New Developments in Seismic Analysis of Primary and Secondary Systems
This paper presents recent advances made at NCSU in the seismic analysis of these systems. Algorithms are presented by which coupled mode shapes and frequencies can be evaluated without...
Evaluation of the Ultimate Pressure Capacity of Rectangular HVAC Ducts for Nuclear Power Plants
Structural design criteria are presently based on the AISI Code which limits the duct panel width-to-thickness ratio to a maximum of 500 and the maximum height-to-thickness ratio to 200,...
Composite-System Approach for Seismic Analysis of Secondary Systems
An accurate and efficient method for seismic analysis of multiply supported, multi-degree-of-freedom secondary subsystems is developed. The method accurately accounts for the effects of...
A Computer Integrated Engineering System for Nuclear Plant Design
The design, construction, and licensing of nuclear power facilities is a long and complicated process which can span a time period of over ten years. This tremendous lead time to plant...
Slurry Pipeline Control Systems
The paper documents the La Perla-Hercules pipeline and its control system. This eight and fourteen-inch, 382-kilometer iron ore concentrate slurry pipeline was commissioned in June of...
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...
Automatic Controls for Industrial Water System
An 8-mile pipeline and associated facilities along its route are controlled by a centralized system consisting of a master station and four remotes. Each site employs Westinghouse programmable...
Security of Unattended Pipeline Stations
The ultimate purpose of a security system is to maintain equipment and service in a normal operating condition or to restore the equipment and service to normal operating condition as...
Ground Water Economics in the San Joaquin Valley
Ground water pumping in the San Joaquin Valley to supplement surface water supplies has increased from about 200 thousand acre-feet per year at the beginning of this century to nine million...
The Present Status of Application of the Plastic Concepts in Structural Design
The different approaches of recognizing plastic behavior in the design of steel structures are reviewed and the design requirements that assure successful utilization of this behavior...
Probing the Past
In Denver, Colorado, 12 buildings of an old abandoned brewery complex were to be renovated into a 270,000 sq ft shopping, entertainment and restaurant complex. Rather than conduct a thorough...
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....
