# 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...*

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...*

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...*

Ethics: Wisconsin Section Sparks Timely Discussion

*Eight case studies of ethical questions were debated in an audience participation panel format, at the 1975 Wisconsin Section ASCE Annual Meeting. The program was judged successful for...*

Torsion and Flexure of Closed Thin-Walled Beams

*In Ref. 2, a method of determining the stress and deformation of curved thin-walled beams having general loading and geometry was presented. This method considered the effects of warping...*
