An Efficient, Accurate Technique for Navier-Stokes Solution
Solution of the Navier-Stokes equations for a Newtonian, incompressible fluid (such as water) requires both accuracy in the assuring conservation of mass and efficiency of convergence....

Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....

Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...

River Wave Response to the Friction-Inertia Balance
The changing character of the solution of the Saint-Venant equations for river flow problems with the dimensionless parameter F//I reflects a changing balance between friction and inertia....

Time of Concentration in Small Rural Watersheds
A comparison was performed between the exponents of the independent variables L, S and i of the four-parameter time of concentration equation and eleven frequently encountered equations....

Response Charts for Designing Against Nuclear Overpressures
The single-degree-of-freedom equation of motion for an elastic-plastic system with a nuclear airblast overpressure forcing function is nondimensionalized and solved. Solutions are presented...

Limiting Performance and Design by Reanalysis of Structures for Blast Resistance
Limiting performance is the absolute optimal response of a structure under a specified transient load. Reanalysis methods are computational techniques for analyzing locally modified large-scale...

Microcomputer Assisted Bridge Rating
Before microcomputers can be useful to those officials responsible for rating the approximately 576,000 bridges in this country, software systems must be developed to analyze and rate...

The Lanczos Method in Structural Dynamics
The solution of the equations of motion often results in the solution of an eigenvalue problem in which the system matrices are large. Traditionally, the solution of this problem has employed...

Improved Method for the Dynamic Response of Bilinear Systems
A procedure is presented to eliminate the error introduced in the step-by-step numerical integration of the equations of motion of hysteretic bilinear systems subjected to earthquake excitations...

Vibrations of Submerged Solids in a Vibrating Container
Dynamic forces on a vibrating submerged solid cylinder in both closed and open-top rectangular containers are evaluated. The submerged cylinder is attached to the base of a dynamically-excited...

Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...

Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...

Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...

Comparison of Wave Overtopping Prediction to Measurements from Large-Scale Model Tests
A recent large-scale physical model study was sponsored by Arco Alaska, Inc. , to evaluate slope designs for an Arctic offshore oil drilling island. The drilling island will be located...

Loads Due to Human Movements
The live loads due to human actions are random functions being modeled from data obtained from tests to determine load histories for the actions of individuals and small groups of people...

On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...

Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...

Application of Preflexed Composite Beams to Continuous Bridges
A preflexed beam is a type of concrete encased steel beam of which prestressing has been introduced in the lower flange concrete. Recently, the preflexed composite beams were applied to...

Scheduling in Manually Controlled Canal Irrigation Delivery Systems
The effects of canal transients on scheduling water delivery to an irrigated area are described using a linearized form of flow equation obtained from a zero-inertia momentum equation...
