Transverse Mixing in Partially Stratified Flow
The paper reports the results of a laboratory study on the rate of transverse mixing in oscillatory estuary-type flow with density gradients typical of those found in real estuaries. Two...

ASMUG - Simulation Model of Urban Growth
While differing substantially in structure, past attempts at mathematical models of urban development have generally had certain characteristics in common. They have usually: (1)Operated...

Fault Movement Effects on Buried Oil Pipeline
In earthquake zones pipeline crossings of major active faults are often unavoidable, and movements of these faults can have serious consequences for the pipeline. The ability of a large...

Finite Element Approach to Waves Due to Landslides
The finite element method based on the weighted residuals principle is used for the description of the generation and the unidirectional propagation of waves in a channel due to the temporal...

Plastic Analysis under Combined Stresses
Based on matrix algebra, decomposition, and linear programming techniques, a general mathematical model is developed for rigid-plastic analysis of discrete elements and structures under...

Hydrodynamic Pressure in Semicylindrical Reservoir
Solutions are presented for modal analysis of hydrodynamic pressures generated by the three translational seismic components — longitudinal, vertical, and transverse — on a dam limiting...

Biaxial Interaction Exponent for Concrete Columns
A general method of computing the biaxial interaction exponent directly, for rectangular reinforced concrete columns is presented. The method takes into account all variables involved...

Static Behavior of Wire Rope
A method for determing the static response of a wire rope with a cross section consisting of wire strands has been developed. The method is an extension of previous work and requires the...

Channel Siltation Determined with Side-Scan Radar
Of the new electronic means to measure water depth, side-scan sonar is unusual in that it gives not just a cross-section of the bottom but a semi-3-D picture of the bottom surface. Experienced...

Columns Braced in Nonprincipal Directions
This note is concerned with the flexural buckling of a prismatic column having a single brace not parallel to either of the principal axes of the column cross section. One way is which...

Complex Infinite Beams on Elastic Foundation
Simple infinite beams on an elastic foundation have presented few problems, in fact they are usually easier to solve than beams of finite length. For some time it has been possible to...

Rationalizations of Sections Properties Tables
Round-off to nearest (and usually larger) available standard cross section involves a component of waste in design that, together with other relevant costs, should be minimum. Commonly...

Method of Developing Optimum Tolerances
Standards should optimize for society. This is approximately accomplished by minimizing the sum of expected present values of initial cost and losses due to failure (entrance into limit...

End Effects in Long Curved Beam
Eigenfunction solutions of the biharmonic equation have been used to investigate the Saint-Venant boundary region in a long curved beam of rectangular cross section. The participation...

Longitudinal Dispersion Coefficients for Streams
A simplified method is presented to predict the longitudinal dispersion coefficient for natural streams. A dimensionless parameter, β, which is the function of the shape of the channel...

Elastic Stability of Polygon Folded Plate Columns
Using the techniques of discrete field analysis, the stability equation is obtained in a form independent of the number of sides in the polygon cross section. The stability equation was...

Inelastic Cycles of Axially Loaded Steel Members
Sixteen fixed-ended steel bars of rectangular cross section 1/2 in. x 1 (12.7 x 25.4-mm) and (12.7-mmand of various lengths were tested under 25.4-mm) nder static and dynamic loads to...

Comparison of Single-Point Injections in Pipe Flow
For applications such as using tracer techniques for discharge measurements in pipes or using a segment of a pipe as a mixing chamber, it is desirable to know the rate at which the concentration...

Axial Hysteretic Behavior of Steel Members
A procedure for predicting the force-deformation behavior of axially-loaded members with intermediate slenderness ratios is developed for use in computer-aided inelastic dynamic analyses...

Influence of Canyon on Soil-Structure Interaction
The exact solution of the dynamic response of a shear wall on an elastic half space with a canyon having semicircular cross section is presented for excitation by plane SH-waves. It is...
