Construction of Upper Stillwater Dam
This paper describes the equipment, placing methods, and peak production rates from the contractor's viewpoint for both the Roller Compacted Concrete and the Slipformed Facing...
Quality Control/Inspection�Upper Stillwater Dam
Roller compacted concrete construction, or RCC, is a relatively new method of constructing concrete dams and involves placing and spreading no-slump concrete in horizontal layers and compacting...
Whither Roller Compacted Concrete for Dam Construction?
During the formative years of the roller compacted concrete (RCC) dam, three different approaches to the design have evolved; the lean RCC dam, the RCD (rolled-concrete dam) method and...
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 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...
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...
Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
First-Order Reliability Analysis of Groundwater Flow
A method for stochastic analysis of groundwater flow based on the first-order reliability approach is presented. The method is well suited for problems in which statistical information...
Simulation with Ordered Discrete-Stochastic Samples
In order to account for the viscoplastic deformations, leading to the failure of structures, the nonlinear dynamic responses can be obtained with convenient spatially discretization schemes....
Stochastic Fem Analysis of Nonlinear Dynamic Problems
This paper deals with the stochastic finite element analysis of nonlinear structural dynamic problems, using Monte Carlo simulation techniques. The stochasticity of those problems arises...
Orthogonal Expansion for Beam Variability
A new method for the solution of problems involving random media is proposed. The medium property is represented by a stochastic process. The method makes use of an orthogonal expansion...
Sensitivity Analysis of Nonlinear Fem
A method of sensitivity analysis is developed for nonlinear structural systems which are governed by incremental finite element equations. The formulation originates in the perturbation...
Reliability of Geometrically Nonlinear Structures
A procedure for first- and second-order, finite-element reliability analysis of geometrically nonlinear structures under static loads is presented. Structures are either linear or nonlinear...
Stochastic Finite Element Analysis of Frames with Flexible Connections
A procedure is proposed in this paper for the stochastic finite element analysis of frames with stochastic connection rigidity. A beam-column element is used to simulate the connection...
Failure Probability Estimation of Series Systems
In this paper, an approximation scheme is presented for analysis of series structural systems where no exact solution exists. If the safety indices of the individual failure functions...
