Planar Strength of Restrained Beam Columns
A theoretical method that describes the planar, elastic-plastic behavior of a beam-column loaded at the ends and along the length is described. The theory considers the three important...

Vertical Circulation in Density-Stratified Reservoir
The paper presents a mathematical model of vertical circulation in density-stratified reservoirs. An analytical solution of the formation of circulation regions is presented. The solutions...

The V-Shaped Broad-Crested Weir
A discharge measurement structure with a triangular control section and a broad crest provides a rather wide measuring range while the head-discharge relation remains unaffected by tailwater...

Measurmment of Velocities in Solitary Waves
The water surface profiles and corresponding water particle velocities of several solitary waves have been obtained. The measurements of the horizontal and vertical velocity components...

Structural Design of Cemented Pavement Layers
A mechanistic structural design procedure for pavements containing cement- and lime-treated layers is outlined. The procedure includes provision for use of a range in traffic wheel loadings,...

Transit Performance Evaluation Model
An analytical methodology, known as the Transit Performance Evaluation Model, has been extended and applied. The model is used to evaluate the effect on transit performance from short...

Aircraft Evaluation in Air Network Planning
The relationship between aircraft technology and the structure of air service networks in short haul systems is investigated. The analysis is based on an optimal frequency assignment model...

Behavior and Design of Reinforced and Composite Concrete Structures
The force-deformation equilibrium equations of reinforced and composite concrete columns are formulated, from which moment-curvature-thrust relationships are developed. The cross section...

Task Committee on Engineering Education: Report to the Board of Direction
Engineering education, not civil engineering education alone, is in a crisis which could seriously damage the engineering profession and the national interest. Too few graduates are earning...

Ductility of Square-Confined Concrete Columns
A brief review showed considerable differences in the quantity of rectangular hoops required by various seismic design codes in the potential plastic hinge regions of rectangular reinforced...

Probability of Survival in a Blast Environment
The probability of survival of people located in personnel shelters when subjected to the blast effects produced by the detonation of a 1-MT weapon near the ground surface is studied....

Dynamic Response of Plate on Elastic Half-Space
Analytical results are presented for the dynamic response of a plate bearing on an elastic half-space and subjected to harmonic forces. The present work represents a departure from existing...

Dispersion in Tumbling Flow
Steep mountain streams are often in the tumbling flow regime, that is alternating sub- and super-critical flow with energy dissipation caused mainly by sudden changes in slope and cross...

Stresses and Displacements in Cross-Anisotropic Soils
An analytic investigation is presented on the effect of soil cross-anistropy on surface displacements and stress distributions in a homogeneous thick soil deposit (halfspace) subjected...

Ko - OCR Relationships in Soil
The relationships between Ko and OCR are investigated for primary loading - unloading - reloading conditions. The study reviews laboratory data from...

General Contractor Project Control Practices and MIS
Building contractor project control, information documentation, flow practices, and the attributes of project management personnel provide the focus for this paper. The methodology employed...

TVA Hydro Scheduling Model: Practical Aspects
Computer programs and mathematical methods have been developed to model long term week-to-week variations in water level, discharge and electrical generation for the 42 reservoirs operated...

Dynamic Formula for Pressure Injected Footings
The mathematical derivation of a dynamic pile-driving formula for the installation of Pressure Injected Footings (Franki Piles) is presented. The usefulness of such a formula, despite...

Selection of Pavement Joint Sealant Material
A review of literature shows joint sealant selection should be based on the design, construction and environmental variables. Satisfactory performance for one set of conditions does not...

Generalized Stiffness Matrix for Thin Walled Beams
Stiffness matrix for a structural member is obtained using the differential equations derived by V.Z. Vlasov. Presence of additional off-diagonal elements over the conventional tridiagonal...
