Modeling Human Error in Structural Design and Construction
Human error is recognized as the major cause of structural failure. Moreover, it may greatly exacerbate the damaging effect of other hazards, such as earthquakes. The objectives of this...
Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...
Shopping for a New Bridge Coat
Total shop coating of new steel bridges appears to be the best armor against corrosion. This alternative is one of three techniques for diminishing the difficulty and expense of painting...
Building on Water
During the last century, innovations in concrete have paved the way for the evolution of marine concrete structures. Oakland's proposed Carnation Container Terminal is using...
The Concrete Diagonal
Onterie Center in Chicago, Fazlur Kahn's last major structural design, is a companion in concrete to the diagonally braced steel John Hancock Center. It is a mixed-use building...
Designing for Shock Resistance
If a product or structure is subject to shock loadings, and is unable to take them without unacceptable damage, it must be insulated from the shock. The decision may be to redesign the...
Complexity in Concrete
Centrust Tower in Miami, Fla., is a $95 million, 37 story, 600,000 sq ft tower rising from one side of a block-square 11 story parking garage. Columns on the curved side of the triangular...
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....
Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
Quality of Inspectors?In Search of Excellence
Assuring quality in construction has become a major challenge to the design/construction industry today. Attention to the issue has been a result of problems in the nuclear power industry...
Management Lessons from Engineering Failures
Engineering failures are not always catastrophic. More are due to improper management of contracts rather than actual physical failures. Some result in loss of life; most result in disputes...
Bus Maintenance Cost Control
Effective bus maintenance programs are essential for the cost-effective provision of reliable transit service. Standard tools for maintenance management include preventative maintenance...
Wharf Stands on Stone Columns
A wharf was constructed in New Orleans on very weak soils. To prevent lateral and vertical movement of the soil, normally the entire wharf and adjacent structure would be founded on steel...
On-Line Computerized Maintenance Management
Maintenance is the last cost saving frontier of scientific management. Top management has concentrated on production for generations, largely ignoring maintenance. The attitude of 'fix...
Learning From Failure
Innovative engineering design involves assumptions about the future use and behavior of a structure. By understanding and learning from the infrequent but spectacular large failures, engineers...
Design of Strontia Springs Arch Dam
The development of the layout and the history of design of the 292 foot (89 m) high Strontia Springs Dam is presented. While a brief description of the general project layout and foundation...
Geology of the Strontia Springs Arch Dam
Precambrian metamorphic gneisses comprised the foundation rock at Strontia Springs Damsite. Geologic exploration at the axis selected for the arch dam revealed a large shear zone which...
The OCEANWHEEL Artificial Island
The compression rim and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
The Estimation of Ice Loads From Caisson Deformations Gulf Canada Molikpaq
The Gulf Canada Resources Mobile Arctic Caisson 'Molikpaq' is a bottom founded steel exploration platform capable of year-round operation in the Beaufort Sea....
Dynamic Global Forces on an Offshore Structure from Multi-Year Ice Floe Impacts
Estimation of global ice forces from ice floe impact against artificial islands and offshore platforms is essential for platform design. The discrete element program, CICE, has been validated...
