Diffuser Performance for Draft Tube Applications
Available information on diffuser performance is summarized in relation to draft tube applications. This paper is particularly directed at the implications of basic research with these...
Characterization of the Dalton Highway Foundation Soils
A case study is presented of the landform-based probabilistic-statistical route geotechnical characterization of natural foundation soils along the Dalton Highway. Landforms were mapped...
Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...
Measuring Dynamic Occupant Loads by Microcomputer
Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically...
Incorporating Uncertainty in a Dynamic Structural Analysis
A methodology has been developed and exercised for taking into account parametric uncertainties in a structural dynamics analysis and providing an approximation of the probability of response....
Failure Classifications
A detailed description of the failure classification with respect to the constructed facilities is presented. Author is of the opinion that most reports of failure even of an extensive...
Non-Freeway Programwide 3R Accident Analysis: New York
The New York Program for restoration, rehabilitation and resurfacing (3R's) has relied on broad scoped projects and case-by-case consideration of exceptions to design standards...
Sighting Safety
This paper examines the interrelation between drivers' visual needs and the road environment. Specific elements of visual limitation and drivers at greatest risk are identified....
Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...
Use of Vibration Tests to Determine Lateral Load Paths in Medium Rise Buildings
A structural system identification procedure is described in which an initial analytical model of a building is modified until it predicts accurately the mode shapes and natural frequencies...
On Reliability-Based Structural Optimization for Earthquakes
Previous studies of reliability-based structural optimization have been extended in order to investigate the applicability of the linear statistical model in cases where random parameters...
