Fatigue Strength of Welded Wire Fabric
Long life fatigue tests were made on 12 concrete slabs reinforced with large diameter, Grade 75, deformed welded wire fabric. The specimens simulated, to full scale, conditions in a bare...

Axial Fatigue Model for Wire Rope Strand
A numerical fatigue model for cables and rope strand subjected to fluctuating axial tension has been developed. This model determines the maximum wire nominal and Hertz contact stresses,...

Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...

Microcomputer Applications for Pavements
The Federal Highway Administration (FHWA) has been active in exploring expanded microcomputer applications with the goal of improving efficiency and benefits to the public through reducing...

Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
A preliminary design and construction plan for a prototype wave energy conversion system is described. While the design methodology and construction procedures are intended for generic...

Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...

Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....

Structural Design of Container Cranes
The shipping industry uses container cranes to move cargo containers on and off ships. Container cranes have characteristics common to all crane structures, but many characteristics are...

Life Cycle Analysis
Of all the infrastructure elements, pavement performance has probably received more research than any. Similarly, there has been more application of pavement research. The concepts that...

Infrastructure Project Management and the Power of Implementation
The purpose of this paper is to bring renewed attention to project management concepts and public policy implementation issues as they apply to infrastructure development and renewal....

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

Survival of Ocean Life: The Critical Balance
Several major problem areas in ocean management are in need of immediate and stringent address. Excessive erosion and sedimentation, stems from man's inadequacies in land...

Structural Integrity Assessment of the Flexible 870 Advanced Design Bus
The Grumman Flxible 870, a lightweight advanced design urban bus, entered service in Atlanta, GA in 1978, and some 2,800 of these buses were in service nationwide by 1980. In the autumn...

Damage Tolerance Assessment of Commercial Airframes
The regulatory authorities now require that commercial transport aircraft structural design be based on a damage tolerance philosophy. A brief history of the development of the regulations...

What Do Pavements Cost?
Life-cycle costing is a rational tool used to forestall problems with highway infrastructure. Currently this tool is still an imprecise one. The Federal Highway Administration has a system...

Managing by Database
Many computer programs are available for managing the operations and maintenance aspects of a facility. To date, most computer programs for managing a facility have been generated by mechanical...

Behavior of Metal Structures
This technical symposium illustrates the various aspects of transfer of information from research results to engineering practice. The papers cover historical technical background, current...

What Type of Sewer Pipe is Best? Life-cycle Cost Analysis Yields Answer
In the past, many engineers have selected the type of sewer pipe for a particular project based mainly on a comparison of initial costs of concrete, steel, and other types of pipes. This...

Selected Papers by Alfred M. Freudenthal
Civil Engineering Classics
Fifty-six papers written by Alfred M. Freudenthal, or co-authored by Prof. Freudenthal, are included. The papers are divided into three areas: structures, theories of mechanical behavior...

Fatigue Cracking�Problem for Welded Steel Bridges
A recent problem with welded steel bridges is fatigue cracking at welded details. Fatigue cracks begin in small flaws or discontinuities at welded connections and grow to a critical size...
