Seismic Considerations in Sealing a Potential High-Level Radioactive Waste Repository
The potential repository system is intended to isolate high-level radioactive waste at Yucca Mountain according to the performance objective - 10 CFR 60.112. One subsystem that may contribute...

Options for Dynamic Analyses of Underground Facilities
Continuum and discontinuum modeling techniques for conducting dynamic analysis of underground facilities of geologic repository are discussed. Compared with continuum analysis, the discontinuum...

Dynamic Response of Tunnels in Jointed Rocks
We describe the application of the Discrete Element Method (DEM) to the dynamic analysis of the response of tunnels in jointed rocks to earthquake loading. In situations where large motions...

Stress Wave Loading of a Tunnel: A Benchmark Study
Five different finite element or discrete element computer codes were used to solve a sequence of problems leading to the problem of stress-wave loading of a circular tunnel in a jointed...

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...

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...

Wind Engineering?Engineering for Wind Damage Mitigation
The establishment in 1970 of a new engineering discipline, wind engineering, was motivated by property damage caused by windstorms of 1970 known as the Lubbock Tornado and Hurricane Celia....

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...

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 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...

Inelastic Behavior and Seismic Design of a Highway Shield Tunnel
Nonlinear behavior of shield tunnels required for seismic design by means of Seismic Deformation Method is presented based on dynamic loading tests. Application of the test results to...

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 Collapse Assessment of Reinforced Concrete Building
In this paper collapse analysis of reinforced concrete frame structures with and without brick infilled walls under a severe earthquake is developed. Because the structural element in...

Nonlienar Seismic Response Analysis of Shanghai Yangpu Bridge
The Yangpu Bridge is a long-span composite cable-stayed Bridge in which the superstructures is designed as a floating system to withstand the strong earthquakes. The nonlinear seismic...

Study of Failures of Towers and Tall Buildings Under Wind Loading
In this paper, two kinds of wind-excited limit states on a tall structure are investigated and corresponding formulae for the limit wind pressures are presented. In solving the wind-excited...

Response of Base Isolated Buildings in Japan to Recent Earthquakes
On February 2nd in 1992, more than 20 base isolated buildings in Tokyo experienced an earthquake of JMA seismic intensity 5. In this event, many acceleration records of isolated buildings...

Building Separation Rules to Avoid Seismic Pounding
A method to estimate the required separation to preclude pounding between adjacent buildings is presented. It accounts for the effect of yielding on the vibration phase of adjacent buildings....
