Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....

Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...

The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...

Approximate Preliminary Methods for Design of Lateral Load Resisting Systems in High Rise Buildings
A new group of optimization programs uses the speed and power of modern computers to eliminate the need for guessing preliminary sizes. Starting with any arbitrary sizes and a fixed geometry,...

Verification of Advanced Analysis Techniques
As a designer there is a concern over the complexity of analysis required by design specifications and building codes because it forces engineers into types of analysis for which many...

Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...

Verification of Approximate Methods of Structural Analysis
Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes'...

EPA's Development of Environmental Standards for High-Level and Transuranic Wastes
EPA is in the process of developing standards for the disposal of high-level and transuranic wastes. This development process is in response to a Court order that remanded standards that...

First Update to the U.S. Nuclear Regulatory Commission's Regulatory Strategy for the High-Level Waste Repository Program
The U.S. Nuclear Regulatory Commission (NRC) staff has updated its initial regulatory strategy for the High-Level Waste Repository Licensing Program. The update describes changes to the...

Regulatory Issues Impacting the U.S. High-Level Radioactive Waste Management Program
This paper addresses current key regulatory issues impacting the U.S. high-level radioactive waste management program. The following issues pertain to the licensing of a geologic repository:...

Safety Assessment of Radioactive Waste Disposal: A Priority Area for International Co-operation Within the OECD Nuclear Energy Agency
The OECD/NEA programme in the radioactive waste management area gives a high priority to long-term safety aspects of radioactive waste disposal practices. Overall aims of this part of...

OCRWM Transportation Technical Activities for 1998
The Office of Civilian Radioactive Waste Management is preparing for the transport of spend fuel by 1998 from commercial reactors to a monitored retrievable storage facility. The preparations...

Development of the ASME/NUPACK Code
A Committee has been active for 10 years to develop Code rules for the design, construction and in-service requirements of containment systems for nuclear spent fuel and high level radioactive...

Certifying the TN-BRP and TN-REG Transportable Storage Demonstration Casks
The U.S. Department of Energy (DOE) has obtained U.S. Nuclear Regulatory Commission (NRC) certification to transport two transportable storage casks for a demonstration project. Because...

Development of the GA-4 and GA-9 Legal Weight Truck Spent Fuel Shipping Casks
General Atomics (GA) is developing two legal-weight-truck spent-fuel shipping casks for transporting commercial reactor spent fuel. The GA-4 pressurized-water-reactor (PWR) and the GA-9...

High-Capacity, High-Strength Trailer Designs for the GA-4/GA-9 Casks
General Atomics (GA) is developing final designs for two dedicated legal-weight trailers to transport the GA-4 and GA-9 Spent-Fuel Casks. The basic designs for these high-capacity, high-strength...

Approach for Implementing Burnup Credit in High-Capacity Truck Casks
General Atomics (GA) will be submitting an application for certification to the U.S. Nuclear Regulatory Commission (NRC) for the GA-4 and GA-9 Casks in 1992. To maintain a capacity of...

Volcanic Episodes Near Yucca Mountain As Determined by Paleomagnetic Studies at Lathrop Wells, Crater Flat, and Sleeping Butte, Nevada
It has been suggested that mafic volcanism in the vicinity of Yucca Mountain, Nev., is both recent (20 ka) and a product of complex 'polycyclic' eruptions. This...

40Ar/?9Ar Laser Fusion and K-Ar Ages From Lathrop Wells, Nevada, and Cima, California: The Age of the Latest Volcanic Activity in the Yucca Mountain Area
K-Ar and 40Ar/39Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field,...

Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
