Quality of Works in RCC in France: A Contractor's Solution
Bec Freres S. A. , a French dam contractor, introduced the technique of roller compacted concrete (RCC) into France. The first two French RCC dams were built as a result of a program of...

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...

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...

Geosynthetics for Soil Improvement: A General Report and Keynote Address
The paper summarizes major developments in the field of geosynthetics since the previous symposium in 1980. The paper addresses the engineering functions of major types of geosynthetics,...

Clogging Study of Geotextile with Weathered Mudstone
This paper focuses on the combined use of fly ash and geotextiles as a solution for the typical engineering problem of weathered mudstone slopes encountered in Taiwan. In situ collapsed...

Geosynthetics in the NATM Tunnel Design
This paper describes the Design Methodology for the New Austrian Tunneling Method (NATM) with special emphasis on the geotextile and geomembrane commonly used in the waterproofing design...

Pull-Out Response of Geotextiles and Geogrids (Synthesis of Available Experimental Data)
During the past 15 years, there has been a considerable growth in the use of various materials to reinforce soils. The rapid development of geosynthetics and their increasing use in soil...

Shallow Foundation on Sand Underlain by Soft Clay with Geotextile Interface
One technique for improving the load-bearing capacity of shallow foundations on soft clay soil is to construct them over a compact granular fill laid over the clay layer. However, the...

Full Scale Foundation Trials on Grid Reinforced Clay
The paper describes the results of full-scale testing of strip footings on an alluvial clay site. Existing theory is briefly discussed but shown to be of little relevance to the consolidation...

Finite Element Analyses of the St. Alban Test Embankments
Finite element analyses were performed of three embankments on sensitive clay that were constructed to failure at St. Alban, Quebec. One of the embankments was reinforced with flat-lying...

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...

Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...

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...

Mechanisms of Subsidence Induced Damage and Techniques for Analysis
Structural damage due to mining induced subsidence is a function of the nature of the structure and its position on the subsidence profile. A point on the profile may be in the tensile...
