Probabilistic Characteristics of a Sliding Structure Via New Stochastic Linearization Methods
New, non-classical stochastic linearization techniques are applied to solve the titled problem. Two alternative criteria, suggested by X. Zhang and I. Elishakoff, respectively, are evaluated....
Reliability Consideration in Shakedown Analysis
Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual...
Parameter Estimations of Structural Dynamic Systems
In this paper, time-domain methods for estimating the system parameters and the modal properties of linear structural dynamic systems are studied. The autoregressive and moving average...
Evaluation of Expansive Clay Soils in Tucson, Arizona
Research was conducted to investigate the mineralogy, engineering properties, and regional distribution of expansive clay soils in Tucson, Arizona. Data derived from X-ray diffraction...
Geotechnical Database Manipulation to Effect Stochastic Analysis
Existing or easily-developed databases of regional geotechnical information can be used to estimate prior probability distributions and parameters for use in stochastic analyses. Prior...
Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...
A Criticism of Statistical Methods in Probabilistic Models in Structural Reliability
The usual statistical models, classical and Bayesian, are not well suited for problems of structural reliability, since here we have rarely as assumed for these models a sequence of identical...
Sensitivity Evaluation of Simulation Methods for Reliability Assessment
Commonly used reliability assessment methods include the first-order methods, second-order methods, and Monte Carlo simulation methods with or without variance reduction techniques. The...
High Order Statistics in Structural Reliability
The new simulation technique described in this paper attempts to avoid the significant amount of arbitrariness involved in the choice of the sampling distribution in the increasingly popular...
Experiences with Experimental Design Schemes for Failure Surface Estimation and Reliability
When using FORM and SORM to predict the probability of failure for a structural component a model for the failure function has to exist. For certain structural components a mechanical...
Slepian Process of a Non-stationary Process
An algorithm for simulating a zero-mean non-stationary Gaussian process over a fixed interval [0,T] with given arbitrary covariance function as well as the associated Slepian model process,...
Stochastic Finite Element Analysis of a Damped Beam on Random Foundation and Subjected to Fast Moving Loads
The dynamic effect of fast moving loads on a rail is analysed by the perturbation-based stochastic finite element method. The rail is modeled as an elastic beam resting on the Winkler...
Finite Element Dynamic Reliability Analysis with Condensation
This paper presents the use of matrix condensation in stochastic finite element-based reliability analysis of structures subjected to dynamic loading, in the context of modal superposition....
Reliability of Nonlinear Frame Structures by SFEM
A method is proposed for the reliability analysis of nonlinear frame structures with flexible connections. The uncertainty of a connection is represented by a group of random moment-relative...
Calibration of Redundancy Factors for Highway Bridges
The object of this study is to develop a framework for considering redundancy in design and load capacity evaluation of highway bridge superstructures. The proposed method consists of...
Structural Reliability and Proof Testing for Highway Bridges
This paper proposes a set of reliability-based proof load factors for highway bridge evaluation, to determine target proof load and load rating. The target safety index used is consistent...
Predicting Effects of Subsidence on Landfill Caps
Groundwater protection at unlined, closed landfills relies upon limiting cover or cap infiltration. Depressions on closed landfills indicate infiltration from reduced runoff and loss of...
A Knowledge Based System with Uncertainty for the Soil
In this paper, we present the methodology that we used to develop the KBSOL Knowledge Based System for the soil. We describe the structure that contains the objects of the domain (layer,...
Reliability of Controlled Structures Subject to Real Parameter Uncertainties
This paper presents a systematic and probabilistically consistent approach for determining the likelihood that instability will result from the uncertainty inherently present in a controlled...
Effect of Active Control to Structural Reliability
Most available results in the study of structural reliability deal with idealized mathematical representation of structures. With model supported diagnosis of the structural condition...
