Reliability Study of Randomly Imperfect Beam-Columns
In this study, the effect of random initial geometric imperfections was treated as a set of equivalent random initial forces. This concept enables the direct employment of existing stochastic...

Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...

Friction Factor and Patterns in Armor Coats
Recent observations of friction factors at armor coat forming discharges suggest the presence of distinct geometric patterns in the locations of the coarsest grains in armor coats. A statistical...

Two recent publications have reported the development of the Cornell Mixing Zone Expert System (CORMIX) for the analysis, prediction and design of aqueous toxic or conventional pollutant...

Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...

Current Status of Research and Implementation
A review of the effectiveness of roadway safety measures to reduce traffic accidents is given. This paper attempts to discuss in detail the current status of safety-related knowledge and...

Safety and Operations Related to Geometrics for 21st Century Highways
Highways designed for the next century must reflect the knowledge gained from research on safety and operations conducted over the last 20 years. Assuming that recent trends toward emphasis...

Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...

Reliability of Geometrically Nonlinear Structures
A procedure for first- and second-order, finite-element reliability analysis of geometrically nonlinear structures under static loads is presented. Structures are either linear or nonlinear...

Some basic statistical data covering geometrical and energy parameters for Francis turbine and Pump-turbine units are presented. These data are further compared as specific ratios for...

Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...

Model Study to Locate Aerators in Tunnel Spillways
A model study to locate, in an optimum way, aerators in tunnel spillways is presented. A Froude half model, scale 1:30, was used. The flow geometry, the air discharge sucked by the aerators...

Embankment-Dam Breach Parameters
The study used data from 43 embankment-dam failures to develop equations that predict breach formation model parameters. These data include the failure mode, embankment characteristics,...

Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....

Flutter Derivatives from 14 Generic Deck Sections
The results of a series of wind-tunnel bridge-deck section-model experiments are discussed. Fourteen section models, seven with H-shaped cross-sections and seven with rectangular cross-sections,...

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...
