Comparison of Correction Factor for Dispersion Coefficient Based on Entropy and Logarithmic Velocity Profiles
Recently, new velocity distribution equations have been developed by Chiu (1987, 1989) through the use of maximum entropy principle. A comparison will be made of the correction factor...
Application of the Ackers-White Procedure for Transport by Size Fractions and Testing in HEC-6
Modification of the Ackers-White method for the calculation of sediment transport by size fractions has led to a procedure which not only permits such calculations, but also increases...
Pressure and Stress Distributions Due to a Submerged Impinging Jet
This investigation examines the pressure and shear stress distribution at a smooth planar boundary in the impingement region of a submerged vertical jet in water. The mean pressure and...
Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...
Flow Field Near an Inland Navigation Tow
As a vessel moves through a body of water, disturbances are created in the form of altered water levels such as waves or drawdown and altered flow fields such as increased velocities and...
The Equivalence of Path and Node Methods for Water Distribution Network Analysis
This paper deals with the equivalence between commonly employed methods, path and node adjustment methods, for analyzing water distribution networks. The basic equations for steady-state...
Model Study to Design a Small Intake
A 1:4 scale model was used to design the make-up water intake structure for Burrillville Combined-Cycle Power Plant, Ocean State Power Project. The objective of the study was to assure...
Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...
Advances in Pipeline Materials
Pipelines transport water, storm run-off, process wastes, petroleum, natural gas, slurries, solids, sewage, steam and other fluids either by gravity or under pressure. Pipelines are also...
Wood Variability Effects in Structural Assessment
Engineers evaluating the load carrying capacities of in-service wood structures commonly determine the strength and stiffness properties of structural wood members by various assessment...
Bond Performance of Reinforcing Bars Embedded in Fiber Reinforced Concrete and Subjected to Monotonic and Cyclic Loads
The primary variables investigated were fiber content and loading history. The reinforcing bar size was ASTM #5. Steel fibers with hooked ends were used with four fiber contents, namely;...
Rate Effects on Fracture of Concrete
An analytical and experimental investigation of mode I (tensile and mixed mode (combined tensile and shear) fracture of concrete subjected to impact loading was conducted. The rate of...
Creep of Polycrystalline Ice
This paper discusses the extension of creep models for polycrystalline ice to include the effects of a non-monotonic loading history. Attention is focussed on cyclic loading since it is...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Durability of Fly Ash Concrete in the Marine Environment
This paper presents the experimental investigation of durability of air-entrained fly ash concrete in the marine environment. The findings indicate that the deterioration rate of durability...
Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...
Permeability Effects on the Sulfate Resistance of Concrete
A laboratory study was conducted to determine the effect of permeability on the sulfate resistance of concrete containing fly ash. Concrete specimens were moist cured for 7 and 100 days...
Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...
Early-Time Strength and Elastic Modulus of Concrete With High Proportions of Fly Ash
Compressive strength and elastic modulus data are presented for four concrete mixtures with ratios (by volume) of Class C fly ash to total cementitious materials (portland cement plus...
Parameter Study of Stresses in Mass Concrete Using Two Fly Ash Mixtures
Finite-element modeling of the incremental construction procedure for mass concrete structures has been used to study the effects of three mechanical properties on thermal stresses. Material...
