Seismic Assessment of High-Rise Buildings
A method is presented by which the seismic resistance of a structure can be assessed and which leads to results with a rather high level of confidence. It is based on the notion of the...

Statistics of Liquefaction and SPT Results
Data are available on the field behavior of 39 cases involving the occurrence or nonoccurrence of liquefaction during earthquakes. The data from the 39 cases have been examined in a statistical...

Bidding Contingencies and Probabilities
Bidding contingencies are categorized into the following four groups: Mistakes; subjective uncertainties; objective uncertainties; and chance variations. In each case a formulation is...

Statistical Methods in Structural Fatigue
Because of the scatter of fatigue test data, statistical methods are required for the interpretation of the data. A method, which features the Weibull distribution as the basic statistical...

Peak Flood Discharge Confidence Limits
Confidence limits along with a lower bound for the corresponding level of confidence are developed for evaluating the effect of the sampling error on flood risk evaluation from base-flow...

Earthwork Quantities by Random Sampling
Statistical methods are applied to determine earthwork quantities. First, cut and fill areas are delineated and planimetered. Then, a table of random numbers is used to locate sample items...

New Distributions of Extreme Winds in the United States
Using methods previously reported, annual extreme wind speed data series were extended with recent records at airports and reduced to the standard 30-ft elevation. These were fitted by...

Airport Accessibility and Detroit Passengers
The effect of decreased accessibility on passenger usage of the Detroit airport is investigated using techniques of statistical inference. The purpose is to demonstrate the usefulness,...

Sample Size Estimates in Permeability Studies
An analysis of field determined permeability data was made that shows how sampling accuracy changes with both permeability and number of samples. An exponential relation was observed between...

Distributions of Extreme Winds in the United States
Annual extreme wind speed data for airports in United States were corrected for anemometer type and reduced to standard 30 ft elevation; Fisher-Tippett Type II distribution was fitted,...

Distribution of Extreme Winds in the United States
Following previous work, annual extreme wind speed data for airports in the United States were corrected for anemometer type and reduced to a standard 30-ft elevation. The Fisher-Tippett...
