Advancements in Aerodynamics, Fluid Mechanics and Hydraulics
The theme of these Proceedings is Advancements in Aerodynamics, Fluid Mechanics, and Hydraulics. As indicated by the title, the subject crosses disciplinary boundaries and deals with flow...
Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...
Three-Dimensional Boundary Element Techniques for Moving Boundary Problems
The boundary element method (BEM) is a powerful numerical method well suited for a wide variety of engineering problems. The numerical computations are performed only on the boundary of...
Hydrologic Simulation for Reservoir Development
Potential changes in the Manasquan River basin hydrologic budget were assessed with the Hydrological Simulation Program in Fortran (HSPF). The HSPF results were used to assess the reliability...
Microcomputers and Design Codes: A Case Study
A microcomputer analysis of the thermal stress problem in reinforced concrete box sections was conducted. An explicit finite difference algorithm for a one-dimensional heat flow analysis...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Improved Urban Traffic Flow Through Signal Re-timing?California Experience
The California Energy Commission (CEC) has initiated a new program to re-time all of the 20,000 interconnected traffic signals in the state, the first of its kind in the United States....
The Electronic Road Pricing System in Hong Kong
This paper addresses the traffic congestion problem and issues relating to the experiment of the world's first pilot scheme on Electronic Road Pricing System in Hong Kong....
Geotechnical Features of Fur Seal Island Design
In summer 1983, Texaco made plans to construct an artificial island in Harrison Bay of the Beaufort Sea to serve as a platform for exploratory drilling. Fur Seal Island is to be located...
Shear Strength in the Zone of Freezing in Saline Soils
The design of artificial islands and other geotechnical structures to support arctic offshore petroleum resource development requires considerable knowledge of the strength of frozen saline...
Failure Modes in Concrete Structures Due to Ice Load
Analytical methods are described for predicting local behavior of deepwater concrete structures subjected to short duration loading from floating ice. Overall analytical approaches such...
Undrained Cyclic Behaviour of Beaufort Sea Silt
Cyclic loading behaviour of Beaufort Sea silt has been studied under triaxial conditions, with and without static shear stress, to define the resistance to liquefaction or cyclic straining...
Arctic Oil Spills in Relationship to Sea Ice Motion
Sea ice on a scale of a few kilometers must be treated as a granular material rather than a continuum. The floes are in nearly constant motion relative to a fixed frame and each other....
Negatively Buoyant Flow in a Diverging Channel
Negatively buoyant (plunging) flow from a horizontal, constant width channel into a diverging channel has been studied in the laboratory. The study was undertaken to provide information...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
Proportional Weirs for Stormwater Pond Outlets
Many jurisdictions mandate that new developments must not cause runoff to flow downstream, during and after rainfalls, at rates higher than preconstruction. A common for controlling runoff...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Computer-Aided Studies of Complex Soil Moduli
Low-cost microcomputers and new electronic components make it possible to measure accurately the phase and amplitude of mechanical waves in the frequency domain at a small fraction of...
Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
