Time Management for Engineers and Constructors
This book is the first in a series which focuses on engineers' management needs. It presents time management principles for the practicing engineer and constructor, in a concise,...
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...
Knowledge Acquisition in Civil Engineering
Expert systems are an intriguing approach for transferring valuable problem-solving skills from the minds of human experts to the logic of computer programs. For the past several years,...

Man and Huge System Interaction
In many cases of disaster, the causes of failure of huge systems are frequently attributed to human error. However human is liable to error. To exclude human factor from a huge system...
Identification of Critical Load Distributions for Wind Loading
For practical application as well as for sophisticated investigations, the time dependent stochastic wind process has to be simplified in terms of input data to the calculation. Usually,...
Optimal Distribution of Tuned Mass Dampers in Wind-Sensitive Structures
Modern high-rise buildings are susceptible to excessive accelerations at the upper floors in wind storms due to flexibility and low damping. In order to keep acceleration levels below...
Reliability of Bridges in Turbulent Wind
The present study investigates the stability of bridge motion by means of almost sure or sample stability criteria. An asymptotically exact approximation for the top Lyapunov exponent...
Wind Loads on Large Broadcasting Antennas: Records and Elaborations
Alternative estimations of the 50-year gust winds from the data available in typical Italian sites of broadcasting antennas are summarized and compared with the design winds suggested...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
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...
Near-Field Differential Ground Displacement
An analytical model for the development of differential ground motions in the vicinity of a vertical, strike-slip fault is presented. The model considers a uniform, kinematic source model,...
Earthquake Clustering in the Kanto District
Earthquakes in the Kanto district (Japan) between January 1983 and March 1987 are analysed for the identification of independent main shocks and for the hierarchical clustering of secondary...
Examples of System Optimization and Reliability in Bridge Design
The objective of this paper is to present examples of system optimization and reliability in bridge inelastic design. The optimum solution is defined as the bridge of least weight, subject...
Large Monte Carlo Simulation of Duffing Equation
This effort aims to obtain some accurate statistics of the Duffing Equation subjected to white noise through Monte Carlo simulation. The results obtained can be used to check the accuracy...
Some Insight in Autoregressive (AR) Spectral Modeling
The difficulties associated with the determination of reliable autoregressive (AR) approximations of the Pierson-Moskowitz and Davenport spectra are examined from the standpoint of developing...
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...
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...
