Flow and Sediment Transport in Curved Channels with Nonuniform Bed Material
Described is a scheme for controlling the exchange of grain sizes between bed and bed load in a curved alluvial channel. The scheme is an integral part of a model for simulating spatial...
Laboratory Model Studies of Flood Wave Propagation
Laboratory investigations of unsteady free-surface flow with various combinations of channel and flood conditions were performed. A 72 ft (21. 9 m) long tilting flume was modified to make...
Analysis of Freshwater Distribution System at the Long Beach Naval Complex
This account of the evaluation of freshwater pipelines at California's Long Beach Naval Complex discusses current methods for assessing the condition of damaged water lines....
Reviewing for Potential Failure
The key to preventing structural failures is to examines them and develop systematic techniques for avoidance. One, called contingency analysis, starts with a what if process to decide...
Available Compaction Equipment
When discussing available compaction equipment we must keep in mind the purpose of compaction. Compaction is the art of artificially increasing the density or increasing the unit weight...
Production Analysis of the Cat 245 Hydraulic Hoe
The productivity of two Caterpillar model 245 hydraulic backhoe excavators was analyzed during their use on a highway construction project in September 1983. The hoes were working in a...
Use of Nondestructive Testing in Rehabilitation of Wood Cooling Towers
State-of-the-art nondestructive evaluation (NDE) techniques, destructive testing, structural analysis, degradation rate models and statistical analysis are combined to optimize a major...
Nondestructive Evaluation of Timber Bridge Piles
A nondestructive technique for the determination of the in-place strength of timber bridge piling is presented herein. The testing technique is the ultrasonic wave propagation method in...
Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...
ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...
Evaluation of the Seismic Performance of Buildings
The aim of the paper is to present the different existing methodologies available for the assessment of seismic damage to buildings. The approach aims towards the development of a mini-computer...
Techniques for Estimating Earthquake Probable Loss for Buildings and Contents
The probable maximum loss (PML) is useful for quantifing the seismic risk exposure of a facility and for rational decision making regarding earthquake insurance and seismic strengthening...
Rapid Identification of High Risk Building in Seismic Regions Using Expert Systems
Seismic risk evaluation is a complex problem because it involves many factors such as ground motion, ground failure potential and structural performance with great uncertainties. Many...
Seismic Risk Analysis of a Multi-Site Portfolio of Buildings
A discussion of a methodology that permits the assessment of the seismic risk associated with a group of buildings and incorporates relevant aspects of seismic hazard assessment including...
Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
