RCC in Dams in Australia
The design, construction and performance of the first three dams constructed in Australia, using RCC are described. Aspects covered in the paper include designing for zero cohesion between...

Saco Dam?South America's First RCC Dam
Because of cost and a lack of suitable embankment materials, Saco Dam at Nova Olinda in Paraiba, Brazil, was redesigned and built with lean roller compacted concrete (RCC). The structure...

Roller Compacted Concrete Design for Urugua-I Dam
Gravity dam construction by the roller compacted concrete method (RCC) has received widespread interest following completion of Shimajigawa Dam in Japan (1981) and Willow Creek Dam in...

RCC Pavements in Tasmania, Australia
Over 60,000 m**2 of high strength Roller Compacted Concrete (RCC) pavement has been completed in Tasmania, Australia, since December 1986. Projects have ranged from footpaths and small...

Proportioning RCC Pavement Mixtures
The U. S. Army Corps of Engineers has begun using roller compacted concrete for construction of heavy-duty pavements and low volume streets and roads which are exposed to low-speed tracked...

RCC Storage Pads at Tooele Army Depot, Utah
Two 30. 5 m (100 foot) by 91. 4 m (300 foot) ammunition storage pads, each 381 mm (15 inches) thick, were constructed by the Sacramento District of the U. S. Army Corps of Engineers in...

Rennick Yard RCC Pavement Design and Construction
Rennick Yard roller compacted concrete paving project consisting of 136,000 multiplied by (times) yd**2 (113,710 m**2) was completed in June 1986. The design load for this project was...

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...

Vibration Analysis Using a Parallel Lanczos Method
A parallel eigenvalue solution algorithm, based on the Lanczos method, has been developed, implemented on a Flexible Computer FLEX/32 multi-processor, and applied to an example structural...

Concurrent Nullspace Methods for Multibody Systems
This paper presents a new concurrent multiprocessing algorithm for simulating the dynamics of constrained multibody systems. The systems considered are quite general in nature; they may...

Parallel Algorithms for Structural Optimization Under Dynamic Loading
Parallel algorithms and strategies are outlined for optimal design of frame structures subjected to dynamic earthquake loading. Parallelism is extracted in six areas: substructuring of...

Structural Analysis and Parallel Computers
This paper discusses the implementation of a parallel program that performs a two dimensional rigid frame analysis on a NCUBE/7 hypercube multicomputer. The program was written in C and...

A Finite Element System for the CDC CYBER 205
This paper summarizes some of the special considerations required for finite element system development on the CDC CYBER 205. A means of constructing an efficient database is presented....

Finite Strip Method in a Parallel Computing Environment
The finite strip method has been used to model many systems in structural mechanics. The orthogonality of appropriately selected shape functions allows a continuous system to be effectively...

Laboratory Study of Geogrid Reinforced Soil Walls
The paper describes the construction and testing of three (3) large-scale geogrid reinforced soil retaining wall models. The models were 3 m high and were built in the RMC Retaining Wall...

Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...

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...
