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...

Hydraulic Representation of Flow Cross Sections
Herein, the writers will show that the conveyance of the channel section calculated by multiple section representations is never less than that by a single section representation. Also,...

Nonlinear Analysis of Uniformly Loaded Hexagonal Shells
Current core design for Liquid Metal Fast Breeder Reactors (LMFBR) consists of a honey comb array of subassembly ducts containing fuel elements. The subassembly duct is typically a long...

Frame Optimization Including Frequency Constraints
The minimum weight optimum design of planar frame structures subject to frequency (or buckling) constraints, stress constraints, and member sizing constraints is covered by the finite...

Inelastic Behavior of Wood Beam-Columns
The pattern of stress distribution at failure in the critical cross-sectional area is mathmatically formulated on the basis of the actual stress-strain diagrams. The validity of the theoretical...

Torsional Flutter of Rectangular Prisms
Prismatic bar models tested are of rectangular cross section and are provided with different side ratios (depth/height) of 1, 2, 4, and 5. The position of axis of rotation of the model,...

Boundary Shear in Channel with Flood Plain
Shear stress distributions were measured around the periphery of a channel of complex cross section using Preston tube. The complex section consists of a deep channel and a flood plain....

Creep and Shrinkage in Reactor Containment Shells
The nonuniformity of creep and shrinkage caused by drying, and to a lesser extent by temperature gradients, causes significant self-straining in containment shells. This condition can...

Curvilinearly Corrugated Plates in Shear
Theoretical numerical data are presented for: (1) The in-plane shear stiffness of corrugated plates with discrete attachments to framing members at the ends of the corrugations; and (2)...

Yaw Effects on Galloping Instability
Quasisteady theory of galloping oscillations of slender prismatic structures, such as transmission lines, stay cables, etc. is extended to cover flows approaching at a yaw angle. From...

Continuum Method for Overall Stability of Tall Asymmetric Buildings
A solution for the buckling loads of asymmetric tall buildings with uniform cross section is presented, using a three-dimensional continuum model and including the effects due to normal...

Pipeline Bridge Uses Timber Arches
An arch bridge is utilized for the purpose of providing a river crossing for a water supply pipe. Tidal influence, an unfavorable riverbed situation complicated by estuarial and other...

Critical-Flow Flumes with Complex Cross Section

Economic Shape of Trapezoidal Open Channel Sections with Freeboard
It can be proved mathematically that the maximum flow by the Manning formula is an open channel of trapezoidal cross section of fixed side slopes and with a fixed freeboard occurs r=(5/2)fx/q,...

Moment-Curvature for Elastoplastic Beams
To determine the deflected line of a beam, it is necessary to know the relationship between the bending moment and the curvature. It the cross section is defined, the desire relationship...

Elastic Stability Plates Subject to Elastic Constraints
With the continuing effort to reduce weight in engineering structures, load-carrying members are being made more slender and of smaller total cross-sectional area by the application of...

Critical Oxygen Deficit for Bank Outfall
A two-dimensional equation for the mass balance of dissolved oxygen (DO) is integrated numerically to obtain the distribution of oxygen deficit resulting from a bank outfall of BOD in...

Speed of Ships in Restricted Navigation Channels
Ship model experiments confirm that orthodox screw-driven craft attain an apparent maximum or barrier speed in navigation channels of restricted width and depth, irrespective of available...

Investigation of Dynamic Taping
The preferred time for reading tape length when using dynamic taping is suggested, differing from the one previously proposed. The dynamic taping technique has been suggested as a method...
