California Department of Transportation Seismic Retrofit Program: The Prioritization and Screening Process
Following the October 17, 1989 Loma Prieta Earthquake, the California Department of Transportation was designated as the lead agency to seismically retrofit all 23000+ public owned bridges...
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...
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...
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...
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...

Working Breakwaters
Along the Virginia portion of the Chesapeake Bay, shoreline erosion has erased about 40,000 acres of land since 1850. Now a series of headland breakwater systems stems erosion up and down...
Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...
Manhole Rehabilitation
Manholes are frequently the forgotten element in infrastructure renewal. When they aren't properly maintained they allow excess water into the sewer system, and structural...
