Stochastic Critical Excitations
Conventional methods of seismic analysis of structures frequently use the response spectrum or time history analysis techniques. The excitations for the time history analysis can be either...
Earthquake Damage Repair and Retrofit of the Seventh St. Terminal Port of Oakland
The October 17, 1989 earthquake resulted in the collapse of the two-level Cypress St. Freeway in Oakland. Television and newspaper coverage revealed the tragic loss of life and property...
Masonry as a Structural Material
Four case studies are presented which illustrate the use of masonry as a structural material. Results of laboratory studies for unreinforced piers subjected to in-plane lateral forces,...
Seattle Plays It Safe
To ensure the reliability of its aging water system in a major earthquake, the Seattle Water Department commissioned a comprehensive assessment of the system's seismic reliability...
Earthquake Hazard Investigative Procedures for Central United States Waterworks
The vulnerability assessment of Central United States waterworks for earthquake hazards is a developing engineering practice for civil engineers in Arkansas, Missouri and states close...
Seismic Mitigation of the Memphis Water System
Memphis, Tennessee is located in zone 2 of the 1988 Standard Building Code, close to the New Madrid Seismic Zone. The probability of having a seismic event of significant magnitude is...
Impact on Water Supply of a Seismically Damaged Water Delivery System
This paper presents the damage evaluation of a water delivery system caused by the ground shaking in the event of an earthquake by using the LIFELINE-W computer program. The adequacy of...
Seismic Hazards in the Eastern U.S. and the Impact on Transportation Lifelines
In the eastern US seismicity is low, hazard is moderate, and risk is quite high, especially in metropolitan regions with vulnerable transportation systems typically not designed to resist...
Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...
An Assessment of Environmental Costs Associated with Crude Oil Pipeline Damage Caused by Earthquakes
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks caused by earthquakes. Risk is measured both as volume of oil released and...
Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...
Lifeline Earthquake Engineering in the Central and Eastern U.S.

Earthquakes: A New Look at Cracked Masonry
Economics, fears of liability, and a strict damaged-buildings repairs ordinance have contributed to an extensive delay in the repair of masonry-infill buildings in earthquake-stricken...
Introduction to Structural and Mechanical Failure Modes for Nuclear Power Facilities
The three papers presented in this section discuss the types of information (i.e., dynamic tests, earthquake experience and analytical data) which are used in predicting the capacity of...
An Empirical Data Base for the Investigation of Earthquake-Related Changes in Crustal Hydrology
Both fracture permeability and fluid flow velocity can alter as a result of sudden strain changes associated with earthquake fault rupture. Testing the hydrological signatures of numerous...
A Prototype of the Uniform Building Code Using Hypertext
The earthquake section of the Uniform Building Code has been implemented using the hypertext technology. The information was broken down into many interrelated nodes. Figures were scanned...
Accurate Response Analysis of Seismic Distributed Mass Systems
A dynamic analysis technique of distributed mass structures is presented with a combination of the dynamic load factor approach and the dynamic stiffness matrix method. The dynamic stiffness...
An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
Computer Implementation of Seismic Building Codes
The objective of this work is to implement the provisions of building codes current in the U.S. as well as those of other countries for the seismic resistant design of buildings. The work...
Macro-Model for Inelastic Low-Rise R.C. Shear Walls
This paper presents an analytical technique for calculating static and seismic response of low-rise shear wall structures. The displacement response is resulting from bending, shear, and...
