Engineering Liabilities for Design of a Bridge That Failed During the San Fernando Earthquake
On February 9, 1971, the San Fernando Valley in Southern California experienced a major earthquake. Among the victims were two men who were killed when a bridge connector ramp of a newly...

Seismic Design of Underground Structures Southern California Metro Rail Project
The effect of earthquakes on underground structures is the imposition of an arbitrary deformation which cannot be changed by strengthening the structure. The structural design goal is...

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...

Retrofitting Lifeline Facilities: The Japanese Approach
A brief history of the prediction of a major earthquake in the Tokai Area of Japan is reviewed. Planning and mitigation incorporating all levels of government and the private sector is...

CSMIP Strong-Motion Instrumentation and Records from Transportation Structures?Bridges
Seven transportation structures have been instrumented by the California Strong Motion Instrumentation Program (CSMIP), including four bridges. Records (in excess of 0. 25 g maximum acceleration)...

Seismic Design of Airport Control Towers
The paper describes state-of-the-art design in seismically active areas. It includes a review of current code design parameters and specific tower design criteria. Tower design examples...

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....

Seismic Response of Port and Harbor Facilities
A research program compiled information regarding the behavior of port and harbor facilities during past earthquakes. The potential for significant damage to port and harbor facilities...

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...

Dynamic Response Correlation of Cylindrical Tanks
The May 1983 Coalinga Earthquake provided an opportunity to correlate earthquake performance of cylindrical liquid storage tanks with behavior observed in laboratory shaking table experiments....

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...

Ocean Energy
The Ocean Thermal Energy Conversion (OTEC) component nominated this year as an ASCE Outstanding Civil Engineering Achievement involves the most critical design problem; the cold water...

Response of Subsystems on Inelastic Structures
Preliminary analyses are performed to obtain insight into the seismic response of subsystems supported on simple structures that yield during severe earthquake ground motions. Current...

Coupled Vertical-Rocking Response of Base-Isolated Structures
A base-isolated building can have a small horizontal eccentricity between the center of mass of the superstructure and the center of rigidity of the supporting bearings. The structure...

Techniques for Automating the Process of As-Built Reconciliation
The approach utilizes an electronic digital 'ruler' capable of measuring distances to 100 feet with a resolution of 1/100 of a foot. This ruler interfaces to...

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,...

A Computer Integrated Engineering System for Nuclear Plant Design
