Redecking with Precast Keeps Traffic Moving
The Woodrow Wilson Memorial Bridge in Washington, D.C. could not be closed to traffic while a new deck was constructed. The engineers designed a precast prestressed and post-tensioned...
Rail and Road Traffic Continue During Bridge Modification
The crossing of Route 15 under the Bangor and Aroostook Railroad Bridge, Bangor, Maine had limited sight distance and marginal clearances. Maine Department of Transportation, therefore,...
Computing in Civil Engineering
A broad spectrum of computer applications in civil engineering is covered in 73 papers presented at the Third Conference on Computing in Civil Engineering. Emphasis is on microcompters...
Repair�Don't Replace�Cracked Sewer Pipe
Approximately 0.5 mile (0.8 km) of 42 in. (1,07 m) diameter reinforced concrete was installed for a sanitary sewer project when the on site inspector discovered that numerous joints had...
Emerging Computer Techniques in Stormwater and Flood Management
These proceedings identify and assemble information on recent applications of mini- and microcomputer technology to problems in urban stormwater and flood management. Instrumentation and...
Traffic Reroute
During reconstruction of Pittsburgh's Interstate 376, traffic and passenger diversion efforts, more extensive than ever before, were undertaken. Eight percent of the $62 million...
Seismic Qualification of Main Control Boards by Combined Mathematical Model and In-situ Modal Test
By adjusting the stiffness of the model, mode shapes and frequencies can be matched to those from the in-situ tests, thus giving a verified and representative model. With the verified...
Seismic Capacities of Masonry Walls at the Big Rock Point Nuclear Generating Plant
An evaluation to determine the ability of selected concrete block walls in the vicinity of essential equipment to withstand seismic excitation was conducted. The seismic input to the walls...
The Response of Steel Containment Models to Internal Pressurization
To obtain insight and data on the response of containment vessels subjected to beyond design basis accidents, four 1/32 scale steel containment models have been subjected to internal overpressurization,...
Preliminary Analysis of Large Penetration Enclosures for Containment Vessels Subject to Beyond Design Basis Loadings
Numerical simulations of the macro-deformations of the sealing surfaces (gasketed junctures) of a PWR steel containment vessel's equipment hatch subjected to accident loadings...
Major Considerations in Scale Modeling of Reinforced Concrete Containment Structures
Reinforced concrete containment structures pose unique modeling problems, especially when leakage integrity is of interest. This paper presents a general discussion of modeling considerations...
Allen-McColloch Pipeline Computer Based Control System
The Allen McColloch Pipeline (AMP) was designed to deliver 416 cfs of treated water from the Metropolitan Water District of Southern California's Diemer Water Treatment Plant...
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...
San Joaquin Valley Hydrologic-Economic Model
The rapid development of agriculture in the San Joaquin Valley has resulted in increased ground water pumpage. Increasing energy costs coupled with increasing pumping lifts have a major...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
