A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In December of 1980, the Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46 to address the question of the seismic adequacy of equipment in 49 operating nuclear...
Obtaining Reliable Data from Fragility Tests
The parameters discussed in this paper are the same as those present in normal seismic qualification testing. These parameters behave differently in high level acceleration tests and their...
Earthquake Experience Data on Power and Industrial Structures: Applications to Seismic Design and Evaluation
An extensive study was conducted to document the seismic performance of typical power plant and industrial structures in selected recent strong earthquakes and to correlate the performance...
Aseismic Capability Prediction from Failure Data
Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant...
Impact on Test by Various Multiaxis Excitation
The purpose of this paper is to provide input guidelines in evaluating various types of multiaxis excitation on fragility level testing of electronic devices. There are many variables...
Seismic Design-Qualification of Non-Safety Related Items in Safety Related Envelope
This presentation pertains to Seismic Design-Qualification for those portions of structures, systems, or components in a Nuclear Plant whose continued function is not required but whose...
Physical Evaluation of a Buried Drainage System
The drainage problem in the 600,000 acre (1. 5 million ha) Westlands Water District (District), located in the Central San Joaquin Valley in California is that of a perched saline groundwater...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Strength of Soils in Terms of Effective Stress
The factors that determine soil strength, such as amount of confinement, density, particle size distribution, mineral friction, aging, particle crushing, and others, produce their effects...
Recent Developments in Resonant Column Testing
The resonant column method of testing soils is reviewed. Recent developments in equipment, specimen configurations, and testing schemes are presented. Some equipment can perform both resonance...
Limits on Dynamic Measurements and Instrumentation
The implementation of the FFT (Fast Fourier Transform) into portable instrumentation has contributed to advances not only in signal analysis but also to new and improved transducers for...
Shallow Seismic Exploration in Soil Dynamics
Methods of shallow seismic exploration of soils are continually developing and evolving. Advances in techniques and equipment for performing crosshole and downhole tests, new data on interpretation...
Design of Structures to Resist Nuclear Weapons Effects
This manual provides guidance to engineers engaged in designing facilities intended to resist nuclear weapons effects. Although emphasis is placed on blast-resistant design, other effects...

The field of underground pipeline engineering has undergone a rapid growth during the last two decades. The analysis, design, construction, operation, and maintenance of underground pipelines...
Probabilistic Basis for Design Criteria in Reinforced Concrete
This collection of papers presents the results of research on the variability of reinforced concrete members carried out at the University of Alberta, Edmonton, Canada, during the period...
Connection Flexibility and Steel Frames
The papers included in this book introduce and present methodologies for the analysis and design of frames which take into account the effect of joint flexibility on the response characteristics...
Developments in New and Existing Materials
Materials engineering has emerged as an identifiable professional practice within civil engineering in the past few years. Although materials engineering is not new, the concept that this...
Fracture Problems in the Transportation Industry
Six cases of damage tolerance assessment are presented, involving structures or vehicles in the U.S. transportation industry. Damage tolerance means arranging design, maintenance, and...
Damage Mechanics and Continuum Modeling
Historically, the structural and mechanical engineers are conditioned to model a material in a purely phenomenological sense with little or no regard to underlying physical phenomenon...
