Design of Seepage Control Systems for RCC Dams
As the reservoirs of the first generation of roller compacted concrete (RCC) dams have been filled, several have exhibited significant amounts of seepage, a fact that has been of concern...
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...
Residential Damage in an Area of Underground Coal Mining
In order to estimate the potential for future subsidence-related residential damage, a statistical analysis of past residential damage in the Boulder-Weld, Colorado, coal field was performed....
Advanced Reconstruction for Subsidence-Damaged Homes
To address many of the residential damage-reconstruction problems from mine subsidence a research and development project was undertaken in Illinois. Phase I of this project is complete...
Subsidence Over AML and Its Causes?A Case Study
Subsidence over abandoned mined lands can be attributed to several causes. For purposes of compensation and liability and developing remedial measures, it is essential to identify the...
Load Combinations for Codified Design
Loading requirements used in current standards for structural design are not consistent in their conceptual basis, appearance or use. Unified limit states design procedures for structures...
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...
A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...
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...
