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...
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...

Airport Construction: The Japanese Way
Japan is spending tens of billions of dollars on airport projects domestically and abroad through their aid programs. Examples of construction at the New Osaka Airport (Kansai), Narita/Tokyo,...
Politics and Engineering
The 1991 winner of the Daniel W. Mead Student essay contest states that there is a stereotype of engineers as those who derive recreational pleasure from seeing who can do most with a...

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...
Man and Huge System Interaction
In many cases of disaster, the causes of failure of huge systems are frequently attributed to human error. However human is liable to error. To exclude human factor from a huge system...
Wind Loads on Large Broadcasting Antennas: Records and Elaborations
Alternative estimations of the 50-year gust winds from the data available in typical Italian sites of broadcasting antennas are summarized and compared with the design winds suggested...
A Methodology for Assessing the Reliability of TLP Tethers Under Maximum and Minimum Lifetime Loads
The Tension Leg Platform (TLP) is a large, floating offshore platform for producing oil and gas in deep water. The TLP is moored to the ocean floor by vertical tethers. Loads in the tethers...
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...
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...
Response Modification Factors for Buildings and Bridges
Response Modification Factors (RMF) are often used for the seismic design and the safety evaluation of buildings and bridges. The advantage of using RMF is to account for the nonlinear...
