Distributional Information for Ejection Fragments
Due to lack of experience of building structures on the lunar surface and the variability that will exist in the loading as well as the structural resistance, it is suggested that initial...

JSC-1: A New Lunar Soil Simulant
A new lunar soil simulant, JSC-1, has been developed and characterized under the auspices of the NASA Johnson Space Center. This simulant was produced in large quantities to satisfy the...

Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...

Response of Stressed Timber T - and Box-Beam Bridges
The objective of this study is to establish the strength, stiffness, and transverse load distribution factors of stressed timber T-, Bulk T-, and Box-beam bridge systems. To achieve the...

Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...

Assessing Effects for Disposal Sites off San Francisco
A simple particle tracking model has been used to estimate the size of deposition footprints and transient turbidity effects in the water column resulting from disposal of dredged material...

Sensitivity of Great Lakes Forecasting System Nowcasts to Meteorological Fields and Model Parameters
The Great Lakes Forecasting System is being developed by the NOAA Great Lakes Environmental Research Laboratory and Ohio State University. It uses meteorological fields as input to a numerical...

Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...

Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...

Willingness-to-Pay for Alternative Shortage Probability Distributions
Mathematical programming is used to derive estimates of the willingness-to-pay of water service customers for improvements in water supply reliability. Reliability is represented as a...

Homogeneity Tests Based Upon Gumbel Distribution
This paper analyzes the performance of three homogeneity tests for Gumbel distributed flood flows. The classic Dalrymple test, a method-of-moment Cv test, and a normalized-quantile test...

A Regional Model of Daily Streamflow for the Northeast United States
A regional flow duration curve (FDC) model is under development which relates daily streamflow at 166 unregulated basins in the northeastern U.S. to watershed and climatic characteristics....

A Computational Algorithm for Analysis of Rectangular Footings Under Partial Contact with Soil
This paper describes a method to determine the distribution of base pressures under a rectangular footing experiencing partial contact of the footing with soil. Assuming the footing to...

A Flexible Structural Analysis Method for Computer-Aided Preliminary Design
This paper presents a new method for supporting structural analysis during preliminary design stage that is based on Gere's idea of 'moment distribution'. The extension is that in this...

Model Tests on Caissons
Laboratory tests were conducted on model caissons to better understand the settlement/deflection behavior of open ended caissons on sandy soil, with embedment depth, caisson diameter,...

Deformation of Sand Foundations Induced by Earthquakes
This paper discusses the deformation of sand foundations during earthquakes based on the experimental results of centrifuge tests. A group of tests was conducted on two types of buildings...

Consolidation Settlements and Pore Pressure Dissipation
A test fill was constructed off the coast of one of the outer islands in Hong Kong to evaluate the consolidation characteristics of a soft plastic clay deposit known as Hong Kong mud....

Vacuum consolidation Technology?Principles and Field Experience
Vacuum consolidation is an effective means for improvement of saturated soft soils. The soil site is covered with an airtight membrane and a vacuum is created underneath it by using a...

When and How Can You Specify a Probability Distribution When You Don't Know Much?
This paper presents an excerpt from the proceedings of the above-named workshop, and gives an overview of both the workshop and the proceedings. Five papers with diverse and complementary...

Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...
