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...
Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...
Unit Hydrograph Derivation Using Geographic Information System
Geographical information system (GIS) data management and processing functions are used to develop synthetic unit hydrographs using input data consisting of digital elevation models (DEM)...
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...
A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....
Innovations for NDT of Concrete Structures
The proposed paper presents three recent innovations for sonic and ultrasonic Non-Destructive Testing (NDT) of concrete structures which greatly increase the utility and speed of many...
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,...
Dynamic Parameters Analysis of Piles
This paper presents an analysis for the dynamic parameters of a single pile. The analysis allows consideration of pile-soil interaction, soil natural layered behavior and floating pile...
A Numerical Study of Kinematics of Nonlinear Water Waves in Three Dimensions
We present a new method for analyzing the kinematics of nonlinear water waves in a three-dimensional domain. This method is based on our extension and generalization of the mixed-Eulerian-Lagrangian...
Sea Floor Wave-Induced Water Kinematics for Design of Pipeline
A statistical model is presented for horizontal velocity and acceleration of water particles beneath storm seas near the sea floor. An expansion of the kinematics with basis functions...
Recent Wave Kinematics Experimental Studies
Kinematics in the near surface region of water waves have been measured with a laser Doppler anemometer in the laboratory. The major results of these recent wave kinematics measurements...
Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...
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....
Radiocolloid Transport in Saturated and Unsaturated Fractures
Studies have shown that radionuclides and toxic materials can attach to colloidal particles in groundwater or are themselves colloids. Since these contaminated particles can migrate several...
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...
