Study of Failures of Towers and Tall Buildings Under Wind Loading
In this paper, two kinds of wind-excited limit states on a tall structure are investigated and corresponding formulae for the limit wind pressures are presented. In solving the wind-excited...
Neural Networks in Structural Control
Let the response of a simple two-story frame to a stochastic dynamic excitation be controlled by activating suitable actuators. A neural network is trained to recognize, from the measurement...
Conceptual Design of a Monitoring System for Maglev Guideways
The state-of-the-art in nondestructive testing (NDT) technology has advanced significantly over the past fifteen years and has reached a stage where continuous monitoring of structures...
Serviceability Reliability Analysis of Wood Beams
The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the...
Fatigue Damage Accumulation Under Non-Gaussian Loads
The stochastic fatigue life prediction method, namely the Rayleigh approximation method, is almost exact when the loading is both normal (Gaussian) and narrowband. However, in many realistic...
Time Variant Reliability Under Environmental Loads
Time variant reliability with deteriorating resistance under a stochastic load process is considered. An outcrossing formulation for fatigue degradation is presented, and a simple and...
Evaluation and Rehabilitation of Relief Wells
The U.S. Army Engineer District, Vicksburg has developed an expedient method of rehabilitating arrays of large numbers of gravity flowing relief wells located along the toe of dams using...
Development of High Performnance Shotcrete (Theoretical Considerations)
This paper presents some theoretical considerations for studies on high performance wet-mix shotcrete. A new laboratory shotcrete pump and rheometer are being developed to study the effects...
A Comparative Study of Different Steel Fibers in Shotcrete
Two steel fiber reinforced shotcrete (sfrs) test programs have been carried out in eastern Canada using steel fibers which are available in the north American marketplace. The first program...
Shotcrete for Underground Support V
This proceedings consists of papers presented at the Engineering Foundation Conference held in Uppsala, Sweden on June 3-7, 1990. They are divided into sections concerned with the design...
An Assessment of Coupled Thermal-Hydrologic-Mechanical-Chemical Processes
A literature review was conducted to determine the state of knowledge available in the modeling of coupled thermal (T), hydrologic (H), mechanical (M), and chemical (C) processes relevant...
Experience in Modeling for Environmental Physics and Biogeochemistry
This report is a short review of the author's personal experience on phys.-math. and system-logical modeling of migration and transport processes (MTP) of radionuclides, trace-elements...
Effect of Interconnection of Fractures on Dispersion in Flow Through Fractured Networks
A stochastic modeling technique in a 2-D discrete fracture network with two orthogonal sets of fractures is developed to investigate mass transport dispersion and to investigate the relation...
Disposal of Defense Spent Fuel and HLW from the Idaho Chemical Processing Plant
Acidic high-level radioactive waste (HLW) resulting from fuel reprocessing at the Idaho Chemical Processing Plant (ICPP) for the U. S. Department of Energy (DOE) has been solidified to...
Remote Spent Fuel Handling in France at the La Hague Cask Unloading Facility
French policy for the back end of fuel cycle is based on spent fuel reprocessing. Irradiated spent fuels are transferred in casks from the nuclear reactors to the reprocessing plant where...
Treatment of Non Fuel Bearing Scrap
Problems encountered with the processing of irradiated non fuel bearing components (NFBC) during several rod consolidation demonstration programs identified the need to conduct further...
Non-Fuel Bearing Hardward Melting Technology
Battelle has developed a portable hardware melter concept that would allow spent fuel rod consolidation operations at commercial nuclear power plants to provide significantly more storage...
Recent Developments in Stochastic Modeling and Upscaling of Hydrologic Properties in Tuff
A set of detailed geostatistical simulations of porosity has been produced for a layered stratigraphic sequence of welded and non-welded volcanic tuffs at Yucca Mountain, Nevada. The simulations...
Stochastic Simulation of Mass Transport in Heterogeneous Formations Using Hard and Soft Conductivity Data
The mass transport in a synthetic 2-D heterogeneous formation is simulated through the Monte-Carlo method using continuum approach. The simulated hydraulic conductivity field are generated...
The Independent Cost Estimating Process
The United States Department of Energy (DOE) requires that an Independent Cost Estimate (ICE) be prepared for all Major Systems Acquisitions (MSAs); that is, projects or programs expected...
