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...

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,...

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,...

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...

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,...

Man-Induced Changes of Middle Mississippi River
The objectives of the 150 yrs of development along the Middle Mississippi River have been to provide flood protection to people and property on the flood plain and to provide a suitable...

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,...
