Small Dam Rehabs
The nation's 95,000 small dams face many of the same problems as the rest of its infrastructure, but with less money available for repair. In response, the owners of small...
Reduction of Head Losses in Tunnels by Means of Shotcrete
Head losses in blasted rock tunnels conveying water to hydropower stations often significantly reduces the energy production in the plant. Typical values on the head losses in tunnels...
A Review of Sprayed Concrete Linings Adopted at Dinorwig Power Station
Sprayed concrete was adopted extensively as one element of both temporary and permanent rock support during the construction of the 1800 MW Dinorwig underground power station in North...
Technical Evaluations Necessary for Determining Site Suitability for a High-Level Waste Repository
Congress, under the Nuclear Waste Policy Act of 1982, as amended, has charged the Department of Energy with the responsibility for safely and permanently disposing of high-level radioactive...
Design of Underground Repository Openings in Hard Rock to Accommodate Vibratory Ground Motions
A methodology and preliminary application for designing repository openings to withstand vibratory ground motions is presented. The methodology first establishes the design basis ground...
Block Dynamics Modeling in Support of Seismic Design
The behavior of an underground excavation is usually characterized by stresses and displacements which develop around the excavation as a result of prevailing field conditions. For conventional...
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...
Fire Endurance Model for a Metal-Plate-Connected Wood Truss
A numerical model has been developed for predicting the fire endurance of a single metal-plate-connected wood truss. Extensive component fire testing was conducted to develop the necessary...
Blast-Damaged Concrete Structures in Beirut
This paper describes the effect of blasting loads on structural members. It identifies predominant structural systems in war-damaged zones of Beirut and to explain typical damage mechanisms....
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...
Concrete Arch Bridges for Supporting Steel Conduits of Mingtan Pumped Storage Project
For the Mingtan Pumped Storage Project of an installed capacity of 1600 MW, two parallel waterways have been constructed for conveying flows between the upper reservoir and the lower reservoir...
Conceptual Design of a Monitoring System for Maglev Guideways
The state-of-the-art in nondestructive testing (NDT) technology has advanced significantly over the past fifteen years and has reached a stage where continuous monitoring of structures...
Reliability-Based Design of Transmission Towers Under Wind and Ice Loadings
This study suggests a practical but rational approach for the development of reliability-based LRFD criteria for transmission towers under wind and ice loadings in Korea. Based on available...
Finite Element Analysis of a Highway Bridge Hinge
A highway bridge hinge is a very important element in bridge design. It releases thermal stresses that may be developed in the superstructure or the substructure of a bridge. A common...
The Effect of Nonlinear Drag PSD on Fatigue of Compliant Offshore Structures
Structural fatigue damage induced by random ocean wave loading on a compliant type of offshore structure is considered. The nonlinear wave force is modeled by the Morison equation and...
Site Load Testing of Full Scale Composite Concrete Floors
The paper presents the results of a load test carried out in 1982 on a continuous reinforced concrete slab with a permanent shuttering consisting of compressed straw (Stramit) or cement...
Jatiluhur Dam: Problems and Rehabilitation
The Jatiluhur Dam in Indonesia, completed in 1965, is an innovative design consisting of rockfill embankment with a clay core and a vertical cylindrical Intake Spillway. Within the Intake...
Landslide Stabilisation at the Clyde Power Project, New Zealand
The Clyde Power Project is a hydro electric development on the Clutha River in the South Island of New Zealand. A wide range of stabilization measures have been used to treat several large...
Development of the Service & Maintenance Segment of the Transportation System
This paper discusses the progress to date in establishing the Service and Maintenance Segment of the Transportation System required to maintain the equipment required to transport spent...
Site and Facility Waste Transportation Planning Documents (SPDs): Status and Findings
