Soil-Structural Interaction and Concrete Tie Design
Experimental data and theoretical argument are presented to show that the optimum length for a concrete tie of uniform cross section is 1.67 to 1.71 times the distance between the two...

Forced Plumes in a Stratified Reservoir
A comprehensive two or three-dimensional model for a forced plume is described in which there are no restrictions necessary in the choice of cross-sectional velocity or density profiles,...

Circumferential Diffusion in Pipe Mixing
A method is presented and used for evaluating an average circumferential mass diffusivity for steady, uniform, turbulent pipe flow. The method is based on the analytical solution of the...

Lateral Buckling of Intersecting Connected Beams
Under transverse loadings, components of gridworks composed of deep slender beams may become unstable with the response characterized by twist and lateral deflections of the beams. A beam-cross...

Experiments on Surface Buoyant Jet
An experimental investigation of a surface buoyant jet is presented. The densimetric Froude number and the Reynolds number of the discharge channel were 3.6 and 33,000, respectively. Longitudinal...

Large Displacement Inelastic Analysis of Beam-Columns
The formulation of a variational virtual work equation for describing internal work for an arbitrary thin-walled beam of open cross section subjected to large displacements is reviewed....

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...

Maximum Load Design of Cold-Formed Steel-Channel Beams
An alternative to minimizing the weight of a cross section for a specified load is to maximize the load capacity of a structural member of a specified weight. General conditions for equivalence...

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...

Inelastic Section Response by Tangent Stiffness

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...

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...
