Lowest Natural Frequency of Clamped Parabolic Arcs

*An analysis is made of finding the lowest natural frequency of a clamped parabolic arc with a variable section including the effect of the cross section and constant section....*

Free-Vortex Theory Applied to Free Overfalls

*When the flow from an open channel is discharged freely into the air, the depth at the brink can be often closely correlated with the flow rate. Free-vortex velocity distribution and curvature...*

Expandable Tip Piling

*The problems associated with the use of piles in low strength clay soils are well recognized and have been extensively studied. The purpose herein is to set forth a simple and economical...*

Siphons: Some Scale-Effects in Models

*A simple design of storm-overflow siphon for the city of Liverpool, England, has been tested in the laboratory at scales from 1/3 to 1/80. In this way, the effect of the absolute size...*

Drag or Along-Wind Response of Slender Structures

*Theoretical approaches to the evaluation of the response of slender structures in turbulent shear flow have been proposed by a number of researchers. There are, however, limited experimental...*

Column-Plate Interaction in Flat Slab Structures

*Investigations are made on the influence of column deformations on the stress distribution in flat slab structures, which are assembled from rectangular plates and columns with rectangular...*

Galloping Oscillations of Prismatic Structures

*Galloping oscillations can arise above a certain onset wind velocity with lateral force coefficient A*

_{1}> 0 (unstable cross sections) and also...Effects of Irregular Wave Trains on Rubble-Mound Breakwaters

*Results of model tests on a typical cross section of a rubble-mound breakwater are presented. The structure was protected against wave attack by a cover layer consisting of a double layer...*

Seepage from Trenches through Nonhomogeneous Soils

*Infiltration from shallow trenches of arbitrary cross-sectional shape and through a layer of nonhomogeneous soil was studied analytically. The soil layer is underlain by a bed of gravel...*

Torsion of Bars of Regular Polygonal Cross Section

*The present paper deals with an analytical solution of Saint Venant's problem in bars of regular polygonal shapes. Expressions for stresses and torsional constants are obtained in terms...*

Multicell Curved Girder Model Studies

*The behavior of a single two-span, three-cell plexiglass model is predicted by the Slope Deflection Fourier Series Technique. This analytical technique had previously been applied to only...*

Seepage from Shallow Open Channel

*An approximate Darcy solution is obtained for the two-dimensional seepage from an open channel which is placed upon a homogeneous, isotropic aquifer of relatively large depth. The linearized...*

Failure Modes of Folded Sandwich Panel Roofs

*Folded sandwich plate structures make effective light-weight roof structures capable of carrying relatively high loads. Two models were tested. The first had a span of 9.5 ft (2.90 m)...*

Economical Design of Presstressed Plate Girder

*The limit states design concept is employed. Relations expressing statical properties of the cross section; geometry of the system; and equilibrium, continuity, and strength-conditions...*
