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,...
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,...
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...
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...
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...
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...
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...
Retrofitting Fossil Plant Facilities Structural Perspectives
This publication, Retrofitting Fossil Plant Facilities: Structural Perspectives, was prepared by the Retrofit Task Committee of the Fossil Power Committee of the American Society of Civil...
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,...
Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...
Anchors in the Desert
The Southwest desert isn't usually thought of as a hotbed of seismic activity, but earthquakes have occurred there. And if Arizona's Stewart Mountain Dam, a double-curvature...
Wind-Induced Response of Torsionally Coupled Buildings
This paper summarizes the results of a comprehensive three-dimensional dynamic analysis of tall buildings subjected to fluctuating wind forces. Random vibration theory is used to relate...
Time Dependent Stochastic Characteristics of the Lateral Random Vibration of Tall Structures with Circular Cross-Section
From full scale measurement of the pressure field at three levels of a concrete chimney with 230 m height the lift coefficient is deduced and the lateral oscillation is investigated. The...
Optimal Distribution of Tuned Mass Dampers in Wind-Sensitive Structures
Modern high-rise buildings are susceptible to excessive accelerations at the upper floors in wind storms due to flexibility and low damping. In order to keep acceleration levels below...
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,...
