An analytical solution of the diffusion equation is used to determine criteria for use in river flow gaging by the dilution method. The method advanced in this paper allows the mixing...

Simulation in Watershed Planning
Hydrologic and hydraulic simulation is an effective technique in comprehensive watershed planning and in subsequent plan implementation. The need and rationale for simulation are considered,...

Solutions for Lateral Outflow in Perforated Conduits
Many applications in varied fields of engineering design require a uniform discharge in a perforated conduit. This paper gives general solutions for obtaining a uniform lateral outflow,...

Design Criteria for Submarine Pipeline Crossings
This laboratory investigation of pipeline crossings of alluvial streams shows that the rate of scour above the pipe varies as the dimensionless shear stress which is a function of the...

General Analysis of Nonplanar Coupled Shear Walls
A theory to analyze nonplanar coupled shear walls subjected to lateral loading is presented. The theory is applicable to a pair of shear walls of arbitrary cross-sectional shapes connected...

Finite Element Solution of Inelastic Beam Equations
Details are presented of a procedure for analyzing inelastic beam and beam column problems of arbitrary thin-walled open cross section, under the assumption of no strain reversal. The...

Lateral-Torsional Buckling of Built-Up Beam Columns
The lateral-torsional buckling strength of beam columns in both the elastic and the inelastic ranges is compared for (1) the influence of the residual stress patterns which are idealized...

Stress Analysis of Group of Interconnect Thin-Walled Cantilevers
The longitudinal axes of the cantilevers are assumed to be parallel while the main axes of the cross sections may have arbitrary directions. In addition to rigid diaphragms the flanges...

Absolute Minimum Weight Structures by Dynamic Programming
The structures considered herein are assumed to subject to fixed loads and design based on flexure. Furthermore, it is assumed that the cross-sectional area is proportional to the absolute...

Railroad Crossings at Berwick Bay
Modifications are made to a main-line single track railroad draw bridge across a much used wateway connecting the industrial Gulf Coast with the areas served by the Mississippi River....

Structural Designs for Bounds on Dynamic Response
An upper bound on the displacement at a particular point on an elastic beam resulting from impulsive loading may be established. For a given volume of material in a beam of sandwich cross...

Tapered Cantilevers with Varying Distributed Loads
Many investigators have considered the problems of cantilever beams undergoing large deflections. Barton and Bisshopp and Drucker solved exactly a cantilever carrying a concentrated load...

Inelastic Buckling of Rings with Residual Stresses
Circular rings are commonly fabricated by cold rolling long straight bars of desired cross sections to the required radii and then completing them with a single butt weld. This process...

Cantilever Cylindrical Shells under Assumed Wind Pressures
A complete analysis is presented for the problem of cantilever cylindrical shells (clamped at the base and free at the top) subjected to wind pressures. Donnell's shell theory is employed....
