Smoothwall Blasting Planned for the Underground Research Facility at Yucca Mountain
At this time it is not known whether the Exploratory Shaft Facility (ESF) at Yucca Mountain, Nevada will be completely mechanically excavated, completely developed by drilling and blasting...
Pre-Experiments of OTEC Experimental Facility for Ocean-Based Mariculture-OTEC Pilot Plant Houyou
The ocean-based mariculture-OTEC pilot plant 'HOUYOU' was completed in March, 1989 and the at-sea test in Toyama Bay was carried out from July 18th until September...
Long-Term Strength Gain or High Strength Concrete as Monitored by Drilled Cores
An evaluation was made of the relationship between standard cylinders, four-inch by eight-inch cylinders, and drilled cores. The evaluation results showed that the strengths obtained from...
70 Year Performance Record for High Strength Structural Lightweight Concrete
The paper briefly discusses the first ship built using expanded aggregates manufactured in a rotary kiln the USS Selma. It then goes on to discuss achieving high strength concrete with...
Cables and Flexible Pipes in Contact with Sea Floor
Flexible offshore systems can be analyzed by a number of different techniques. The techniques described herein fall in the general category of finite element methods. Special cable elements...
The Fatigue Performance of Welded Joints in a Marine Environment
The fatigue lives of plate-plate, pipe-plate, and tubular welded joints tested in seawater under free corrosion, optimum cathodic protection and cathodic overprotection measured in the...
Inspection Strategies for Offshore Structures
The fatigue limit state is the governing limit state for the structural dimensions in several parts of offshore structures. Prediction of the fatigue life of tubular joints and other welded...
Effect of High Frequency Response on Fatigue of Offshore Structures
Welded steel specimens have been tested under several loading spectra to determine the effect on fatigue life of high frequency components in the psd of the stress or strain in the joint....
Low-Cycle Fatigue Reliability of Offshore Structures Subjected to Earthquakes
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability...
Modal Parameter Identification of an Offshore Platform from Earthquake Response Records
The Whittier Narrows earthquake on October 1, 1987, was recorded by the earthquake monitoring system on an offshore platform installed in a water depth of 97 m in the Santa Barbara Channel....
Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...
CUFAD: A Computer Program for
A research effort within the electric utility industry has focused on unified design methods for axially loaded foundations for transmission line structures. This research has been made...
Uncertainties in Offshore Axial Pile Capacity
The overall bias and error associated with the API recommended procedures and other popular methods for offshore pile design are evaluated. The paper considers single axial friction piles...
Some Observations on Undrained Side Resistance of Drilled Shafts
A data base of 106 field load tests (65 in uplift and 41 in compression) is used to evaluate the undrained side resistance of drilled shaft foundations. The total stress or alpha (?) method...
New Design Method for Drilled Shafts from Common Soil and Rock Tests
A method is presented by which the compressive capacity and load-settlement characteristics of large drilled shafts can be computed from commonly executed soil and rock tests. The method...
Drilled Shafts?A Database Approach
A database of 43 drilled shaft load tests of high quality has been developed to study parameters that affect the axial behavior of drilled shafts and methods of analysis to predict axial...
Interpretation of Load Tests on Drilled Shafts?Part 1: Axial Compression
Existing interpretation methods for axial compression load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A simplified method,...
