Seismic Response of End Bearing Piles
A very simple analysis of dynamic soil-pile-supported mass interaction is presented as an aid to understanding pile foundations behaviour during earthquakes. The equilibrium equations...

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...

SPT Hammer Energy Measurement
A field measurement system and procedure which measures the energy delivered by a drill rig system was developed and successfully used to study the factors which affect delivered energy....

Pulverized Coal Ash as Structural Fill
Untreated pulverized coal ash, consisting of fly ash with varying percentages of bottom ash, was used as a structural fill material to support the foundation of a new precipitator for...

Vertical Vibration of Pile Groups
An approximate theory for vertical vibration of pile groups is presented. The theory accounts for dynamic interaction of piles in a group, weakening of the soil around the pile due to...

Embankment Construction: New Melones Dam
New Melones Dam, located on the Stanislaus River in central California, is a zoned earth and rockfill structure with a maximum height above foundation at embankment centerline of 637 feet...

Flow Under Weir on Scoured Bed
An approximate analysis for seepage flow under a weir, resting on isotropic porous medium of infinite depth, with a vertical sheet pile at the toe and a segmental circular scour, is obtained...

Gumbel's Extreme Value I Distribution: A New Look
Many basic hydrologic textbooks, following Gumbel's original work, advocate use of frequency factors dependent on an integer m for estimation of event levels using the Extreme Value I...

Complete Triaxial Stress-Strain Curves for Concrete
A method to predict the ascending and the descending parts of stress-strain curve of concrete subjected to triaxial compressive stresses is presented. The proposed analytical stress-strain...

Finite Segment Method for Biaxially Loaded RC Columns
The finite segment method is applied here to solve biaxially loaded reinforced concrete columns. The column is treated as a space structure after segmentation. The sections are divided...

Numerical Bending Analysis of Bridges
Related numerical procedures are described for the elastic analysis of arches by large deflection, second order and classical theories. These procedures essentially consist of simple and...

Reliability of Aluminum Beam-Columns
A review of reliability computation methods is presented. The strength of aluminum beam-columns is described, taking into account material and cross-sectional properties, initial imperfection...

Cooling Tower Shells Founded on Soil
A dynamic axisymmetric finite element model suitable for shells of revolution founded on ring footings is presented. The model consists of high-precision rotational shell finite elements,...

Acrosswind Response of Buildings
The acrosswind response of buildings is investigated. Expressions for the acrosswind loading are developed through the use of the spatio-temporal measurement of the fluctuating pressure...

Experiments on Closing Reinforced Concrete Corners
Reinforced concrete corners have inherently more flexural strength across the corner than at other sections when subjected to negative bending moments. The modes of failure and cracking...

Acoustic Techniques for Offshore Positioning
Acoustic positioning systems for accurately determining the location of a site, structure, or vessel in the ocean are described. The advantages of acoustic positioning systems over electromagnetic...

Problems in Administering Overseas Projects
Management of an overseas project can be successful if potential problems are recognized and considered early in a proposed new venture. Such problems include organizational structure,...

The American Engineer Overseas
More and more American engineers will be working overseas, many for the first time. Frequently materials, laboratories and hardware equipment are not available and the engineer must first...

Project Evaluation in International Development
Project evaluation methods used by the World Bank and the United Nations Industrial Development Organization are compared with regard to measures of value, use of shadow prices, discount...

Overseas Marketing Strategy
The personnel element in achieving and maintaining overseas marketing success is examined, and suggested strategies for selection, preparation, utilization and support of personnel for...
