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...
Rapid Identification of High Risk Building in Seismic Regions Using Expert Systems
Seismic risk evaluation is a complex problem because it involves many factors such as ground motion, ground failure potential and structural performance with great uncertainties. Many...
Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...
Knowledge-Based Consultant for Construction Inspection
This paper shows how knowledge-based expert systems can be implemented in construction inspection to provide the necessary information needed by an inexperienced inspector to inspect complex...
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...
Knowledge Bases for Multistory Concrete Buildings
Heuristics are used in the concrete building industry. A knowledge base is developed with heuristics used in the selection of the floor framing system of a concrete building....
A Knowledge Based Technique for Structural Component Design Programs
Traditionally, computer programs written for the purpose of sizing and checking standards compliance of individual structural members have been authored in high level compiled languages...
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...
Designing People Places
Designing people places on the waterfront relies on first satisfying people's needs. The needs of people in public places (both on and off the waterfront) include at least...
The Changing Configuration of Commercial Ports
The ports of the world are constantly changing. The present day concept of a ship or barge entering a harbor, being unloaded, reloaded and 'sailing' out is not...
Urban Runoff Impacts on Receiving Waters
Urban stormwater runoff contaminants affect the principal receiving water uses of: (1) public water supply, (2) recreation, (3) protection of aquatic life forms, (4) agricultural and industrial...
Isolating Earthquakes
The Foothills Communities Law and Justice Center in Rancho Cucamonga, Calif., is the first U.S. building to rest on base isolators for protection against a possible earthquake of 8.3 Richter....
Facility Location and Land Use
The Urban/Rural Dilemma
Most land use planning techniques focus on large metropolitan areas, with relatively little attention paid to smaller communities. Recent issues such as nuclear power plant location, water...
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....
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...
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...
