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...
Cables and Flexible Pipes in Contact with Sea Floor
Flexible offshore systems can be analyzed by a number of different techniques. The techniques described herein fall in the general category of finite element methods. Special cable elements...
An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...
Transmission Line Structure Loading
This paper outlines specific procedures for determining loads on transmission line structure systems that can be used in the reliability based design or assessment of components of these...
Improved Techniques for Assessing Structures
The Electric Power Research Institute (EPRI) has specially designed and equipped the tower testing station located within their Transmission Line Mechanical Research Center (TLMRC) near...
Assessment of Conductors
This paper deals with the mechanical integrity of conductors after several years in service and discusses current innovative conductor designs which benefit the structural designer working...
