Structural Analysis of Wood Floor Systems
A combined Fourier series and finite element analysis of wood floors is presented, and its implementation in a computer with small core memory is discussed. Predictions using the model...

Collapse Loads of Laced Columns
The imperfection sensitivity of laced columns is investigated, the imperfection consisting of both a local and an overall geometrical imperfections. A simple numerical method is given...

Intra-CBD Secondary Travel Patterns of Downtown Workers
Previous Downtown People Mover (DPM) feasibility studies have shown that the majority of the average daily DPM trips will be made by downtown workers during their travel to and from the...

CW Microwave Location of Voids Beneath Paved Areas
The problem of locating voids beneath paved areas is a perplexing and costly one. Usually voids are investigated by test borings, which is a discontinuous hit-or-miss process. The use...

Columns with Semirigid Joints
The influence of realistic semi-rigid end restraint on the strength and behaviour of real steel columns is investigated. An analytical procedure is developed which includes the effects...

Circular Wall Jets in Coflowing Streams
The mixing and diffusion of circular turbulent wall jets in coflowing open channel streams is discussed with the ratio of the jet to channel velocity varying from 2 to 30 and the depth...

Obtaining the Layout of Water Distribution Systems
An essential first step in the design of a municipal water distribution system is the determination of the locational placement or layout of the links of pipe that will form the system....

Infiltration Formulas by Curve Number Procedure
The Soil Conservation Service (SCS) curve number procedure for estimating runoff volume is examined in terms of the validity and applicability of the derived infiltration equations. Two...

Computer Applications in Water Resource Planning
Due to the complexity and inter-disciplinary nature of water resource planning and management, and because many of the problems are site and situation-specific, general-purpose computer...

Application of Cost-Flow Forecasting Models
Cost-flow models are formulated for forecasting the cumulative cost-flow in housing and public buildings, as a function of total cost and construction period. This permits to estimate...

Optimal Grillage Layout for Given Natural Frequency
The problem of minimizing the volume of structural material of an elastic grillage subject to a prescribed value or the fundamental frequency of free transverse vibrations, is considered....

Internal Hydraulic Jump in Stratified Counterflow
Based on a Boussinesq approximation of the governing momentum equations for an internal hydraulic jump in a two-layer counterflow, two important properties of an equal counterflow are...

Postbuckling of Rings under Two Uniform Loads
The interaction effect of the normal and centrally directed pressures on the initial postbuckling behavior of a thin elastic circular ring buckling freely in its own plane is investigated...

Imposed Ground Strain and Buried Pipelines
A technique for the analysis of buried pipelines subjected to longitudinal soil strain resulting from earthquakes or manmade underground explosions is presented. The effects of this soil...

Symmetrical FFT for Migrating Waves
A Fast Fourier Transform (FFT) technique is developed to analyze migrating waves for phase relationships as well as spectra. The problem of phase leakage, which arises through the use...

Lateral Bed Load Transport on Side Slopes
Lateral bed load transport is studied in laboratory flume and wind tunnel. Introduction of laterally inclinable wind tunnel permits accurate measurements of shear stress on side slope...

The Effect of Contract Wording on Inspector Liability
Design professionals should endeavor not to write burdensome or inaccurate contracts; i.e., those that inaccurately describe duties. Inspector...

Probabilistic Description of Hurricane Wind Speeds
Information is presented on the parameters of the best fitting Weibull distribution estimated for simulated hurricane windspeeds. The effect of the assumption that an Extreme Type I distribution,...

Organizing Engineering Volunteers for Disaster Relief
National and manmade disasters disrupt people's lives and make them dependant on others. This is particularly severe in the least developed countries often subject to their...

Water Resources in Developing Countries
Most of the nations of the world are concerned with providing water to as many people as possible during the Decade of the 1980's, (The International Drinking Water and Sanitation...
