Telecommunications Facilities Earthquake Readiness Since San Fernando
The vertical rack architecture of telecommunication offices showed some weaknesses during the San Fernando earthquake in 1970. Efforts have been made since then to improve performance...

Seismic Design Criteria for Transportation Structures
Seismic criteria for the design of transportation stuctures have evolved slowly since their inception in the early 1940s. Although seismic design criteria are far more sophisticated than...

Understanding the Earthquake Environment, Corporate Strategies
Corporations should understand the impact that earthquakes may have on their ability to function. Some earthquake related issues which face a corporation are: earthquake design levels...

Stochastic Responses of Lifeline Systems Under Seismic Excitations
A wave superposition model is proposed to predict the field motion on the basis of the seismic records obtained from a strong motion array. By assuming the ground motion to be a homogeneous...

Elevated Water Tank Inelastic Seismic Analysis
In 1988, the Seattle Water Department hired CYGNA, a consulting firm, to assess the seismic reliability of their water system, since major earthquakes can occur in the area. Their study...

Collapse of the Cypress Street Viaduct
This paper is being presented by the Division of Structures, Post EarthQuake Investigation Team (PEQIT) on the collapse of the Cypress Street Viaduct in the City of Oakland, California,...

Lessons Not Learned from the Catastrophic Collapse of Highway Structures in the 1989 Loma Prieta Earthquake
Most of the damage sustained from the 1989 Loma Prieta Earthquake in Northern California was not a surprise to civil engineers and knowledgeable building officials. As early as the 1900s,...

Performance of Unreinforced Masonry Buildings During the Newcastle Earthquake, Australia
On December 28, 1989, an earthquake of Richter magnitude 5.6 shook the city of Newcastle. Newcastle is situated on the east coast of Australia only 100km north of Sydney. Eleven deaths...

Viscoelastomeric Connections in Seismic Structures
Nonlinear Kelvin and Maxwell impedances connect lumped masses to form arbitrary networks. Viscoelastomer-steel composite moment connections are modeled similarly, using auxiliary masses,...

Geotechnical Engineering Congress?1991
This proceedings, Geotechnical Engineering Congress 1991, consists of papers presented at the Geotechnical Congress held in Boulder, Colorado...

Guidelines for Electrical Transmission Line Structural Loading
This manual presents detailed guidelines and procedures for developing transmission line structure loads. It is divided into four sections. The first section is concerned with the load/strength...

Specification for the Design of Cold-Formed Stainless Steel Structural Members
ASCE's standard Specification for the Design of Cold-Formed Stainless Steel Structural Members (ASCE 8-90) provides design criteria...

Freudenthal Lecture Developments in Structural Reliability
Rather than reviewing the details of developments in structural reliability theory and its implementation over the last few decades, more recent and more relevant reliability issues are...

Loading Uncertainties in Extreme Waves
Uncertainties associated with extreme base shear forces and extreme overturning moments are estimated for an idealized eight-legged jacket platform. The structure is assumed to respond...

Probabilistic Evaluation of the Performance of Axially Loaded Bored Piles
Probabilistic evaluation of single slender elastic elements, bored piles, in a multi-layered soil system without noticeable displacement of the soils are considered. The numerical analyses...

Development of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base, which is still growing, currently contains information...

Graphic Demonstration of Seismic Hazards Data Base
A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base presently holds five categories of data, the largest of...

Global Damage Indices and Nonlinear Structural Response
Damage indices based on equivalent linear parameters have been proposed for the analysis of global seismic damage. The analysis of shaking table experiments and strong motion records has...

Simple Damage Predictors for Large-Scale Seismic Risk Mapping
Although it is now recognized that there is a risk of moderate seismic activity in the Eastern United States, many existing buildings were not designed for earthquake forces. To evaluate...

Seismic Fragility Analysis of Shear Wall Structures
This paper presents an analytical method to generate seismic fragility curves for shear wall structures. Uncertainties in earthquake motion and structure are quantified by evaluating uncertainties...
