The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....

Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...

Scour Analysis for Bridges over Missouri and Mississippi Rivers
Engineering services are being provided for three bridge crossings, two over the Missouri River and the other over the Mississippi River. Scour consideration for the bridged waterways...

Water Surface Profile Computations?How Many Sections do I Need?
One-dimensional streamflow models, including standard-step models, require a sufficient number of cross sections to satisfy two needs. First, a sufficient number of cross sections must...

A Study of Lateral Bed Slopes Developed at Bend
A study was conducted to compare seven actual cross section profiles of Philip Bayou Realignment with the lateral bed slopes estimated from the model derived by Ikeda titled `Sediment...

Emergency Protection, San Luis Rey River Aqueducts
A calibrated hydraulic computer model (FLUVIAL-12) was used to predict flood damage potential at the two San Diego Aqueduct river crossings in northern San Diego County. Model results...

Bridge-Scour Analysis Using the Water-Surface Profile (WSPRO) Model
A program was developed to extract hydraulic information required for bridge-scour computations, from the Water-Surface Profile computation model (WSPRO). The program is written in compiled...

Measurement of Bridge Scour at the SR-32 Crossing of the Sacramento River at Hamilton City, California, 1987-92
A study of the State Route 32 crossing of the Sacramento River near Hamilton City, California, is being made to determine those channel and bridge factors that contribute to scour at the...

The Definition of a Short Composite Column
A `short' column in composite construction is defined as one which can be designed for its cross-section strength alone without the need to consider stability effects. An extensive study...

Pipelines Crossing Highways and Railroads by Tunneling
When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by...

Inflatable Structures of Non-Circular Cross Section
This paper discusses six approaches to achieve an inflatable structure of non-circular cross section for use in lunar base development. Other papers have examined potential multiple uses...

Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...

Introduction to Immersed Tube Tunneling Symposium
Today's Symposium on Immersed Tube Tunneling is a continuation of a series of papers that began at Construction Congress '89 with discussion of mined tunnel subaqueous...

Seismic Hazard Along a Crude Oil Pipeline in the Event of an 1811-1812 Type New Madrid Earthquake
This paper presents an assessment of the seismic hazard that exists along a major crude oil pipeline (pipeline 22). An 1811-1812 type New Madrid earthquake with moment magnitude 8.2 is...

Liquefaction Hazard Analysis for Design of the Kern River Pipeline at the Muddy River Crossing, Southern Nevada
The 91.4-cm (36-in.) diameter Kern River natural gas transmission pipeline will cross the Muddy River in Moapa Valley, about 5 km west of Glendale, Nevada, in an area of relatively low...

Pipeline Field Experiment at Parkfield, CA
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed near Parkfield, CA. The site was chosen to capitalize on the predicted...

Whitfield Reservoir Inlet Outlet Pipeline
Alameda County Water District reports on the planning, design and construction of a 48-inch water main installed under modern urban circumstances. The location of the pipe and the construction...

Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...

Hydraulic and Scour Analysis for Muitiple Crossings of the Salt River, Phoenix, Arizona
Two new freeway systems currently being designed for the Phoenix metropolitan area, the East Papago Freeway and the Outer Loop Highway, will both cross the Salt River within a one mile...

Buckling of Variable Cross-Section Columns
An approximate solution for the problem of buckling of variable cross-section columns, loaded by variable axial force is given, for several boundary conditions. Both the cross-section...
