Seismic Condition Assessment of the San Francisco-Oakland Bay Bridge
The project summarized here was initiated at the University of California at Berkeley to study seismic behavior of the San Francisco-Oakland Bay Bridge and to develop recommendations for...
Report and Summary of ATC-31?Evaluation of the Performance of Seismically Retrofitted Buildings
Structural and damage data for seismically retrofitted buildings affected by the October 1, 1987 Whittier Narrows and October 17, 1989 Loma Prieta, California earthquakes were collected...
Recent Improvements in the LLNL PSHA Methodology
For the purpose of comparison, the LLNL PSHA methodology is defined as the 1989 version developed under contract for the NRC. Additional work on a series of subsequent projects for DOE...
A California Tower: Response to Seismic Forces
First Interstate World Center is a signature building for the city of Los Angeles. The granite clad tower with its serrated facade rises 1,018 ft. above street level. It is the tallest...
Structural Response Using Stiffness Decoupler
The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate...
Response of Equipment in Structures Supported on Resilient-Friction Base Isolators Subjected to Ground Motion
In this paper, the response of equipment in structures on a particular friction-type device, the resilient-friction base isolator, is examined. The R-FBI is composed of layers of Teflon...
Robust Control for Buildings Under Earthquake
Robust control techniques are applied to civil engineering structures subjected to earthquake excitation. Full state feedback and observer based control laws are used to reduce the response...
Hybrid Control of Seismic-Excited Bridge Structures Using Variable Dampers
A method of control for seismic-excited buildings or bridge structures using variable dampers is presented. The control method is based on the theory of variable structure system (VSS)...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
Dynamic Inelastic Analysis of Tall Buildings
Members with undesirably early formed plastic hinges as well as excessive conservatism introduced in the preliminary design of tall buildings can be identified by the behavior state study...
MASSPORT Modernization
Construction began last fall on the Massachusetts Port Authority (MASSPORT) upgrade of the 50-year-old Paul W. Conley Terminal in Boston. When completed in 1994, this timber-pile-supported...
U.S. Nuclear Regulatory Commission Staff Technical Position on Investigations to Identify Fault Displacement Hazards and Seismic Hazards at a Geologic Repository
This paper outlines the guidance provided to the U.S. Department of Energy by the Nuclear Regulatory Commission (NRC) staff in its Staff Technical Position (STP) on appropriate investigations...
An Assessment of Loading Capabilities of OCRWM Burnup Credit Casks
A new generation of spent fuel shipping casks are being developed for the Department of Energy (DOE) in support of transportation system development activities for the Civilian Radioactive...
Utility-DOE Interface Considerations of the Universal Container Systems Concept
This paper discusses the utility-DOE interface issues that must be addressed by the Department of Energy (DOE), the utility industry, and the Nuclear Regulatory Commission (NRC) prior...
A Concept to Combine DOE Waste Minimization Goals with Commercial Utility Needs for a Universal Container System for Spent Nuclear Fuel Storage, Transportation, and Disposal
The concept of storing, transporting, and disposing of spent fuel using a single package, which has obvious advantages, is put forward. It is coupled with using contaminated scrap metal...
A Galerkin Method for the Convection?Diffusion Equation Using Asymmetric Weighting Functions
A variation of the Petrov-Galerkin method of solution of a partial differential equation is presented in which the weight function applied to the time derivative term of a one-dimensional...
A Homogeneous Equilibrium Model for Analysis of Spent Fuel Shipping Containers
Transportation of nuclear spent fuel is inevitable over the coming years. However, in order to ensure the safety of such transport, computational models must be established, which are...

A Computational Method for Acquiring Response and Ground Motion from Accelerogram on the Base of Structure
This paper describes computational formulation of vibratory equations for acquiring response and input ground motion from accelerogram on the base of long structure with flexible slab....
Lifelike Model
Data from about 400 structures in the San Francisco Bay Area were recorded during the 7.1 Richter-scale Loma Prieta quake. Among these structures was a 49-story office tower in downtown...
