Atmospheric Corrosion Resistance of Structural Steels
The main objective of this paper is to provide engineers with data on thickness loss of structural steel members resulting from corrosion. To this end, the writers have collected atmospheric...

Through-Thickness Properties of Column Flanges in Welded Moment Connections

Cure for Thinning Concrete
After placing 75% of the concrete liner for twin 4.6 km transit tunnels in Portland, Ore., engineers discovered areas of concrete that were thinner than the prescribed 305 mm thickness....

Effects of Reservoir Regulation on Ice Jam Thickness

Estimation of Residual Stresses in Thick Section Weldments

Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...

Appalachian Piedmont Regolith: Relations of Saprolite and Residual Soils to Rock-Type

Numerical Simulation for Determining Through-Thickness Material Properties of Anisotropic Plates

The Effects of High-Strength Steel in the Design of Steel Water Pipe

Thermal Cycling of Thin and Thick Ply Composites
An experimental study was conducted to determine the effects of ply thickness in composite laminates on thermally induced cracking and changes in the coefficient of thermal expansion (CTE)....

Estimation of the Thickness of Transition Zone in Concrete and Characteristics of Transition Zone in High-Strength Concrete

Effect of Roughness and Thickness of Biofilms on External Mass Transfer Resistance
The effect of roughness and thickness of biofilms on the dissolved oxygen (DO) concentration boundary layer thickness (DO CBLT) and the external mass transfer process in a biofilm system...

Single-Shell Shotcrete Method
On a 60-m-long test stretch in the course of the construction of the Munich Subway the single-shell jointless shotcrete method was employed. In this case the standard cross section of...

Using Neural Network to Identify Pavement Structure Based on Radar Output
Knowledge of asphaltic layer thickness and structure are important in many areas of pavement management. Accurate thickness and structure measurements are needed throughout the roadway...

Distribution of Flood Volumes Beyond Design Discharges
Quantitative prediction of flood volumes beyond design discharges is important for hydrologic design of river constructions, such as bridges and culverts, because these are the volumes...

Structural Design on Ductile Iron Pipe
The thickness class designation for Ductile Iron pipe has been changed to a pressure class designation in the 1991 revision of the C150/A21.50 ANSI standard. However, the same conservative...

Verification of the Princeton Transport Code (PTC)
The Princeton Transport Code (PTC) is a quasi-three dimensional groundwater flow and transport code. PTC is implemented using a splitting algorithm that allows the three-dimensional solution...

Analytical Prediction of Gasoline Thickness on the Water Table
With the increased use of immiscible fluid products such as gasoline, the threats to groundwater resources by hydrocarbon products are increasing. The success of recovery of the hydrocarbon...
