Probabilistic Approach to Stress Distributions for Orthotropic Wood Plates
Probabilistic approach to the stress distributions of an orthotropic wood plate is discussed. The stress distributions for the orthotropic elastic media are fully dependent of the material...
Load Resistance Factor Design of Aluminum Structures
Load and Resistance Factor Design (LRFD) is a reliability-based approach to design with uncertainty. It involves the explicit consideration of limit states, multiple load and resistance...
Study on Reliability of Actual Steel Structure Using Measured Data
The measurement of uncertainties was taken on an actually constructed steel structure. The stress and strain of each part of the structure are calculated based on the conditions assumed...
Statistical Properties of Prestressed Concrete Beams in Shear
Monte Carlo simulations were performed on prestressed concrete rectangular and tee-section beams in shear produced by a single concentrated load at mid span. The truss analogy model was...
Reliability-Oriented Materials Design of Composite Materials
A basic formulation for evaluating safety index of unidirectional fiber reinforced laminate is presented. The proposed formulation is based on in-plane failure criteria of composite laminate...
Verification of NESSUS Code on Space Propulsion Components
Application of probabilistic finite element method to the structural analysis of typical space propulsion components such as turbine blades and high pressure ducts is reported. The study...
Buried Structural Capacity of Insituform?
In July 1988, a test was conducted at Utah State University to determine the structural support that can be provided to a failing rigid pipe system through the use of the Insituform process....
Strides in Nondestructive Testing
Stress wave methods of nondestructive testing are increasingly used in civil engineering applications. Four case histories of the use of different types of stress wave testing are given....
Mudflow Rheology in a Vertically Rotating Flume
Joint research by the U.S. Geological Survey and the University of Missouri-Rolla currently (1990) is being conducted on a 3.05 meters in diameter vertically rotating flume used to simulate...
Rheological Properties of Simulated Debris Flows in the Laboratory Environment
Steady debris flows with or without a snout are simulated in a 'conveyor-belt' flume using dry glass spheres of a uniform size, 5 or 14 mm in diameter, and their...
Unsteady Flow of Bingham Viscoplastic Material in an Open Channel
An analytic solution for transient flow of a Bingham viscoplastic material in an open channel is presented. The solution for the response to a time-varying pressure gradient predicts shear...
Longitudinal Surface Profiles of Granular Debris Flows
Longitudinal surface profiles of granular material flowing down an inclined plane were studied by means of theoretical analysis and laboratory experiments. There are two driving forces...
