Structural Engineering and Microcomputers
This publication contains five papers on the use of microcomputers by structural engineers. The first paper discusses the design of multi-story rigid steel frames. The design process employed...
Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures
This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard...
Use of Vibration Measurements in Structural Evaluation
Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures...
Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...
The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...
Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...
Electronic Gymnastics
Efforts are being made to have all the parties to a project share the same, current information. In order to do so, civil engineering firms are jumping through electronic hoops to get...
Optimization: An Emerging Technology
The technology of formal, numerical structural optimization is neither mysterious nor complex. Software programs are now available for use by engineers who do not have detailed knowledge...
CAD Trials
The solo practitioner is, for many reasons, at a disadvantage when it comes to analyzing and selecting CAD system components. Trade magazine how-to articles are generally geared toward...
Worth a Thousand Words
In recent years, microcomputers have grown powerful enough to take over many of the functions that once, only a mainframe could understand. In addition, they have added a few tricks of...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Computers: What Do Students Need to Know?
This article is based on interviews with three professors at three universities, a recent graduate from each school, and the graduate's employer. The interviews show that...
Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...
Expert Systems for Risk Analysis
An explanation is presented on why construction risk analysis can be handled by an expert system computer program. The author offers a prototype construction risk management expert system...
Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...
Overview of Canal Control Concepts
An overview of terminology and philosophies of canal control, plus brief descriptions of canal automation technologies, is given. The justification given for examining control schemes...
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....
Air Chamber Surge Tanks in High Head Hydro Plants
The U. S. Army Corps of Engineers Alaska District considered an air chamber during the design of the 'Crater Lake phase of the Snettisham Project near Juneau, Alaska. A conventional...
A Stratified Mixing Channel: Theory and Experiment
The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is...
