ASCE Salary Survey 1991
The 21st biennial ASCE salary survey of the engineering profession conducted by the ASCE Committee on Employment Conditions during the first half of 1991 is presented. It consists of an...

Autocorrelation Functions for Offshore Geotechnical Data
Autocorrelation functions are described. Data from several North Sea sites are analyzed with respect to the vertical and horizontal autocorrelation of a number of soil properties. Based...

Bayesian Updating of Axial Capacity of Single Pile
The paper outlines a Bayesian technique to update predictions of pile driving and axial pile capacity on the basis of pile driving records. The approach enables one to systematically account...

Largest and Characteristic Earthquakes in the U.S. East of the Rocky Mountains
A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...

Variability of Parameters of Earthquake Ground Motion Recorded by Strong Motion Arrays
The spatial variation of scalar measures of earthquake ground motion, such as peak ground acceleration, strong motion duration, and root-mean-square amplitude, along with various spectral...

System Reliability of Semi-Submersible Platforms
This paper deals with the system reliability of semisubmersible platforms which are modelled as spatial frames and subjected to quasi-static extreme loads based on elasto-plastic strength...

Risk Assessment of Utility Network Systems Using Expert Opinions
This paper describes the application of an expert opinion and survey approach to the problem identification and risk assessment of engineering systems. The method of expert opinion for...

Durability and Damage Tolerance Evaluations of Jet Transport Structures
Many design considerations are involved in ensuring structural integrity of Boeing jet transports, which have common design features validated by extensive analyses, tests, and service...

Stochastic Finite Element Analysis for Spatial Variations of Soil Properties Using Kriging Technique
When a reliability analysis for geotechnical problems is performed based on the stochastic finite element method, a proper estimation of spatial variation of soil properties is important...

A Comparison of Different Mathematical Models for the Spatial Correlation of Distributed Excitation Forces
This paper contains an investigation of the transverse vibrations of EULER-BERNOULLI beams under longitudinal tension and random space-time loading. Using GREEN's function...

Probabilistic Analysis of the Ghonem and Dore Data
A two-state Markov process model for fatigue crack growth is utilized with experimental fatigue crack growth data reported by H. Ghonem and S. Dore to study the effect of stress ratio...

Two Principles for Data Based Probabilistic System Analysis
A major problem in probabilistic system analysis is to find a self-consistent method of inference about probabilities based on a random sample of system state variables. Such a method...

The Extremes of Combinations of Environmental Loads
The objectives and the general approach of an offshore environmental data and extremal analysis are described. The intention is to develop long-term design values of wave, wind and current...

Statistical Analysis of Australian Ground Snow Loads
This paper is concerned with the statistical analysis of snow data from the alpine areas of southeastern Australia (above 1200 m). In these areas, the local variation is large and contour...

Analysis of Bridge Maintenance and Rating Procedures
In the United States, bridges are routinely rated to evaluate their existing conditions. The formula used to evaluate bridges is called the Sufficiency Rating Formula. The formula uses...

Bayesian Reliability Analysis of Structures with Multiple Components
This study develops a method of Bayesian reliability analysis to establish an optimal inspection schedule of structures with multiple components using the data collected during inservice...
