Reliability of Highway Bridge Columns Under Earthquake Loading
Seismic design procedure for highway bridges normally specify that any inelastic action be confined to the columns. Concrete bridge columns are usually designed to resist an elastic force...

Seismic Risk Assessments of Small Earth Dams
A procedure has been developed which attempts to assess the risk of damage or failure of small earth dams and embankments when subjected to seismic input motions. The procedure is based...

Seismic Vulnerability Assessment of Bridges on Earthquake Priority Routes in Western Kentucky
This paper discusses the current conditions of 203 bridges on the priority routes in Western Kentucky and their vulnerabilities to earthquakes. A span-loss type of bridge collapse due...

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...

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...

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,...

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...

Lateral Load Test on Driven Pile Footings
The October 17, 1989 Loma Prieta earthquake provided an ideal time and situation to perform for the first time, at no installation cost, a full scale lateral load test on a group of driven...

Load Sharing Benefits of Composite Pile Systems
The paper develops design techniques which will allow piled systems to be extended into more onerous operating conditions. In storm events marinas always develop failure mechanisms at...

Joint Spacing for Airfield Pavement
This paper looks at various factors affecting portland cement concrete(PCC) pavement cracking, with special emphasis on the effect of joint spacing on crack development. A rational approach...

The Effects of Runway Roughness on Aircraft Fatigue Life
A computer code developed within the Flight Dynamics Directorate of the Wright Laboratory was used to simulate the dynamic response of heavy aircraft operating on runways with various...

Asphaltic Concrete Performance Under High Pressure Tires
A study was conducted by the USAF Engineering and Services Laboratory to evaluate the rutting effects of high pressure tires on Marshall and gyratory designed pavements. Full scale pavement...

Performance of Airport PCC Pavements During Spring Thaw Periods
The portland cement concrete (PCC) pavements at two Wisconsin airports, Central Wisconsin Airport in Mosinee, and Outagamie County Airport in Appleton, were monitored during spring thaw...

Prediction of Airfield Pavement Responses Using Transfer Functions
A methodology is presented which will aid in the evaluation and maintenance of airfield pavements. Predictions of an airfield pavement's behavior to multiple types and magnitudes...

ACN-PCN Concepts for Airport Pavement Management
The aircraft classification number-pavement classification number (ACN-PCN) method is the standardized International Civil Aviation Organization (ICAO) method for reporting airport pavement...

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