Effects of Damage and Redundancy on Structural Performance
There are numerous factors involved in the interrelationship between damage states, redundancy, system strength and structural performance. This volume examines some of these factors and...
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...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
Guide for the Design and Use of Concrete Poles
Prepared by the Concrete Pole Task Committee of the Committee on Electrical Transmission Structures of the Structural Division of ASCE. This guide presents...
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
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...
Making Embassies Safe for Democracy
American interests overseas have become among the most popular targets for terrorist attacks. Once, not long ago, security was only an afterthought for such facilities. Today, $4.4 billion...
Sound Structure
A new concert hall in Dallas, Tex., has the first acoustical design done with the aid of computer simulations that also dictated the shape of the performance space. Those dictates, in...
Historic Bridges: Conflict Ahead
The engineer who deals with historic bridges becomes the focus of controversy in the course of determining the existing condition, predicting remaining useful life, and designing the repair...
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...
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...
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...
Neyrtec Automatic Equipment for Irrigation Canals
The French Company ALSTHOM has developed a line of simple equipment for automatic level control and constant discharge control in canal irrigation systems. The paper includes a description...
Controlled-leak Methods for Water Level Control
The controlled-leak methods are a group of similar techniques for controlling upstream water levels, downstream water levels, or offtake canal discharges. They require no electrical power...
Automated Water Control in Southern Alberta
The distributed control system for water delivery that has evolved in Alberta, Canada is described including the type of hardware used and the general operating philosophy. Of importance...
Bival System for Downstream Control
The BIVAL system of canal regulation guarantees that the maximum discharge can be delivered at any time, as for downstream control systems and, moreover, it minimizes the canal dyking...
Canal Automation Using the Electronic Filter Level Offset (EL-FLO) Method
Beginning in 1969, the Bureau of Reclamation began testing and refining an electronic filter level offset (EL-FLO) control system for canal automation. The control system uses a proportional...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
Design of Semi-Closed Pipeline Systems
Semi-closed pipeline systems controlled by downstream activated float valves permit low pressure pipeline systems to communicate information from the outflow location back to the source...
