR Frame Members
The effects of PR-Type connections and loading arrangement on frame stability and the effective length factor of columns are evaluated for portal frames and three-story three-bay frames...
Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...
The Design of Diagonal Cross-Bracing
The results of an analytical and experimental study on the behavior of simple and double diagonal cross-bracings in vertical stiffening trusses and in built-up open web beams are presented...
Unistrut Space Frame Systems and Their Application
A review of the application of latticed structures is presented. The design and construction of space frames is dependent upon the availability of adequate connection systems to realize...
Optimized Wall Thickness of Shells of Revolution
The aim of this paper was to develop a concept for the design of shells of revolution with different Gaussian curvature using a simplified finite element buckling analysis. A cooling tower...
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Fatigue and Fracture Evaluation of Riveted Bridge Members
Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...
Equilibrium-Serviceability Design of Hyperstatic P. C. Beams
A practical flexural design procedure for continuous prestressed concrete girders based on simulataneously ensuring specified margins of safety against both limit states of section and...
Issues in the Validation of Probabilistic Methods
Probabilistic models are being used increasingly in safety assessments and regulatory decision-making. There is a need to relate the risks computed using these models to service data in...
Applications of Probability for Structural Analysis in the Nuclear Industry
Probabilistic techniques are being used as part of structural analysis in the nuclear industry to investigate various safety-related issues. Historically nuclear power plants have been...
Design and Construction of A 1/6 Scale, LWR Reinforced Concrete Containment
This paper summarizes the closely coordinated engineering and construction planning associated with the design and construction of a reinforced concrete containment model. Designed at...
Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...
