Interactive Bridge Optimization Program
This paper presents the development of a design methodology that includes the structural optimization process as an integrated component of girder bridge design. The optimization process...
Techniques for Rapid Assessment of Seismic Vulnerability
Under the impetus of a growing awareness of seismic hazards, there is an increasing effort being devoted to assessing the seismic vulnerability of existing buildings. For many professionals...
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,...
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...
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...
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...
Electrical Resistivity Techniques for Offshore Arctic Geotechnical Engineering Applications
The electrical resistivity of an arctic marine soil depends on the porosity, pore water salinity, grain size and shape, clay content, and degree of ice-bonding of the soil. Therefore,...
The Role of Ice Gouging in Determining Global Forces on Arctic Structures
Structures built in water depths where ice keels are in contact with the seafloor can experience reductions in the environmental driving forces transmitted to structures due to seafloor...
Utilizing Design Events Within Risk-Based Design
Design load selection based on the return period of an environmental event is not possible when the event is described by more than one parameter. Risk analysis can be used to associate...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
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....
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...
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Probability-Based Load Criteria for Structural Design
Load criteria for use in limit states design of structures are developed using probabilistic methods. Statistical data on load and strengths are integrated by the reliability analysis...
Design Load Combination Factors
This paper reviews alternative load combination formats for ultimate limit states in codified structural design. The need for explicit consideration of load-time variations and random...
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...
