Aggregate Gradings for Nuclear Concrete
Evaluation of concrete shows that segregation, inherent in rehandling of coarse aggregate, is significantly reduced in the large mixers used in concrete production. The investigation also...

Compression Overlapping Precedence Networks
A study is presented, which is directed at finding a solution to the problem of compressing networks having overlapping activities. The method involves the use of cost duration charts,...

Contract Administration: A Resident Engineer's View
Professional liability related to field work is a major concern of the consulting profession. Field personnel should review the plans and specification in the pre-construction period and...

Games People Play with Work Sampling
Guidelines and principles are presented for planning and implementing a work sampling program. Principles to be followed include careful planning to fulfill objectives, the need to be...

Modernized Metric System—SI—The American Choice
Americans have played a major role in the development of the new International System of Measurement Units (SI). The world is moving rapidly in the adoption of this modernized metric system....

Managerial Decisions Under Inflation
The problems of managerial decision making under inflation are discussed, and some solutions are offered. The risk of estimating under inflation is explained, and a method to improve the...

Biomass as Alternative Energy Source
The potential for biomass utilization as a source of fuel, petrochemicals and petroleum-sparing substances is reviewed. The choices for cultivating biomass, utilizing it directly as an...

Estimating Underground Power Station Costs
Planners involved in evaluating pumped-storage alternatives found the capital cost of the underground powerstation directly related to the installed capacity. Estimates for three underground...

Coal-Fired Reference Plants: Project Benefits
It is expected that requirements for new electric generating capacity will necessitate shortened engineering and construction schedules for future coal fired projects. The reference plant...

Ash Pond Construction to Meet Performance Requirements
The establishment of environmentally acceptable ash disposal reservoirs for a steam electric station is achieved through the design of impervious embankments and foundation cutoffs. Field...

A design approach for satisfactory and cost effective rotary machine foundations, especially fan foundations, is presented. The often used minimum stiffness criterion for the foundation...

Cooling Tower Practice in Germany: State of the Art
A rapid development in design and construction of natural draught cooling towers has taken place in Germany. Research has been concentrated on theory and analysis of shells, on acting...

Full-Scale Tests on Ground Anchors in Fine Sand
A series of ground anchors of varying lengths were installed in a medium dense sand, with a veiw to study as many as possible of the variables influencing anchor behaviour and load transfer....

Numerical Models for Track Support Structures
Three finite element formulations based on one-, two-, and three-dimensional idealization for analysis of railroad track support structures are presented with major emphasis on the three-dimensional...

Horizontal Stiffness and Damping of Single Piles
Simple expressions are developed for the equivalent horizontal spring and damping coefficients at the top of an end-bearing pile embedded in a uniform linear soil. Beam on elastic foundation...

Probabilistic Analysis of Deposit Liquefaction
A probabilistic methodology is presented for liquefaction analysis of horizontally layered sand deposits, subjected to vertically propagating seismic S waves. Three different deposit models...

Shallow Foundations for Tall Structures in Florida
The use of shallow foundation systems with measurable but tolerable settlement of major building complexes constructed in the Miami, Florida area is demonstrated by three case histories,...

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...

Single Pile Response to Cyclic Lateral Load
An analysis is presented for the deflection of a pile in clay subjected to quasi-static cyclic lateral loading. This analysis is an extension of the elastic continuum analysis for static...
