Port of Seattle Seismic Waterfront Design
This paper describes the soil seismic design process, using the design developed for a concrete apron project at Terminal 20 as an illustration. Damage by the 1965 earthquake is described....
Performance of Water and Sewer Lifelines in the May 2, 1983 Coalinga, California Earthquake
Water supply and filtration systems for the City of Coalinga suffered little damage. The water transmission system suffered five breaks. The urban distribution system was disrupted, but...
Intermountain Power Project Seismic Design
Coal-fueled generation units of the Intermountain Power Project are constructed in a seismically active area of Utah (UBC Zone 3). The seismic design criteria were published during the...
An Overview of Earthquake Design Requirements at Pacific Bell
Seismic design considerations for the telephone system including outside plant and telephone equipment are discussed with emphasis placed on the requirements incorporated in the design...
Seismic Risk and Reliability of Telecommunications Systems
A general method for seismic risk analysis of telecommunications sytems evaluates by statistical means the earthquake environment and the earthquake vulnerability and effects on the system...
Retaining Wall
The foundation of this off-ramp in Manchester, New Hampshire is made up of end-bearing piles and sloping rock anchors�an innovation that is unique to the United States. End bearing piles...
A Systematic Approach to Conducting Seismic Margin Reviews for Nuclear Power Plants
Deviations from the current codes and standards are considered acceptable in a SMR in areas where the design criteria impose significant conservatism provided the intended function of...
Update on Impact Effects in Nuclear Plants Part I?Overview and Need for Integrated Approach
In this paper, an ASCE working group on impact effects in nuclear plants updates the review of this technology contained in a five-year-old ASCE report. In Part I, an overview is given...
Update on Impact Effects in Nuclear Plants Part III?Review of Heavy Object Drop
The consequences of an accidental drop of a heavy component from a lifting device in a nuclear power plant are required to be evaluated even though the device may have been designed using...
Pipe Impact on Concrete Slabs
A series of pipe impact on concrete slab tests have been performed at the CEA's Cadarache Laboratory using the AQUITAINE II facility. The testing program was jointly sponsored...
Probabilistic Analysis of Impact Loading Conditions
Probabilistic methods are developed for the analysis of random impact loading conditions that arise from oblique, noncollinear, and spinning missile impacts. Models are developed for the...
Low Velocity Impact Tests on Reinforced Concrete Panels
The results of low velocity impact tests on reinforced concrete panels are presented. These tests were conducted to investigate the behavior of reinforced concrete flexural elements subjected...
Behavior of an Operating Floor Subjected to Heavy Load Drops
A structural evaluation of the behavior of a Boiling Water Reactor operating floor subjected to postulated heavy load impact is presented relative to the evaluation of nuclear industry...
Computer-Aided Load Monitoring System for Nuclear Power Plant Steel Framing Structures
The design of nuclear power plant steel framing structures is a long and involved process. It is often complicated by numerous changes in design loads as a result of additions, deletions...
Reliability Assessment of Indian Point Unit 3 Containment Structure Under Combined Loads
In the current design criteria, the load combinations specified for design of concrete containment structures are in the deterministic format. However, by applying the probability-based...
Seismic Evaluation of Reinforced Masonry Walls
Masonry walls in operating nuclear plants are in many cases found to be overstressed in terms of allowable stresses when evaluated using current seismic design criteria. However, experimental...
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 Use of Joint Reinforcement in Qualifying Masonry Walls in Nuclear Power Plants
Wire joint reinforcement has been traditionally used in block masonry walls for crack control and to provide continuity for multiple wythe walls. In a number of nuclear power plants, vertically...
Probabilistic Seismic Analysis of a Nuclear Power Plant Steel Containment
Concern for the safety of nuclear power plants has motivated efforts to determine the statistical characteristics of the seismic resistance of steel containments under various types of...
A Study of the Correlation of the Components of Instructure Motions During Earthquakes
Thirty-two buildings are selected that have all three components of motion recorded in the basement, midheight and top of the structure. The correlation coefficients of these motions,...
