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...
Water Jets: Concrete Yes, Tunneling Maybe
High pressure water jets are demolishing concrete from bridge and parking decks, faster and at lower cost than by traditional means. The technique is fast becoming an acceptable option....
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...
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
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...
Evaluation of and Recommendations for Drop Structures in the Denver Metropolitan Area
In 1982, the Denver Urban Drainage and Flood Control District published interim guidelines for the design of sloped, loose riprap drop structures, as well as vertical wall drop structures...
Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
Air Regulated Siphons as Irrigation Canal Outlets
This paper investigates the possibility of using air regulated siphons as outlets from irrigation canals. Although a solution to a specific problem is sought, it is recognized that the...
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...
