Design and Performance Requirements for Surface Facilities of a High Level Nuclear Waste Repository
This paper describes three important steps in the design process of repository surface facilities: (1) Establishing performance requirements and risk levels, (2) translating performance...
Guidelines for the Development of Natural Phenomena Hazards Design Criteria for Surface Facilities
This paper discusses the rationale behind the guidelines, criteria, and methodologies that are currently used for natural phenomena hazard design and evaluation of DOE nuclear and non-nuclear...
Scoping the Monitoring Instrumentation to Meet Repository Design and Construction Needs
This paper discusses categories of instruments that are available and recommended for consideration to monitor the engineering performance and interactions of the geologic media, groundwater,...
Engineering: Environmental vs. Developmental Goals
The 1992 winner of the Daniel W. Mead Student Paper competition explores the potential conflict for engineers, between environmental and developmental goals. Noting a dictionary definition...
Banking on a Bridge
Completing the geotechnical design for the approach embankments and foundations for the Charter Oak Bridge, which crosses the Connecticut River between Hartford and East Hartford, Conn.,...
Seismic Design Criteria for Transporation Structures
Presented is a discussion focusing on two critical issues which must be resolved when setting seismic design criteria for important transportation structures such as those supporting elevated...
Controlling the Seismic Behavior of Precast Concrete
Precast concrete has, through the years the years, acquired a bad reputation insofar as its ability to withstand earthquake is concerned. This reputation, though reasonably based, is not...
Analytical Platform Development for Precast Structural Systems
The multi-investigator PRESS (Precast Seismic Structural Systems) research project requires an analysis tool that can be used to perform nonlinear seismic analyses of a wide variety of...
Design Criteria for Seismic Connections in Precast Concrete
The seismic behavior of precast concrete is contrasted with that of cast-in-place and the conditions that precast must satisfy are reviewed. Design criteria and possible strategies for...
Ductile Connections for Precast Concrete Frame Systems
This paper describes a research program to investigate the behavior of ductile connections between precast beam-column elements. The objectives of the program are to provide rational design...
Seismic Performance Behavior of Precast Concrete Beam-Column Joints
The experimental test program being conducted at the National Institute of Standards and Technology on 1/3-scale model precast concrete beam-to-column connections is summarized. The objective...
Seismic Response of Average High-Rise Building Structions in Japan
Dynamic characteristic models, representing average high-rise building structures in Japan, have been established through the regression analyses utilizing review documents of seismic...
Simulated Earthquake Ground Motions for Design Purpose
In this paper, firstly, it was clarified that there is a case where in the long-period range there is seen a tendency to follow the ?+-2$/ model approximately while in the short-period...
Safety Enhancement of Bridges with Seismic Isolation Bearings
This paper summarizes the experimental and analytical studies done at Dept. of Civil Eng., Kyoto Univ., on application of base isolation bearings to highway bridges and the Menshin (base...
Buildings with Response Control Systems in Japan
Today, there are more than 30 buildings with response control systems. The system is defined as one that suppresses or controls the response to the vibrational motion input of the buildings,...
Rocking Behavior and Retrofit of Tall Bridge Piers
In the aftermath of the damage to the San Francisco Oakland Bay bridge, due to the 1989 earthquake, a comprehensive study of the seismic behavior of the bridge was undertaken. This paper...
Assessment and Testing of Column Lap Splices for the Santa Monica Viaduct Retrofit
This paper describes assessment and the full-scale test of a 3 ft. (914 mm) dia. column containing #11 (34.9 mm dia.) reinforcing steel lap-spliced in the critical region. The column modelled...
Seismic Performance and Retrofit of the Golden Gate Bridge
The Golden Gate Bridge has served for over fifty years as a vital transportation link connecting San Francisco with the area to the north. The Bridge is owned, operated, and maintained...
Seismic Design Considerations for Uplifted Tanks
An evaluation of the most commonly used seismic design procedures for unanchored tanks is presented. It is noted that current standards are inconsistent in predicting the behavior of unanchored...
Input for Seismic Design of Major Structures
Effective seismic input considering the soil-structure interaction or soil-pile-structure interaction is presented. This approach takes the seismic wave as primitive input and considers...
