Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...
Pavement Materials for ASTOVL Aircraft Application
Jet blast impingement on concrete is a problem today and will worsen when the new vectored-thrust aircraft become operational. Ground erosion has already been observed under the auxiliary...
Modified Asphalt Binders for Military Airfield Pavements
This report documents a laboratory-based research effort to determine the effects of asphalt modifiers and alternate binders on asphalt airfield pavements. The modified binders were tested...
Concrete Mixture Evaluation and Acceptance for Air Field Pavements
Evaluation of the strength of portland cement concrete using flexural strength and compressive strength tests is examined. Problems with the use of flexural testing in the field are discussed...
Recycling Bituminous Runway Pavement into Aggregate Base Course
The paper discusses the development of recycling existing bituminous runway pavement by pulverizing into aggregate base course. To best explain the design, construction procedures and...
A Concrete Alternative to Runway Reconstruction
Faced with the prospects of losing commercial air service for up to two months, the Charleston County Aviation Authority, the Charleston Air Force Base and their engineers had to look...
Alternative Airfield Pavement Quality Control
In recent years, the cost of maintaining quality control during airfield construction projects has concerned airport operators and engineers alike. This paper addresses the possibilities...
Aircraft/Pavement Interaction
An Integrated System
This proceedings,
Guideline for Structural Condition Assessment of Existing Buildings
Changing economic conditions, concerns for historic preservation, emphasis on fully utilizing conveniently located structures, space shortages, and increasing cost of materials and products...
Waste to Energy? The Burning Question
For all their bad press, waste-to-energy plants actually provide a one-two environmental punch�they reduce garbage volume and provide alternative energy. But increasingly, state and local...
Fly Ash for Hire
Each year, roughly 15 million tons of ash created by U.S. coal-fired powerplants is recycled. Most is used in concrete and other construction materials, such as structural fill, but utilities,...
Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Reliability of Overhead Transmission Lines Subjected to Wind Action
The probability distribution of the strength of steel towers used in transmission lines, due to wind excitation, is evaluated on the basis of test results of 72 towers of various designs,...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
Seismic Response and Vulnerability of Water Delivery Systems
The response and vulnerability of straight segmented buried pipelines subject to seismic wave propagation are investigated in this paper. Seismic damage to buried pipelines is briefly...
Pipeline Field Experiment at Parkfield, CA
A field experiment designed to investigate the performance of buried pipelines at a fault crossing has been constructed near Parkfield, CA. The site was chosen to capitalize on the predicted...
Response Analysis of Crude Oil Transmission Systems
A preliminary analysis of the seismic response of continuous steel pipelines is presented. The Crude Oil Transmission System in the New Madrid Mo. area is choosen as an example. Assumptions...
Application of Physical Laws to Parameter Estimation for Probabilistic Models of Cumulative Damage
In this initial paper we will discuss the development of the application of physical laws to the modeling of cumulative damage and particular to crack growths. The basic assumptions due...
Damage Evolution in Reinforced Concrete Members Under Cyclic Loading
The paper presents a new damage indicator D, valid for reinforced concrete sections under cyclic loading. DQ, based on sectionally absorbed energies,...
