Roller Compacted Concrete with Marginal Aggregates
Roller compacted concrete is a technology which is vastly expanding beyond the traditional uses of pavement and dam oriented projects. Hornsby Bend Wastewater Treatment Plant required...
Corps of Engineers Experience with RCC Pavements
Roller compacted concrete pavements were first developed in the U. S. by the Corps of Engineers in 1975. Since that time, RCC pavements have been constructed throughout much of the U....
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Design of Roller Compacted Concrete Pavements
This paper reviews some of the differences between roller compacted concrete and conventionally constructed concrete pavements. These differences require additional consideration during...
Fly Ash Utilized in Concrete?Technology Update
Fly ash is frequently utilized as a pozzolanic substance in Portland cement concrete. Levels of such utilization, a reflection of current practice/technology, seem to have stabilized at...
Guidelines for Design and Construction of Pozzolanic Stabilized Base Course Mixtures
The American Coal Ash Association (ACAA) has developed a manual of recommended practice which contains guidelines for the design and construction of pozzolanic stabilized base course mixtures...
Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
Lateral Analysis of Drilled Piers Incorporating Soil Variability
In probabilistic studies, the mean or expected value of the parameter in question, along with its measured dispersion or standard deviation, are determined. In this study the Three Point...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Prediction of Concrete Creep and Shrinkage by Sampling on the Basis of Correlated Random Material Parameters
There are many random parameters which influence creep and shrinkage of concrete. In all of the previous probabilistic studies the parameters are assumed to be mutually independent random...
Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Actual Versus Assumed Behaviour of Girder Bridges
It is generally believed that the discrepancies between calculated and actual responses of bridges can diminish, to the point of being nonexistent, with refinement in the method of analysis....
Reliability of Cracked, Prestressed Girders
For prestressed concrete structures in non-aggressive environments or where corrosion-protected prestressing strands are used, it may be possible to allow flexural cracking into the precompressed...
Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...
Applying the Time-Reliability Equation
This paper presents a methodology for rigorously including time-varying elements of reliability through the use of the time-reliability equation. An example reliability analysis which...
Stochastic Risk Assessment for Structural Safety
Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper...
Building Code Requirements for Masonry Structures and Specifications for Masonry Structures
The proposed Building Code Requirements and Specifications for Masonry Structures presented in this book were developed by the Joint American Concrete Institute, American Society of Civil...
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Swiss Cheese Box Girders
Now going up in the French Alps, the Sylans and Glacieres viaducts have decks supported by three-dimensional arrays of concrete trusses. The superstructures look like concrete box girders...
High Strength High Rise
For the sixth time in history, a structure billed as the world's tallest concrete building (over 950 ft) is under construction in Chicago. The contractors describe the structure...
