A Shear Lag Anomaly
This technical note reports an interesting phenomenon associated with shear lag in the flanges of box girders that is quite contrary to well established ideas concerning this subject....

Floating Tire Breakwater Design Comparison
The design curves from two independent studies of the wave transmission and mooring force characteristics of Goodyear-type floating tire breakwaters are compared. The CERC wave transmission...

New Adjustment of North American Datum
The new adjustment of the North American Datum will be completed in 1984. The numerical problems associated with the simultaneous solution of 500,000 unknown parameters appear to be minimal....

Safety Studies Related to RRR Projects
The Federal Highway Administration has several research efforts specifically aimed at determining the impact of the Resurfacing, Restoration, and Rehabilitation (RRR) Program and, in general,...

Wind Tunnel Modeling of Building Internal Pressure
An inspectional analysis is made on the differential equations governing the fluctuations of the building internal pressure generated by wind for both single and multi-room buildings....

Citizen Participation in New York City Government
Following the example of London, England, New York City developed the first stage of Governmental decentralization in 1969 by forming 62 Community Planning Boards. In 1977, by Charter...

Earthquake Magnitude Scales
The use and meaning of earthquake magnitude scales are examined. Common misunderstandings regarding local magnitude, surface wave magnitude, and body-wave magnitude, are discussed and...

Uniform Flow over Skew Side-Weir
A rectangular channel with a skew side-weir is designed to obtain a uniform discharge distribution over the side-weir. Numerical and experimental results are presented. Geometric and flow...

The American Engineer Overseas
More and more American engineers will be working overseas, many for the first time. Frequently materials, laboratories and hardware equipment are not available and the engineer must first...

A Moral Appraisal of Cost-Benefit Analysis
A cost-benefit analysis is one in which the engineer weighs the possible positive consequences, or benefits, of a given action against the negative consequences, or costs, of that same...

Relationships Between Morphology of Small Streams and Sediment Yield
The state of the art in the relations between morphology of small streams and sediment yield is assessed. Research findings and recommendations for additional research are presented. Topics...

Compression of Free-Ends During Triaxial Testing
When lubricated platens (free-ends) are used to load particulate media there is an associated error in any measured axial deformation due to compression and distortion of the rubber/grease...

Conjoint Analysis of Residential Preferences
A methodology for studying the effect of different locational factors on individual residential preferences is developed. Observations on the overall preferences of individuals are used...

Random Shrinkage Stresses in Aging Viscoelastic Vessel
Shrinkage stresses caused by random variation of environmental humidity in a long cylindrical concrete wall sealed at the internal surface are analyzed, taking creep and aging of concrete...

Seismic Reliability of Lifeline Networks
An efficient method for seismic reliability assessment of lifeline networks, such as water distribution systems and communication or transportation networks, is developed. Lifeline component...

SPT Hammer Energy Measurement
A field measurement system and procedure which measures the energy delivered by a drill rig system was developed and successfully used to study the factors which affect delivered energy....

Optimal Design Based on Approximate Scaling
A new optimal design procedure, intended to reduce the number of exact analyses during the solution process, is proposed. High quality explicit approximations of the structural behaviour...

Exact Involute Bodies of Revolution
Involute construction is an approach used in contemporary rocket nozzle technology for the fabrication of exit cones and other bodies of revolution and consists of laminating identical...

Sediment Pollution Control in North Carolina
A review of state and local sediment control programs in North Carolina relative to urban and highway construction and sanitary landfill operations is presented. Law and institutional...

Steady Flow in Alluvial Channels
A theory is deveped to predict the formation and deformation of alluvial channels by relating the parameters of the transported substances (fluid and sediment) to those of the channel...
