Deep-Water Platform Solutions for the Navarin Basin
The environmental conditions prevailing in the Navarin Basin may impose limitations on the type and shape of production, storage and loading structures. The magnitude of the wind and wave...
Foundation Response of Arctic Structures to Time-Dependent Ice Loadings
Arctic structures are subjected to a variety of time-dependent loadings, the most important of which are those due to ice. An approach is presented for estimating the strength and deformation...
Creep Rate Analysis of Pile Load Test Data
The uniform creep behavior of five driven piles and one slurried pile based on pile load test data are presented and analyzed. The incremental static load tests carried out by ARCO, Alaska...
Developing a Drilling Structure for Arctic Waters
Fluor-Doris of Houston has developed a mobile, composite concrete and steel drilling structure called the Arctic Composite Platform (ARCOP). This platform is capable of operations in water...
Arctic Drilling and Production Platform Concept
An 80-well Arctic drilling and production platform for water depths to 100 feet in the Beaufort Sea transition ice zone is presented. It includes a novel inner caisson to help resist large...
Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...
Earth Pressure on Underground Concrete Pipe in a Field Test
The cause of cracking at the sheetpile extraction in concrete pipes buried by the open excavation method was investigated by loading tests on the pipe and a field test carried out by Osaka...
Multi-Truss Design for Tower
A modified structural steel system of outrigger trusses and belt trusses bolster the 54-story Equitable Tower West. Located in New York City, the building's structural system...
The 1984 novel
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
Evaluation of Structures by Dynamic Load Testing
The Frequency Sweep Method for the evaluation of structures by dynamic load testing was developed by the senior author. It is a non-destructive testing (NDT) method that was originally...
Loads Due to Human Movements
The live loads due to human actions are random functions being modeled from data obtained from tests to determine load histories for the actions of individuals and small groups of people...
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...
Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Bridge Inspection by Dynamic Loading Technique
This paper describes, a case study of the evaluation of the structural integrity of a New York State Thruway bridge using the dynamic loading technique. The study was undertaken in a effort...
Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...
Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
Bentonitic Slurry in Constructing Drilled Piers
Bentonitic slurry is employed extensively in the construction of drilled shafts. While serious problems can occur, evidence is presented to show that the proper use of slurry will lead...
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
