Seismic Considerations for the Century Freeway
The Century freeway (Interstate 105), will be an 18 mile (29 km) long, six-lane facility with 2 central transit/HOV lanes, located in Los Angeles, California. The freeway alignment crosses...
Base Isolation Concepts for Seismic Bridge Retrofit
Failures in past earthquakes have indicated three major problem areas with existing bridges. The first is the vulnerability of existing rocker and roller type bearings and this is coupled...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
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...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In 1980, the Nuclear Regulatory Commission (NRC) designated Unresolved Safety Issue (USI) A-46 to address the seismic safety of equipment in operating nuclear power plants. In 1982, the...
Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...
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...
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...
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...
Capability of LMFBR Plant Structures Beyond the Design Base
A study is presented concerning the capability of structures in a loop type Liquid Metal Fast Breeder Reactor Plant, the Clinch River Breeder Reactor Plant (CRBRP), to sustain conditions...
Reduction of Seismic Response in Breeder Plants
Thin-walled vessels to be used in the Nuclear Steam Supply Systems (NSSS) of future LMFBR's will be more sensitive to seismic excitation than their equivalents used in conventional...
Experimental Determination of Fluid-Coupling Coefficients in an Array of Hexagonal Prisms
The problem is related to the seismic analysis of fast breeder reactor cores, where the fluid trapped between the subassemblies is known to have a considerable influence on the core response....
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...
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...
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...
