Principles of Graphical Gradually Varied Flow Model
Any gradually varied flow computation requires the solution of the energy and continuity equations. To this end, many techniques are available. For prismatic channels, the Direct Step...

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...

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...

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...

Beam Analog for Plate Elements
A beam-analog to continuously attached elements has been established as a method for the analysis of a continuum. Although the analog grid is composed only of orthogonally connected beams,...

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...

Earthwork Volumes by Contour Method
A new method for the computation of earthwork volumes in massive hillside grading projects is developed which increases the accuracy and vastly reduces the time and cost of calculations....

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...

Buckling of Axially Loaded Open Shells
This paper describes an experimental investigation of the buckling behavior of axially-loaded thin open cylindrical shells. The results of experiments with 36 aluminum shell specimens...

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...

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...

Experimental Investigation of Flow Over Side Weirs
Observations at numerous cross sections in a side weir channel showed that the total energy of flow decreases substantially along the channel, contrary to the assumption that has frequently...

Hydraulics of Surface Buoyant Jet
The spreading of a jet discharge horizontally at the surface of a quiescent receiving water of slightly larger density is investigated, assuming that the bulk Richardson number is moderate....

Ferrocement Load-Bearing Wall Elements
Some laboratory test results on ferrocement load-bearing wall elements of undulating cross section are presented. Slenderness ratio of the element, amount of mesh, and mild steel reinforcement...
