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...
Applications of Strain and Deflection Monitoring Systems for Post-Earthquake Safety and Usability of Lifelines
The paper proposes and discusses a variety of strain and deflection monitoring devices and systems for post-earthquake safety evaluation of lifelines. There is clearly a need, both in...
Evaluation of Techniques for the Seismic Modeling of Elevated Freeway Bridges
Following the October 1989 Loma Prieta earthquake in Northern California, a number of seismic parametric studies were performed for both two-level elevated freeways and single-column bridge...
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...
Seismic Analysis and Design of RC Lifelines
This paper describes the general approach for analyzing a soil-reinforced concrete lifeline system subjected to seismic loading, and the development and importance of transfer functions...
Simplified Uplift Analysis of Unanchored Cylindrical Tanks
Seismic tank damage has been reported in almost every major earthquake in the past, sometimes with serious environmental ramifications, thus raising concerns about the safety of these...
Effects of Cracking on Damping of Concrete Dams
A methodology is presented for dynamic analysis of concrete dams that considers the nonlinear stiffness and energy absorption effects of cracking. A cracking-consistent damping model is...
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,...
Bridge Damage Review?Loma Prieta Earthquake
The Loma Prieta Earthquake that struck the San Francisco Bay Area on October 17, 1989 caused varying degrees of damage on highway bridges. Within a few hours of the event CALTRANS had...
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...
Traffic Reporter is a PC-based graphical, interactive, traveler information system being developed to meet the informational needs of Seattle-area commuters. The goal of Traffic Reporter...
A Dynamic Modelling Framework of Real-Time Guidance Systems in General Urban Traffic Networks
There is considerable interest around the world in developing and implementing realtime driver information and/or guidance systems to reduce congestion in the urban traffic networks. However...
Encouraging Tourism and Access Through Recreational Marina/Waterfront Design
Encouraging tourism and access through the development of recreational marina facilities challenges a community and marina designer to create a Master Plan which incorporates a wide range...
Structural Investigation of Marina Del Rey Seawall
The Marina del Rey Seawall was constructed by various contractors between 1959 and 1961. It is composed of 660 panels totaling 39,600 linear feet. The seawall configuration is a type normally...
Case History of the Point Roberts Marina
This paper presents a fifteen year history of the design performance of the Point Roberts Marina. The 1,000 berth small craft harbor is located on the Strait of Georgia, immediately north...
Innovative Breakwater Designs on the Great Lakes
Extensive investigations have recently been undertaken to support the development of rubblemound breakwater designs for new marinas at Kenosha and Sheboygan, WI, both located on the west...
Reef Breakwater Design for Lake Michigan Marina
An innovative breakwater concept consisting of a conventional breakwater and a submerged-reef breakwater operating in tandem has been designed for the southern end of Lake Michigan. The...
