Fracture Theory for Nonhomogeneous Brittle Materials with Application to Ice
Brittle heterogeneous materials generally fracture with a dispersed zone of microcracking at the fracture front. The deformation and failure of these materials can be described by a nonlocal...
Validation of the CICE Code for Ice Ride-Up and Ice Ridge Cone Interaction
The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves...
Stochastic Finite Element Analysis of Gravity Platform Foundation
Gravity foundation design requires determination of total and differential settlement, vertical stress distribution beneath the raft and maximum shear stresses in the sand layers in the...
A Hybrid Structural Ice Defense Mechanism
A hybrid plate composed of steel outer surfaces and a concrete core has characteristics that make it desirable for use on offshore structures in ice prone environments. The service and...
Jumbo Modules for Artificial Islands
The development of the Arctic Offshore oil fields has led to the consideration of gravel islands or other structures to support oil production facilities. The island and the assembly site...
Ice Forces on Port Structures Resulting from Moving Ships
Results are described of experiments carried out in Thunder Bay Harbour in March, 1984, to measure ice forces on a port structure. Ice forces were measured by installing five pressure...
Cost-Effective Arctic Concrete Structures
The economic development of offshore Arctic petroleum fields dictates that Arctic structures be both cost-effective and deliverable with minimum lead time. Concrete structures are typically...
Coastal Erosion's Impact on California Offshore Oil Development
Recent oil discoveries in the offshore Santa Maria Basin and the Santa Barbara Channel will require the construction of new oil facilities located along 90 miles of Santa Barbara County...
The Impact of Selected Sea Level Rise Scenarios on the Beach and Coastal Structures at Sea Bright, N.J.
The physical impacts of selected sea level rise scenarios on the shoreline of Sea Bright, New Jersey, are investigated. The sea level rise scenarios chosen for investigation were developed...
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...
Mini Hydro at Low Cost
The Kingsley Dam is an existing irrigation dam that has been retrofitted with electric generating capacity. The project was completed 6 months ahead of schedule without interrupting irrigation...
Management Secrets of Top Consultants
Leaders of five consulting civil engineering firms, which are considered among the best managed, discuss management strategies. In all cases, carefully selected personnel is considered...
Maintaining a Natural Gas Pipeline in Active Landslides
This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe...
Quality Control Management of Real-Time Data
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. This paper presents several data verification...
Initial Operation Model for the Central Arizona Project
A microcomputer program for operating uncompleted portions of the Central Arizona Project has been developed. Engineers may use this program daily to assist in scheduling pumping plant...
Retrofit Services: Responding to Today's Market
As a result of the decline in demand for new nuclear power plant construction the nuclear industry has experienced a major change in the nature of business opportunities. To meet the rising...
Decentralization of Nuclear Power Plant Engineering
The cost of nuclear power construction in the past two decades has increased by an order of magnitude, forcing utilities and A/E's to look for ways to reduce engineering and...
Seismic Pope Support Construction Practices
During the mid 1970's the regulatory agencies controlling the design and construction of nuclear power plants began to demand stricter adherence to already existing codes...
Nuclear Power Plant Delays: Probable Causes and Resolutions
The nuclear power industry in the United States is experiencing technological as well as construction and operation problems in nuclear facilities. It is the intent of this paper to review...
The Prudency Management Audit: A New Challenge for the Civil Engineer
The Nuclear Industry, particularly utilities and their constructor, engineering and vendor agents, is faced with a surging increase in Prudency Management Audits. Such Audits are often...
