As-Built Locations Through Precision Photography
This paper describes a new application of close range photogrammetry as a technique for obtaining reliable as-built locations of embedded threaded inserts in concrete structures and the...
Santa Clara Valley Weather Modification Program
This report describes a significant advancement in the Santa Clara Valley Water District's knowledge and understanding of its weather modification (cloudseeding) program,...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Performance of Low Stiffness Plastic Pipe in Stiff Soils
Large diameter pipe made from ductile plastics, such as polyvinyl chloride (PVC), polypropylene (PP) and high density polyethylene (HDPE) can be effectively utilized in subsurface installations...
Design Criteria for Buried Flexible Pipe
A modified CANDE program was used to analyze a full factorial set of design parameters for buried, large diameter high density polyethylene profile-wall pipe. A new pipe subroutine was...
Drip Irrigated Cotton: Economics and Water Savings
Groundwater withdrawals for cotton production in the arid Southwest account for about 15 percent of all groundwater withdrawals. In Arizona, cotton's proportion of groundwater...
Computer-Automated Limit-States-Design of Steel Frameworks
The paper concerns the computer-automated synthesis of minimum-weight planar steel frameworks. For any number of applied loading cases, the design of the structure may be constrained by...
Limit State Analysis of Lattice Steel Transmission Towers
The background and present status for limit state analysis of lattice steel towers at the Bonneville Power Administration is presented. Conceptual development, a computer program, and...
Evaluating Data Collectors as a Surveying Tool
Data collectors play an increasingly important role in surveying. The data collector serves as an interface between the total station and the computer and as an electronic assistant to...
Defining Productivity
The writer states that effectiveness, not efficiency, is the key to productivity. Efficiency is measured by how fast a task is accomplished. Effectiveness is determined by the importance...
Engineering Mechanics in Civil Engineering
The principles of engineering mechanics and the application of these principles to civil engineering problems cover a broad spectrum of topics ranging from theory to practice. These proceedings...
Quantifying Organization Goals in Project Planning
In this paper we develop and demonstrate the application of a goal programming model. It is designed to assist top management to incorporate the goals of an organization in allocating...
Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...
Prediction of Settlement of Single Piles in Clay
Analyses by trial were used to fit theoretical load-settlement curves to measured curves for driven piles. For the elastic method, analyses of load tests indicated that designers should...
Dynamic Stiffness of Pile Groups
A number of procedures have been proposed for the dynamic analysis of complete pile foundations including group effects. Most of these introduce some sort of approximation to reduce the...
Winkler Soil Model for Axial Response Analysis of Pile Groups
In this approach, the soil is idealized as a nonlinear Winkler model for a pile group attached to a group of piles. The model can account for pile-soil-pile interaction. Pile group responses...
Functional Specifications of a Distributed Engineering Data Management System
The development of a large-scale engineering data management system is outlined for AEC industries. Described are the outline specifications and basic design decisions used to implement...
Database Management
Computer aided design systems have found widespread acceptance from Engineering companies as drafting/detailing/drawing tools. While this has brought a dramatic productivity improvement...
Planning of CAE and CADD Centers
The factors to be considered prior to the establishment of computer aided engineering or computer aided design and drafting centers are discussed. It is noted that the critical issues...
Toward Interactive Color-Shaded Rendering in CAD
A software package (CATSIG) is described which allows the user to interactively color shade geometric objects created on a sophisticated commercial CAD system (CATIA). The novel features...
