Design and Construction of Lower Chase Creek Dam
Lower Chase Creek Dam is a roller compacted concrete flood control dam located in a generally dry creek in eastern Arizona. Dam design, including the site investigation and start-up of...
Construction of Elk Creek Dam
Construction of Elk Creek Dam, located in Southwest Oregon, is currently underway with completion scheduled for September 1988. The main dam contract was awarded to Ohbayashi Gumi Ltd....
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...
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...
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...
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...
Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
Load-Sharing and Reliability of Wood Systems
A methodology for the study of reliability of light-frame wood structural systems is presented. Reliability levels associated with the bending strength limit state of such systems are...
Methods to Estimate Parametric Sensitivity in Structural Reliability Analysis
Many different approaches are used in structural system reliability to estimate the probability of failure. In this paper, methods to obtain the sensitivity to the distribution parameters...
On the Evaluation of System Reliability Through Automatic Generation of Failure Modes
This paper proposes a method for the evaluation of structural failure probability taking into account all the potential failure modes. At first, the failure paths to produce failure modes...
Fatigue Reliability and Inspection in Redundant Structural Systems
The reliability of redundant structural systems under fatigue including updating by inspection is studied using two different formulations, i.e., the stress intensity space and the crack...
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...
Lifetime Reliability of Wood Structural Systems
A model to predict ultimate capacity reliability of wood systems is developed. The model is analogous to Markov cumulative damage models. System ultimate capacity is defined as failure...
Multicriterion Reliability-Based Optimization of Structural Systems
The optimization of nondeterministic structural systems under random loads is currently performed by single-criterion reliability-based optimization methods. However, in structural design...
Reliability of Multistate Structural Systems
The theory of system reliability consists of establishing the relationship between the reliability of a complex system and the reliability of its components. Often, the system and its...
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...
