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....
Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...
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...
A Mathematical Tool Set for SORM Reliability Methods
FORM and SORM methods are used for approximating failure probabilities. Here an overview of the main mathematical results of SORM methods is given: Classification of asymptotic behavior,...
Site-Dependence of Spatial Coherency
The spatial coherency of ground motion from nine dense arrays are analyzed to examine the site-dependence of spatial coherency. The spatial coherencies computed for arrays located on alluvium...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Evaluation of Seismic Soil Response Using Stochastic Linearization
This paper discusses the use of stochastic linearization to non-degrading soils. First, the Bouc-Wen model parameters are reviewed. Monte Carlo simulation results are compared with the...
Probabilistic Order of Chaotic Dynamics
A chaotic dynamics system generally turns a deterministic input into a random-like output. Although the response is not directly predictable in the deterministic sense, its probabilistic...
Probabilistic Particle-Related Constitutive Model for Clayey Material
Particle-related (microscopic) soil modeling has attracted attention of research community in recent years, because of complication and shortcoming associated with inelastic macroscopic...
Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
Reliability-Based Specification of Design Load-Effect for Penetrating Fragments and Debris
This paper presents the derivation and application of a simplified reliability-based approach for selecting design fragments/debris particles for use in protective design. Using this approach,...
Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...
Assessment of Derived Flood Frequency Distributions
Derived flood frequency distributions based on the geomorphologic IUH are evaluated in this work. Two existing approaches, the methods of Hebson and Wood (1982) and Diaz-Granados et al....
A More Rational Approach to Pavements
It is the intent of this paper to demonstrate how purely probabilistic arguments can be used to formulate a rational (phenomenonological) model of the particulate media that comprise pavement...
Adhesives and Structural Plastics
An overview of some primary considerations for the use of adhesives and their advantages in connection of structural plastics is presented. Effective joint geometries, surface preparations,...
Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...
Small-Scale Meteorology of Freezing Precipitation
Freezing rain and glazing are extremely disruptive to transportation, communication and power transmission. Local variations in the occurrence of freezing rain may be difficult to forecast....
Effect of Material Heterogeneities on Flow Through Porous Media
Modeling studies were conducted to determine the effects of material heterogeneities on the flow of water through rock. Multiple numerical calculations were made using random variations...
A Probe Method for Measuring In Situ Rock Thermophysical Properties
The application of a thermal probe method for in situ thermophysical property measurement is analyzed. The REKA method (Rapid Evaluation of k and alpha) involves a single-borehole probe...
