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...

Recent Lifeline Seismic Risk Studies
This monograph is a collection of four papers presented at the 1990 Annual Civil Engineering Convention and Exposition in San Francisco, California. The papers summarize seismic loss and...

Structures Congress Abstracts 1990
Abstract only. The following themes are included: Rehabilitation and future challenges, Bridges, Earthquake engineering, Dynamic loads on structures, Metals and composite construction,...

Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...

Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...

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...

An Education in Tunneling
A senior civil engineer and winner of the 1988 Martin Kapp Foundation Engineering Award describes the evolution of U.S. tunneling technology and practice. Trained as a structural engineer,...

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...

Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...

New Concepts in Transmission Line Design
Committees of the American Society of Civil Engineers have been in the forefront on updating design guides to address improved procedures for conventional latticed towers, formed-plate...

Longitudinal Impact Loading of Transmission Towers
A scale model has been developed to study a containment failure design concept for longitudinal (along the direction of the conductor) impact loading of electrical transmission structures....

Variation in Design Practice for Lattice Towers
The design and analysis procedures employed for lattice transmission towers vary among countries, companies, and designers. This variation in design practice affects the relative reliability...

Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Structural Computing in Engineering Practice
Since its emergence some thirty years ago, finite element technology has penetrated a significant part of the structural engineering profession. It serves as a most graphic illustration...

Representation of Strategic Choices in Structural Modeling
A major concern in structural modeling is the proper choice of tools to achieve stated objectives. Problem statements in structural analysis and design are usually made in fairly abstract...

Experiments on Active Structural Control Under Seismic Loads
Two control systems, an active tendon system and an active mass damper system are selected for study for possible real structural implementation. Presented in this paper are simulation...

Frequency Response Design of Controlled Structures
The installation of optimal control systems has been shown to be effective in reducing the vibration responses of structures. In addition to the effectiveness, there are many factors that...

Total Optimization of Truss Considering Shape, Material and Sizing Variables
A total optimum design method is developed for truss structures in which the shape of the structure, discrete material kinds and cross-sectional areas of member elements are optimized...
