Computer Assisted Design and Construction
This paper presents a comprehensive package for conducting structural analysis, design, and project management on microcomputers. Several examples are presented to illustrate the usefulness...
The Virtual Design Team: An Object-Oriented Model of Information Sharing in Project Design Teams
The Virtual Design Team (VDT) is an object-oriented, discrete event simulation of a multidisciplinary design team in action. The VDT models a design task as a network of design and design...
Site Layout: Where Should it Go?
Site layout is mostly treated as a task independent of other resource allocation tasks such as those that are traditionally associated with construction planning and scheduling. Yet, the...
Ductile Frames Are Tough for Earthquakes
Implications of a new structural system in wharf design go far beyond San Francisco Bay, where two such wharves remained intact after the 1989 Loma Prieta quake. The design, introduced...
Methane Tracer Technique for Gas Transfer at Hydraulic Structures
Using a simple headspace gas chromatographic technique, gas transfer at several hydraulic structures were investigated. Naturally occurring methane was used as a tracer gas to measure...
Gas Transfer at Hydraulic Structures
The objective of this paper is to identify and briefly summarize the state-of-the-art in measuring and describing gas transfer at hydraulic structures. Basic theory of mass transfer at...
Oxygen Transfer at Spillways
A relationship for oxygen transfer efficiency, E, at spillways and gated spillways with a hydraulic jump or plunge pool, has been developed from conceptual considerations and fit to measurements...

Rehab Roundup
The concrete exterior of San Franciso's Coit Tower was damaged and the murals were being destroyed by water infiltrating the structure. Interactive Resources, Inc., Point...
Quake-Safe Housing, Again
Because so little data exist about earthquake behavior of buildings that have been strengthened to meet seismic codes, many engineers are curious about the Hotel Oakland in California...
Corrosion Below: Sewer Structures
When a sewer system fails, the cause is often not the pipe but a manhole, junction or other special-purpose structure. Most of these structures are concrete, either cast in place or precast....
Special Bedrock Conditions in Greater Boston
The Cambridge Argillite, a weakly metamorphosed shale, forms the major portion of the Boston Basin, a structural as well as topographic depression. In the greater Boston area, the argillite...
Foundation Studies in a Fault Zone and a Steep Valley Slope
This paper presents two case histories which illustrate unique problems in defining the character of rock for support of structures. The first case study concerns a conventional building...
Soil-Rock Transition Zone: Uncertainties for Design and Construction
This paper addresses the problem of establishing definitions of the soil-rock boundary with regard to different engineering applications in the Piedmont geologic provinces. Three engineering...
Ground Stabilization in Shallow Depth Soft Ground Tunneling
A new approach was employed for ground stabilization to drive a semi-circular cross-section tunnel with overall dimensions of 24 ft (7.3m) wide, 12 ft (3.7m) high, and 164 ft (50.0m) long....
Rock in the Limestone Regions of the Southeastern United States
Problems often arise in the shaft drilling industry in the Southeast. The karst areas in this region have certain situations found in few other places. Erratic boulders and limestone pinnacles...
Ultimate Air Rights
The new 1 million sq ft office tower at 450 Lexington Ave. rises from available space between commuter railroad tracks, through the center of a renovated four-story post office and up...
Floating Fabric Over Georgia Dome
The 400,000 sq ft free-span roof cover the new $210 million Georgia Dome may look as festive as a circus tent. But next fall, when the 70,500-seat arena becomes the home of the Atlanta...
Flawed Assumptions: Why Bridge Deck Joints Fail
Engineers should continually examine, evaluate and improve their representations of reality to avoid basing their beliefs, decisions, practices and policies on flawed assumptions. Such...
