Reduction of Seismic Response in Breeder Plants
Thin-walled vessels to be used in the Nuclear Steam Supply Systems (NSSS) of future LMFBR's will be more sensitive to seismic excitation than their equivalents used in conventional...
Testing for Salt Damage
Salts used to melt snow can contribute to deterioration of concrete structures. Various tests were used to determine the extent of damage in two structures in Rochester, N.Y. One is an...
In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...
Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Aquaculture in Dredged Material Containment Areas
The beneficial use of active dredged material containment areas through aquaculture appears to offer, under certain circumstances, benefits to the Federal government, municipal and industrial...
Reduction of Intake Flow Due to Ice Rubbling and Consolidation
Numerous seawater intakes have been designed for Arctic Coastal Waters. In these areas moving ice often causes rubbling and pile up of broken ice pieces against the shore. If this forms...
Retaining Walls: Competition or Anarchy?
Until the last 10 years, when a retaining wall was needed a cast-in-place concrete gravity or cantilever wall was used. Then along came Reinforced Earth, and this proprietary system began...
Afloat on the China Sea
In the summer of 1982, the Science and Technology Commission of the People's Republic of China invited four United States tunnel experts to come to China to engage in technical...
Holland's Fight Against the Sea
The Netherlands have always been threatened by the sea, its Delta Region most of all. After the catastrophic floods of 1953, the Delta Plan for the strengthening of coastal defenses and...
Lightweight Fill Helps Albany Port Expand
Lightweight aggregate was used as a soil fill in the reclamation of a marine terminal at the Port of Albany, New York in order to stabilize the dockside area. Gravel-filled steel sheet...
A New Panama Canal?
The Panama Canal is expected to be obsolete by the end of the century. Already there are serious problems with ship traffic through the Canal: volume of traffic is down, average transit...
Coastal Zone '83
Interdisciplinary information and viewpoints on coastal zone management and ocean resources issues related to use, protection, and development are presented. Topics include improved jurisdiction...
EPCOT
EPCOT Center, perhaps the most elaborate and futuristic entertainment attraction in the world, is also a major achievement in such civil engineering-related disciplines as geotechnical,...
Restoration
After the San Fernando earthquake of 1971, California's State Capitol Building was declared an earthquake hazard and vacated. It took the most extensive structural and architectural...
Artificial Islands
Artificial islands constructed from gravel fill have become a preferred approach to drilling for oil in hostile Arctic environments. These man-made islands are being built to serve as...
Characterization of Offshore and Coastal Ice Conditions
Seasonal sea ice conditions typical of nearshore coastal zones are reviewed. Prominent ice features influencing design ice conditions for offshore structures are described. This paper...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
In Search of Ancient Engineers
Many examples of pre-Columbian civil works have been uncovered in North and South America. Some reflect well-organized technologies comparable to those of the Old World of the same time...
Rehabbing Historic Buildings
Historic buildings often require structural upgrading before the cosmetics of restoration can be applied. Two case studies are presented here. The Four Seasons Hotel in Seattle required...
