Building Blocks for the Future
In the near term, advanced, conventional materials�namely higher-strength steel and concrete�will dominate infrastructure rehab. New steels of higher strengths and toughness are increasingly...
Cleaning Up: The Second Decade
Endless media coverage and a high level of public anxiety make it seem as though the U.S. has been attempting to clean toxic waste sites for decades. In fact, the 1980s were our first...
Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...
Structural Details: Is Anything Missing?
While actual failure of a structure is uncommon, many projects have less publicized, detailing-related difficulties involving rework, changes, clarifications, and increased costs. If the...
Industry Faces the Parking Problem
Parking structures are deteriorating; no land is available for new facilities; and employees have no other options for parking. The situation is a serious one, verging on disaster for...
Anchoring a Dam
To comply with Federal Energy Regulatory Commission requirements with regard to stability under a postulated Probable Maximum Flood, an extensive foundation investigation and stability...
Retaining Forest Roads
The U.S. Department of Agriculture, Forest Service, manages a vast system of roads which provide access to America's national forests. More than 250,000 miles of roads exist...

Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...
Behavior of Structures During Earthquakes
Originally published in: Journal of Engineering Mechanics Division, ASCE, EM4, October 1959, pp. 109-129...
Development of Hydraulic Structures
The Bureau of Reclamation was established in 1902. Since that time, Reclamation has constructed more than 220 dams. Each dam, depending on its function, has two or more principal hydraulic...
The Colossus Superstructure
This chapter explores the structural elements of the Colossus....
Wind Bracing
This chapter discusses the structural design of the bridge with regards to wind forces....
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Building Moon Bases
It is widely accepted that the U.S. will begin to build a base on the moon at the turn of the century, and much of the design work has already been done. Based on papers presented at Space...
Fabric Meets Cable
The newest generation of fabric-roofed stadiums are cable domes designed by David H. Geiger of Geiger Gossen Hamilton Liao Engineers, New York City. He also uses the term tensegrity coined...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
High Tech on Campus
Hannan Hall, the new laboratory building at The Catholic University of America, has a structure entirely made up of precast concrete panels and 24 in. deep double tees. The loadbearing...
Analyzing in 3D
Suggestions for modeling and evaluating three-dimensional (3D) structures are presented. These suggestions are based on the authors' sixteen years of day to day involvement...
Floating Membrane Supertankers: Are They Feasible?
Optimal shapes of long cylindrical membrane containers are obtained by restricting the circumferential membrane stress to be tensile and constant throughout the tanker. Optimality is achieved...
Some General Remarks on the Structural Behavior and Load-Extension Characteristics of Coated Fabrics with Special Reference to PTFE-Coated Glass-Fiber Fabric
The understanding of fabric behavior, and of coated fabrics in particular, is essential for the design and analysis of fabric structures. Although many research papers have been published...
