Facility Accessibility Through Barrier-Free Design
This paper will outline the background, methodology and approval process used in developing national uniform design standards for barrier-free access to public boating and fishing facilities....

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,...

Influence of Rigidity of Soil Surrounding Shield Tunnel Upon Equivalent Rigidity of the Tunnel in Axial Direction
The purpose of this study is to investigate the interaction between ground surrounding a shield-driven tunnel and segments, especially their ring-joint portion. When a seismic force acts...

Performance of Liquid Storage Tanks during the 1989 Loma Prieta Earthquake
Utilities and industrial facilities in the strong shaking area of the 1989 Loma Prieta earthquake include a large inventory of tanks of all types. The earthquake induced a few incidents...

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 Design by Elastic Layer Theory
The U. S. Army Engineer Waterways Experiment Station has been developing methodology by which airport/airfield pavements can be designed based on elastic layered analysis for the Federal...

Pavement Design for the New Denver International Airport
Denver International Airport is the first new major U.S. airport in twenty years. Primary airfield elements in Phase I development include 5-12,000 foot runways and 1-16,000 foot runway,...

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...

Runway Roughness Measurement, Quantification and Application: The Boeing Approach
The measurement of runway roughness and the determination of the severity of runway roughness have long been the subject of nebulous discussion and esoteric description. By considering...

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...

Pavement Experiences Indicative of Needs to Consider Design and Specification Revisions
Recent experiences on two airfield paving projects have indicated some problem areas which may warrant further consideration in design manuals and specifications. 1. Construction of the...

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...

Aircraft Flexible Pavement Design in Australia
After World War Two, aircraft pavement design practice in Australia was largely developed from the work done by the U.S. Corps of Engineers. The C.B.R. pavement design method now differs...

DFW Concrete Block Pavement Taxiway Construction
The first concrete block pavement constructed on an airport in the United States was constructed at Dallas/Fort Worth International Airport during 1990. The use of concrete blocks on three...

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...

An Airfield Pavement Consultant System (AIRPACS) for Rehabilitation of Concrete Pavements
Airfield pavement knowledge captured by this research showed that knowledge-based techniques can be used to quickly select and design rehabilitation alternatives for a runway, taxiway...

Results of the 1989 ASCE Airfield Pavement Survey
In November of 1989, the American Society of Civil Engineers Airfield Pavement Committee sent out questionnaires to airfield pavement engineers across the country to assess the most recent...

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...

Aircraft/Pavement Interaction
An Integrated System
This proceedings, Aircraft/Pavement Interaction?An Integrated System, consists of papers presented at the specialty conference held in Kansas...
