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...
Foundations for Transmission Line Towers
This special technical publication contains the proceedings of a two session symposium on foundations for transmission line towers. These papers were written by researchers, geotechnical...
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...
Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...
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...
A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....
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...
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...
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...
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...
Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
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...
Pipeline Types and Design Considerations
Pipelines are extensively used to upgrade irrigation delivery facilities. The advantages of a pipeline system include an improvement in water conservation and the ability to extend water...
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...
Pump Plant Control and Automation
Pumping plants for irrigation systems can be separated into two general types: source pumps which provide water to the system and booster pumps which increase the system pressure. Typically,...
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...
Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...
Stepped Spillway Design with a RCC Dam
The hydraulic model study results for the Upper Stillwater stepped spillway design are presented. The studies encompassed several spillway geometries and design unit discharges ranging...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...
