Axial Hysteresis Behavior with End Restraints

*Parametric study of axially loaded steel members with symmetrical rotational end springs (connections) was performed. The main parameters are the connection flexural strength, the effective...*

Inelastic Response of Restrained Steel Tubes

*Eighteen specimens made from 1 in. (25-mm) square tubes with welded gusset plates were tested under repeated axial loading. Length of the specimens varied from 20 in. to 54 in. (510mm...*

Impedance Functions of Piles in Layered Media

*An approximate analytical solution is established that makes it possible to calculate impedance functions (stiffness and damping) of a single pile embedded in layered media. The pile can...*

The Poisson Effect in a Column with Axial Strain

*The writer's previous work on buckling and post-buckling of a column with axial strain is generalized by allowing the cross sections along the member to change size and shape...*

Considerations for Pipeline Crossings of Rivers

*The criteria and procedures deemed necessary in the preparation of safe and economical pipeline river and stream crossing design are presented. Background data on the effect of industry...*

Three-Dimensional Open Channel Flow

*An open channel flow is usually three-dimensional consisting of the primary and secondary flows. The primary flow is defined herein as the flow component in the longitudinal direction...*

Direct Solution to Problems of Open Channel Transitions

*Existing methods of solving problems of open channel transitions involve trials-and-error solution of higher degree equations and no direct solutions are available in technical literature....*

Cross-Sectional Imperfections and Column Stability

*A method to determine the elastic buckling strength of imperfect closed polygon columns has been developed. A set of eight equilibrium equations was developed but was reduced to a set...*

Lower Bound Limit Design of Concrete Structures

*A lower bound method has been developed for the limit design of indeterminate concrete structures subjected to torsion. In this method, a stress resultant field that satisfied all the...*

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...*

Prediction of Hysteresis of Reinforced Concrete Members

*The endochronic theory for inelasticity and failure, previously established, is used to predict the response of reinforced concrete beams in cyclic bending at large strains. Cross sections...*

Rationalizations of Sections Properties Tables

*Round-off to nearest (and usually larger) available standard cross section involves a component of waste in design that, together with other relevant costs, should be minimum. Commonly...*

Torsional Vibrations of Pile Foundations

*Figures are presented to facilitate this application and the response of various representative footings to torsional excitation is also shown. For a pile group the contribution of pile...*

Effect of Sediment Load on Stable Sand Canal Dimensions

*An experimental study was taken up by the writers with the object of providing a clear picture of the effect of sediment load on the dimensions of stable canals. These experiments were...*
